Commission Implementing Regulation (EU) 2025/1707 of 25 July 2025 laying down rules for the application of Regulation (EU) 2024/1257 of the European Parliament and of the Council as regards specific methods, requirements and tests, including compliance thresholds, for OBFCM devices and OBM systems, characteristics and performance of driver warning systems and inducement methods and methods to assess their operation, EVP format and data and methods of communication of EVP data of motor vehicles of categories M1 and N1

Official Journal EN of the European Union L series 2025/1707 5.9.2025 COMMISSION IMPLEMENTING REGULATION(EU) 2025/1707 of 25 July 2025 laying down rules for the application of Regulation (EU) 2024/1257 of the European Parliament and of the Council as regards specific methods, requirements and tests, including compliance thresholds, for OBFCM devices and OBM systems, characteristics and performance of driver warning systems and inducement methods and methods to assess their operation, EVP format and data and methods of communication of EVP data of motor vehicles of categories M and N 1 1 (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EU) 2024/1257 of the European Parliament and of the Council of 24 April 2024 on type- approval of motor vehicles and engines and of systems, components and separate technical units intended for such vehicles, with respect to their emissions and battery durability (Euro 7), amending Regulation (EU) 2018/858 of the European Parliament and of the Council and repealing Regulations (EC) No 715/2007 and (EC) No 595/2009 of the European Parliament and of the Council, Commission Regulation (EU) No 582/2011, Commission Regulation

(EU) 2017/1151, Commission Regulation (EU) 2017/2400 and Commission Implementing Regulation

(EU) 2022/1362(1), and in particular Article 14(3), point (a) and Article 14(4), points (j), (k), (o), (s), (t), (u) and (v), thereof,

Whereas:

(1) Regulation (EU) 2024/1257 requires the Commission to set out procedures and testing methodologies, administrative provisions, procedures and methodologies for amending and extending emission type-approvals and data access, documentation requirements and templates for emission type-approval, conformity of production, in-service conformity and market surveillance for types of vehicles of categories M and N . By virtue of Article 5(2) 1 1 and (3) of Regulation (EU) 2024/1257, those rules should apply also to N vehicles designated as ‘Euro 7ext’ and 2 ‘Euro 7Gext’ in accordance with that Article.

(2) In particular, rules should be laid down regarding on-board monitoring (OBM) systems, excess exhaust emissions driver warning systems (EEEDWS), on-board fuel and electric energy consumption monitoring (OBFCM) devices, environmental vehicle passport (EVP) and in-vehicle display of environmental data and manipulation devices and manipulation strategies.

(3) The state of development of on-board sensors allows the continuous estimation of the emission rates of nitrogen oxides from light-duty vehicles. The emissions of other pollutants such as particulate matter can be reliably monitored by monitoring the integrity of particulate filters. It is therefore appropriate to set out requirements for OBM systems that include on-board sensors to assign a monitoring status to exhaust pollutants of interest to provide information to authorities about the functioning of emission control systems and the quality of exhaust emissions monitoring.

(4) For reasons of simplification and to achieve effective implementation of Regulation (EU) 2024/1257, it is appropriate to lay down rules specifying the general requirements for OBM and EEEDWS systems, OBFCM devices, EVP and in-vehicle display of environmental data laid down in that Regulation. Likewise, it is also appropriate to set out rules for the calculation of the OBM data parameters, for the on-board processing of OBM data, and for access to OBM data via the OBD port.

ELI: http://data.europa.eu/eli/reg_impl/2025/1707/oj 1/80EN OJ L, 5.9.2025

(5) To ensure that the measures used by OBM systems to induce repairs do not lead to road safety being endangered, it is appropriate that those systems use harmonised inducement methods.

(6) To ensure secure transmission of OBM data over the air, it is appropriate to allow manufacturers to use their own infrastructure and cybersecurity methods provided they comply with United Nations Regulation No 155(2).

(7) To ensure the submission of anonymous OBM data by vehicle manufacturers, it is appropriate to lay down requirements to that effect.

(8) To ensure that the anonymous OBM data transmitted to authorities is representative of the aggregate in-service emissions behaviour of vehicle types, it is appropriate to establish methods for the random sampling of OBM data to be transmitted over the air. Where the measures provided for in this Regulation entail the processing of personal data, that processing should be carried out in accordance with Regulations (EU) 2016/679(3)and (EU) 2018/1725(4)of the European Parliament and of the Council, as well as the relevant national law in accordance with those Regulations.

(9) To ensure effective implementation of OBM systems over the lifetime of vehicles placed on the market, specific requirements should be set out to address in-service conformity testing and market surveillance of such systems.

(10) Vehicles for which the OBM system has identified a potential malfunction or tampering should be considered to be in the process of being repaired. It is therefore appropriate to exclude such vehicles from certain aspects of in-service conformity testing.

(11) Requirements for OBM systems should adhere to the principle of technology neutrality where possible. It is therefore appropriate to lay down rules for the processing and transmission of OBM data which are broadly applicable to all powertrains, while recognising that certain OBM parameters may not be relevant to certain powertrains, for example, battery durability parameters for vehicles not equipped with a traction battery, or exhaust emission parameters for vehicles without an engine, and should not be processed in such cases.

(12) Certain OBM parameters that characterise the exhaust emissions of vehicles are also relevant to OBFCM devices. It is therefore appropriate to identify such parameters and to ensure they are transmitted by the vehicles using the data transmission methods envisaged for OBM systems, with a view to minimise the duplication of data that are transmitted over the air by OBM systems and OBFCM devices.

(13) The methods and administrative arrangements for the transmission of anonymous OBM data from manufacturers to authorities should be set out at a later stage of implementation. It is therefore appropriate to refer to these by using generic terms such as ‘authority server’ that do not prejudge the solutions that will be implemented.

(2) UN Regulation No 155 – Uniform provisions concerning the approval of vehicles with regards to cybersecurity and cybersecurity management system (OJ L 82, 9.3.2021, p. 30, ELI: http://data.europa.eu/eli/reg/2021/387/oj). In the case of a UN Regulation the series of amendments indicated reflects the version that has been published in the Official Journal of the European Union. Compliance with a series of amendments adopted after the particular series indicated shall be accepted as an alternative.

(3) Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data, and repealing Directive 95/46/EC (General Data Protection Regulation) (OJ L 119, 4.5.2016, p. 1, ELI: http://data.europa.eu/eli/reg/2016/679/oj).

(4) Regulation (EU) 2018/1725 of the European Parliament and of the Council of 23 October 2018 on the protection of natural persons with regard to the processing of personal data by the Union institutions, bodies, offices and agencies and on the free movement of such data, and repealing Regulation (EC) No 45/2001 and Decision No 1247/2002/EC (OJ L 295, 21.11.2018, p. 39, ELI: http://data.

2/80 ELI: http://data.europa.eu/eli/reg_impl/2025/1707/ojEN OJ L, 5.9.2025

(14) It is appropriate to specify the technical requirements so that vehicles make available information on their environmental performance through the EVP and, where appropriate, also by displaying relevant information inside the vehicle. The EVP should use technical solutions that ensure the interoperability with other digital product passports. To ensure the availability of information over time, EVP data should be made available by means of a QR code. The QR code acting as a data carrier for EVP data should respect the guidelines of ISO/IEC Standard 18004:2024.

(15) A robust framework for the prohibition of manipulation devices and manipulation strategies should ensure that the emissions behaviour of vehicles is not altered between compliance testing and real-world driving, and that data on sensors, fuel or electric energy consumption, electric range, and battery durability remains accurate and reliable. It is therefore appropriate to set out general and technical requirements, as well as specific documentation requirements, to implement the prohibition of manipulation devices and manipulation strategies, and to clarify the roles and responsibilities of manufacturers, type-approval authorities, market surveillance authorities, the Commission and recognised third parties.

(16) The measures provided for in this Regulation are in accordance with the opinion of the Technical Committee – Motor vehicles (TCMV),

and consists of the following three steps:

1.7.2. STEP 1: The following three parameters shall be calculated:

(a) ‘Cumulative NOx – 100 km’ (g) (parameter 1.19).

This parameter integrates the ‘tailpipe NOx mass flow’ (g/s).

The parameter shall have a resolution of 0,0001g or any smaller mass, a minimum value of zero and a maximum value of at least 100 000 g.

(b) ‘Cumulative fuel mass – 100 km’ (kg) (parameter 1.20).

This parameter integrates the ‘Engine fuel flow’ (g/s), with a conversion from the unit grams into kilograms.

The parameter shall have a resolution of 0,0000001 kg or any smaller mass, a minimum value of zero and a maximum value of at least 200 kg.

(c) ‘Cumulative distance – 100 km’ (km) (parameter 1.21).

This parameter integrates travelled distance by the vehicle.

The parameter shall have a resolution of 0,01 km or any smaller distance, a minimum value of zero and a maximum value of at least 100 km.

1.7.2.1. These parameters shall be continuously integrated, except when at least one of the following conditions apply:

(1) the engine is off;

(2) the time after first engine start during the OBM trip is less than 800 seconds;

(3) the parameter ‘Aftertreatment regeneration status’ (parameter 1.28) indicates that an active particulate filter regeneration is in progress;

(4) the ambient temperature is below -7 °C or above 38 °C;

(5) the vehicle speed is above 160 km/h;

(6) the altitude is above 1 300 m above mean sea level;

(7) a tracked auxiliary emission strategy (AES) monitored by OBM is active as defined in paragraph 2.8.2;

(8) when the vehicle is in a long cooldown phase;

(9) when at least one of ‘Monitoring status NOx’ or ‘Monitoring status generic’ is set to ‘Error’ or ‘Intermediate’.

In this case, these parameters shall also be reset to zero;

(10) when an input signal used to calculate any of the cumulated parameters above is deemed to be malfunctioning.

1.7.2.2. For the purposes of the integration of parameters 1.19 to 1.21, a ‘long cooldown phase’ shall be understood as

covering the following periods: — For a period of continuous idling, any period exceeding the first 180 seconds. — The first 180 seconds after the vehicle reaches a speed above 1 km/h following a continuous idling period exceeding 180 seconds.

— The first 180 seconds after a restart of the engine following a continuous engine-off period exceeding 180 seconds.

The following parameter shall be calculated:

Cumulative NO – 100 km ðgÞ NOx to fuel mass ratio ð0Þ¼ x Cumulative Fuel mass – 100 km ðkgÞ When ‘NO to fuel mass ratio (0)’ has been calculated, the parameters ‘Cumulative NO – 100 km’, ‘Cumulated fuel x x mass – 100 km’ and ‘Cumulated distance – 100 km’ shall all be reset to zero.

Prior to first calculation of each ‘NO to fuel mass ratio’ parameter since the manufacture of the vehicle, or if the x ‘NO to fuel mass ratio’ parameters are reset during a control unit reprogramming event, or by control unit x replacement, a default value of 0xFF for each data byte shall be used.

1.7.4. STEP 3:

The parameter ‘NOx to fuel mass ratio average’ (g/kg) (parameter 1.27) shall be calculated as follows:

1 i¼n – 1 NOx to fuel mass ratio average¼ n∑ i¼0 NOx to fuel mass ratio ðiÞ With n being the number of ‘NOx to fuel mass ratio (i)’ values not equal to 0xFFFF.

1.7.4.1. The parameters ‘Cumulative NOx – 100km’, ‘Cumulative fuel mass – 100 km’ and ‘Cumulative distance – 100km’ shall all be reset to zero, and the sequence is repeated from step 1.

1.7.4.2. The ‘NOx to fuel mass ratio (i)’ parameters and the ‘NOx to fuel mass ratio average’ parameter shall consist of 2 data bytes with a minimum value of zero and a maximum value of 200 g/kg.

7.3. Upon the conclusion of each OBM trip (trip end), the OBM system shall finalise the calculation and record all relevant trip parameters defined in Appendix 2.

7.4. The calculation of OBM trip data parameters may be omitted if any of the following conditions is met: — the ‘OBM trip distance’ (parameter 2.2) is less than 0,1 km at the end of the OBM trip. — the ‘OBM trip distance’ (parameter 2.2), ‘OBM trip time’ (parameter 2.3) or ‘Idle – time’ (parameter 2.4) reach their maximum values during the OBM trip.

— a new OBM trip is started before the calculation of trip data parameters and hashing of the OBM trip data have been completed.

7.5. When the calculation of OBM trip data parameters has not been completed, data from the trip may be discarded and not be stored on-board the vehicle. Data from discarded trips shall be included in the update of OBM lifetime parameters as defined in paragraph 7.7.

7.6. When the calculation of trip data parameters is complete, the OBM system shall hash the OBM trip data according to paragraph 9.6. The calculation of OBM trip data parameters and hashing of the OBM trip data shall be completed at the latest 10 seconds after the end of the OBM trip.

8.5.3. After verifying that the data package has been successfully stored in ‘OBM last transmission’ memory space, the OBM system shall clear the contents of the ‘OBM OTA outbox’.

8.6. OBM transmitted hash list

8.6.1. The ‘OBM transmitted hash list’ memory space shall store the ‘OBM transmission hash value’ parameter values from the 5 most recent transmitted ‘OBM OTA outbox’ data packages.

8.6.2. This memory space shall be managed on a rolling basis. When a new ‘OBM transmission hash value’ is added to the memory space, the oldest ‘OBM transmission hash value’ is deleted unless there are empty positions available.

8.6.3. Upon the successful transmission of the ‘OBM OTA outbox’, the OBM system shall save the ‘OBM transmission hash value’ in the ‘OBM transmitted hash list’.

8.6.4. By way of exemption from the reset conditions specified in the standards referred to in Part A, once the vehicle has entered into service, the content of the ‘OBM transmitted hash list’ shall be preserved as described in paragraph 6.9.

9. OBM data hashing

9.1. The OBM system shall apply the standard hash function described in paragraph 9.5. to compute the hash value of OBM trip data (according to paragraph 9.6.) and of the ‘OBM OTA outbox’ (according to paragraph 9.8.).

9.2. The OBM trip data hash value shall be used to select an OBM trip data package for later over-the-air transmission as defined in paragraph 9.7.

9.3. Hash values of ‘OBM OTA outbox’ data packages may be used to verify the integrity of the transmission of OBM data from vehicles to authorities.

9.4. Prior to hashing, OBM data must be structured according to the OBM data schemas provided in Appendix 7. For those data parameters defined within these OBM data schemas that are not applicable to the vehicle powertrain type, the OBM system shall fill each unused data byte with a default value of 0xFF.

9.5. OBM hash function

9.5.1. The OBM system shall implement a SHA-256 hashing process to support the hashing operations specified in this Annex. All hashing operations shall be carried out on-board the vehicle in compliance with internationally recognised cryptographic standards to ensure cryptographic robustness, data integrity, and resistance to unauthorised manipulation.

9.6. OBM trip data hashing

9.6.1. Following the calculation of OBM trip data parameters according to paragraph 7.2, the contents of the OBM trip data shall be hashed based on the OBM trip data schema layout specified in Appendix 7 for bytes 0 through to byte

58. The hash function shall be applied to OBM trip data on-board the vehicle only once. After calculation of the hash value for the OBM trip data, no modifications to the OBM trip data package shall be allowed. The ‘OBM trip hash validity status’ byte and ‘OBM trip hash value’ parameter shall not be included in the computation of the hash value.

9.6.2. All reserved data bytes shall be filled with zero values unless otherwise specified.

9.6.3. After calculation of the hash value for the OBM trip data, no modifications to the OBM trip data shall be allowed.

9.6.4. The resulting hash value shall be truncated, preserving the most significant 4 bytes.

9.6.5. Until the hash function computation is finalised, the ‘OBM trip hash value’ parameter shall store a placeholder value of 0xFFFFFFFF and, the ‘OBM trip hash validity status’ shall indicate the hash function computation is incomplete as defined in paragraph 2.9.3.

9.6.6. Once the hash computation is complete, the ‘OBM trip hash value’ shall be updated with the truncated hash value, and the ‘OBM trip hash validity status’ shall be set to indicate the computation of the ‘OBM trip hash value’ is complete. The completed OBM trip data together with the ‘OBM trip hash value’, in the layout specified in Appendix 7, shall be referred to as the OBM trip data package.

9.7. Criterion for OBM trip data selection for later over-the-air transmission (hash condition)

9.7.1. The criterion for OBM trip data package selection for later over-the-air transmission shall be based on the value of the least significant byte of the resulting, truncated ‘OBM trip hash value’. If this value is equal to either 00, 40, 80, or C0, the hash condition shall be considered as fulfilled.

9.7.2. Following the OBM trip data hashing according to paragraph 9.6, the OBM system shall determine whether the ‘OBM trip hash value’ satisfies the hash condition. If the condition is satisfied, the OBM trip data package is selected for OTA transmission.

9.8. OBM OTA outbox hashing

9.8.1. The contents of the ‘OBM OTA outbox’ shall be hashed based on the OBM OTA outbox data schema layout specified in Appendix 7 for bytes 0 through to byte [679]. The hash function shall be applied to the contents of the OBM OTA outbox on-board the vehicle only once. After calculation of the hash value for the OBM OTA outbox, no modifications to the OBM trip data package shall be allowed. The ‘OBM transmission hash validity status’ byte and ‘OBM transmission hash value’ parameter shall not be included in the computation of the hash value.

9.8.2. The resulting hash value shall not be truncated and shall be stored in its full length of 32 bytes.

9.8.3. Until the hash computation is finalised, the ‘OBM transmission hash value’ parameter shall store a placeholder value with each data byte set to a value of 0xFF and the ‘OBM trip hash validity status’ shall indicate the hash function computation is incomplete as defined in paragraph 4.4.

ELI: http://data.europa.eu/eli/reg_impl/2025/1707/oj 25/80EN OJ L, 5.9.2025

9.8.4. Once the hash computation is complete, the ‘OBM transmission hash value’ shall be updated with the calculated hash value, and the ‘OBM transmission hash validity status’ shall be set to indicate the computation of the ‘OBM transmission hash value’ is complete. The completed ‘OBM OTA outbox’ together with the ‘OBM transmission hash value’, in the layout specified in Appendix 7, shall be referred to as the ‘OBM OTA outbox’ data package.

ELI: http://data.europa.eu/eli/reg_impl/2025/1707/oj 49/80EN OJ L, 5.9.2025 ANNEX II DRIVER WARNINGS AND INDUCEMENT METHODS OF THE EXCESS EXHAUST EMISSIONS DRIVER WARNING SYSTEM

1. Introduction

1.1. This annex sets out the requirements for driver warnings and inducement method applicable to the excess exhaust emissions driver warning system (EEEDWS). Illustrative schematic diagrams are provided in Appendix 1 to this Annex.

2. Driver warning and inducement method requirements

2.1. The driver warnings and inducement methods shall be initiated as soon as at least one of the monitoring statuses of exhaust emissions referred to in Article 5 is set to ‘Error’ and remain active until none of the monitoring statuses are set to ‘Error’.

2.2. Counters

2.2.1. The EEEDWS shall include the counters described in paragraphs 2.2.3 to 2.2.8 to support the operation of the driver warnings and inducement methods.

2.2.2. Further technical specifications of the counters are described in the relevant tables of Annex I.

2.2.3. ‘OBM warning distance’ counter

2.2.3.1. If any of the monitoring statuses of exhaust emissions is set to ‘Error’, the ‘OBM warning distance’ counter shall increment by a value of 0,1 for every 0,1 kilometres driven with the internal combustion engine running, to record the distance travelled by the vehicle in kilometres since the initiation of the driver warnings.

2.2.3.2. The ‘OBM warning distance’ counter shall have a resolution of 0,1 km or any smaller distance, a minimum value of 0 km and a maximum value of at least 6 553,5 km.

2.2.3.3. While all monitoring statuses of exhaust emissions have a continuous status other than ‘Error’, the ‘OBM warning distance’ counter may decrement as follows: — if the ‘OBM warning distance’ counter has a value greater than 400 km, the counter may decrement by the distance driven in kilometres with the internal combustion engine running, — if the ‘OBM warning distance’ counter has a value equal to or lower than 400 km, the counter may decrement by up to 100 km for each accumulated 100 km distance driven with the internal combustion engine running.

2.2.3.4. The ‘OBM warning distance’ counter may reset under the following conditions: — if any of the monitoring statuses of exhaust emissions is reset using a generic scan tool or service tool, the ‘OBM warning distance’ counter shall reset to 2 400 km or the value at the time of reset, whichever is lower, — the ‘OBM warning distance’ counter may reset to zero at the end of a valid OBM trip following a minimum accumulated distance driven with the internal combustion engine running of 400 km while all monitoring statuses of exhaust emissions have a continuous status other than ‘Error’.

50/80 ELI: http://data.europa.eu/eli/reg_impl/2025/1707/ojEN OJ L, 5.9.2025

2.2.3.5. If the ‘OBM warning distance’ counter reaches its maximum value, it shall freeze until one of the conditions to decrement or reset are met.

2.2.4. ‘OBM warning distance – lifetime’ counter

2.2.4.1. If, during the vehicle lifetime, any of the monitoring statuses of exhaust emissions is set to ‘Error’, the ‘OBM warning distance – lifetime’ counter shall record the distance travelled with any of the monitoring statuses of exhaust emissions in ‘Error’ and the internal combustion engine running.

2.2.4.2. The ‘OBM warning distance – lifetime’ counter shall have a resolution of 1 km, a minimum value of 0 km and a maximum value of 65 535 km.

2.2.4.3. The ‘OBM warning distance counter – lifetime’ shall not reset to zero, and when it reaches its maximum value, it shall freeze.

2.2.5. ‘OBM distance since monitoring status reset’ counter

2.2.5.1. The ‘OBM distance since monitoring status reset’ counter indicates the distance travelled with the internal combustion engine running since none of the monitoring statuses of exhaust emissions were last set to ‘Error’.

2.2.5.2. The ‘OBM distance since monitoring status reset’ counter shall have a resolution of 1 km or any smaller distance, a minimum value of 0 km and a maximum value of at least 65 535 km.

2.2.5.3. The ‘OBM distance since monitoring status reset’ counter shall reset to zero when one of these conditions is met: — any of the monitoring statuses of exhaust emissions transition from ‘Error’ to either ‘Normal’ or ‘Intermediate’ status resulting in all monitoring statuses of exhaust emissions having a ‘Normal’ or ‘Intermediate’ status, — the monitoring statuses of exhaust emissions are reset using a generic scan tool or service tool.

2.2.5.4. If the ‘OBM distance since monitoring status reset’ counter reaches its maximum value, it shall freeze until one of the conditions to reset to zero is met.

2.2.6. ‘OBM monitoring status reset – lifetime’ counter

2.2.6.1. The ‘OBM monitoring status reset – lifetime’ counter shall count the number of times that any command to reset monitoring statuses or clear OBM data is received from a generic scan tool or service tool during the vehicle’s lifetime. This counter shall be an integer with a minimum value of 0 and a maximum value of 65 535. If the ‘OBM monitoring status reset – lifetime’ counter reaches its maximum value, it shall freeze and not reset to zero.

2.2.6.2. If the monitoring statuses of exhaust emissions are reset as part of a manufacturer software update, it shall not be required to increment the ‘OBM monitoring status reset – lifetime’ counter.

2.2.7. ‘OBM current inducement distance’ counter

2.2.7.1. The ‘OBM current inducement distance’ counter shall count the distance driven in kilometres with the internal combustion engine running since the current or last inducement period began as described in paragraph 2.4.2.

ELI: http://data.europa.eu/eli/reg_impl/2025/1707/oj 51/80EN OJ L, 5.9.2025

2.2.7.2. The ‘OBM current inducement distance’ counter shall have a resolution of 0,1 km or any smaller distance, a minimum value of 0 km and a maximum value of at least 6 553,5 km. If the counter reaches its maximum value, it shall freeze and not reset.

2.2.7.3. If the inducement period is paused as described in paragraph 2.4.3, the ‘OBM current inducement distance’ counter shall freeze.

2.2.7.4. The ‘OBM current inducement distance’ counter shall reset to zero when one of the following conditions is met: — the inducement system is activated as defined in paragraph 2.4, — the monitoring statuses of exhaust emissions are reset using a generic scan tool or service tool.

2.2.8. ‘OBM inducement distance – lifetime’ counter

2.2.8.1. The ‘OBM inducement distance – lifetime’ counter shall count the distance driven in kilometres with the internal combustion engine running during the vehicle lifetime while inducement is active.

2.2.8.2. The ‘OBM inducement distance – lifetime’ counter shall have a resolution of 1 km, a minimum value of 0 km and a maximum value of 65 535 km. If the counter reaches its maximum value, it shall freeze and not reset.

2.2.8.3. If the inducement period is paused or reset as described in paragraph 2.4.3 the ‘OBM inducement distance – lifetime’ counter shall freeze until conditions to increment are met.

2.3. Driver warnings

2.3.1. General requirements for the display of driver warnings

2.3.1.1. The EEEDWS shall include a warning system consisting of visual alarms to inform the driver when faults or tampering that prevent adequate emissions control or adequate performance of the OBM system have been identified. The warning system may also include an audible component to alert the driver.

2.3.1.2. A facility to permit the driver to dim the visual warnings and mute the audible component of the warning system may be provided on vehicles designed and constructed for use by the rescue services, armed services, civil defence, fire services and forces responsible for maintaining public order.

2.3.1.3. If any of the monitoring statuses of exhaust emissions is set to ‘Error’, the MI as defined in UN Regulation No 154, Annex C5, shall be continuously activated, and an appropriate driver warning shall be displayed according to paragraphs 2.3.2, 2.3.3 and 2.3.4. The driver warning displayed shall be sufficiently clear for the driver to understand that faults or tampering that prevent adequate emissions control or monitoring and justify a repair have been identified by the OBM system. The driver warning shall also indicate the remaining distance until the repair inducement will be activated.

2.3.1.4. The driver warnings may be temporarily interrupted as required to display important safety and other emissions control system related warnings to the driver.

52/80 ELI: http://data.europa.eu/eli/reg_impl/2025/1707/ojEN OJ L, 5.9.2025

2.3.1.5. When an OBM driver warning coincides with the continuous warning described in paragraph 3.4 of Appendix 6 of UN Regulation No 154, both driver warnings may be displayed simultaneously to the driver, if possible. If simultaneous display of the driver warnings is not possible, the driver warnings shall be suppressed temporarily for the duration of the continuous warning and the ‘OBM warning distance’ shall be managed according to the

following rules: — For values of the ‘OBM warning distance’ at time of driver warning suppression between 0 and 1 400: At the end of the continuous warning described in paragraph 3.4 of Appendix 6 of UN Regulation No 154, reset the ‘OBM warning distance’ to 1 400 km or the value at the time of reset, whichever is lower, — For values of the ‘OBM warning distance’ at time of driver warning suppression between 1 400 and 2 400:

At the end of the continuous warning described in paragraph 3.4 of Appendix 6 of UN Regulation No 154, manufacturers may reset the ‘OBM warning distance’ to a minimum of 2 350 km. For values of the ‘OBM warning distance’ above 2 400 before inducement has started: Reset and freeze the ‘OBM warning distance’ to 2 400 km for the duration of the continuous warning described in paragraph 3.4 of Appendix 6 of UN Regulation No 154.

2.3.2. Low-level warning

2.3.2.1. When the ‘OBM warning distance’ counter value is lower than 1 400 km and any of the monitoring statuses of exhaust emissions is set to ‘Error’, the driver warnings shall be displayed for a sufficient period upon activation of the powertrain.

2.3.3. Delayed activation of the MI and display of the driver warnings.

2.3.3.1. Without prejudice to other criteria for MI activation, while the ‘OBM warning distance’ counter described in paragraph 2.2.3 has a value lower than 400 km, manufacturers may delay activation of the MI, as specified in paragraph 2.3.1, and the display of the low-level warning, as specified in paragraph 2.3.2. If the ‘OBM warning distance’ counter reaches a value of 400 km while the activation of MI and display of warnings are delayed, the low-level warning shall be displayed to the driver without waiting until the next activation of the powertrain.

2.3.3.2. When the ‘Level 2 – Possible tampering detected’ status is set in the ‘Tampering status’ parameter as defined in Annex I, paragraph 1.10, the delayed activation of the MI and display of the driver warnings shall not be permitted.

2.3.4. High-level warning

2.3.4.1. When the ‘OBM warning distance’ counter value is equal to or greater than 1 400 km and the inducement method is not yet activated and any of the monitoring statuses of exhaust emissions is set to ‘Error’, a driver warning shall be persistently displayed.

2.3.5. Inducement method warning

2.3.5.1. When the inducement method is activated as described in paragraph 2.4, a driver warning shall be continuously displayed and clearly indicate that the repair inducement system is active. The warning shall also indicate the number of remaining restarts or the remaining distance before engine start is prohibited, depending on the type of inducement method installed.

2.3.5.2. When the repair inducement warning period has expired, a clear continuous warning indicating engine starts are prohibited shall be displayed.

2.3.6. Suppression of the driver warnings following a monitoring status update

2.3.6.1. Without prejudice to other criteria for MI activation, if the driver warning system has been activated as described in paragraphs 2.3.1 to 2.3.4 and all monitoring statuses of exhaust emissions that were set to ‘Error’ have transitioned to ‘Normal’ or ‘Intermediate’, the driver warnings and MI activation may be suppressed at the start of the next OBM trip.

ELI: http://data.europa.eu/eli/reg_impl/2025/1707/oj 53/80EN OJ L, 5.9.2025

2.4. Inducement method to facilitate repairs

2.4.1. General requirements of inducement method to facilitate repairs

2.4.1.1. The vehicle shall be equipped with an inducement method to ensure appropriate repairs to emissions control systems are carried out when faults or tampering that prevent adequate emissions control or monitoring and justify a repair have been identified by the OBM system.

2.4.1.2. The inducement method shall be designed to ensure the vehicle cannot be operated using its engine if the sequence of driver warnings is ignored. Hybrid vehicle operation in zero-emission mode may remain unrestricted during active inducement.

2.4.1.3. The requirement for the inducement method shall not apply to vehicles designed and constructed for use by the rescue services, armed services, civil defence, fire services and forces responsible for maintaining public order.

Permanent deactivation of the driver inducement system for these vehicles shall only be done by the vehicle manufacturer.

2.4.2. Activation of the inducement method

2.4.2.1. An inducement method in accordance with point 2.4.4 shall be activated at the start of the next OBM trip following the warning distance counter exceeding 2 400 km, provided any of the monitoring statuses remains in ‘Error’.

2.4.3. Pausing and deactivation of the inducement method following a monitoring status update

2.4.3.1. If, after the inducement method was activated, all the monitoring statuses in ‘Error’ have transitioned to ‘Normal’ or ‘Intermediate’, the countdown of distance or number of engine starts may be paused and the driver warning may be hidden as long as all monitoring statuses are not in ‘Error’.

2.4.3.2. If the ‘OBM warning distance’ counter decrements to a value less than 2 400 km, the inducement method may be deactivated at the start of the next OBM trip.

2.4.4. Manufacturer options for inducement methods

2.4.4.1. The manufacturer shall select one option of inducement methods to install from those described in paragraphs

2.4.4.2 to 2.4.4.5.

2.4.4.2. Option A – no engine starts after maximum number of engine starts

2.4.4.2.1. This option allows a countdown of engine starts remaining once the inducement system activates. Engine restarts shall be prevented at the start of the next new OBM trip after the number of engine restarts performed since activation of inducement reaches a maximum value of no more than 20. Engine starts initiated by the vehicle control system, such as start-stop systems, or engine restarts resulting from an engine stall condition shall not be included in this countdown.

2.4.4.3. Option B – no engine starts after remaining distance

2.4.4.3.1. This option allows a countdown of distance once the inducement system starts. Engine restarts shall be prevented at the next new OBM trip after the vehicle has driven, with the engine running, a maximum distance of no more than the average driving range of one full tank of fuel since the activation of the repair inducement.

Engine restarts initiated by the vehicle control system, such as start-stop systems, or engine restarts resulting from an engine stall condition shall be permitted after maximum distance has been exceeded. The average driving range of one full fuel tank shall be derived from the fuel consumption as determined from a Type 1 test.

54/80 ELI: http://data.europa.eu/eli/reg_impl/2025/1707/ojEN OJ L, 5.9.2025

2.4.4.4. Option C – no engine start after refuelling

2.4.4.4.1. This option results in a vehicle being unable to start after re-fuelling if the inducement system has activated.

2.4.4.5. Option D – fuel lockout

2.4.4.5.1. This option prevents the vehicle from being refuelled by locking the fuel filler system after the inducement system activates. The lockout system shall be robust to prevent it being tampered with.

2.4.5. Reactivation of inducement after failed repair

2.4.5.1. After a repair has been carried out to correct a fault where the OBM system has activated the inducement method as defined in paragraph 2.4.2 and engine start has been inhibited, the inducement method may be deactivated by a generic scan tool or service tool to enable the vehicle to be restarted.

2.4.5.2. The vehicle shall operate for a maximum of 400 km with the internal combustion engine running, distributed over several OBM trips, or a single OBM trip exceeding 400 km to enable the success of the repair to be validated. If the monitoring status of any exhaust emissions resets to ‘Error’ during the validation period, the ‘OBM warning distance’ counter shall reset to 2 401 km and the inducement system shall be activated at the start of the next OBM trip.

2.4.5.3. After reactivation of the inducement system, the maximum number of engine starts permitted shall be limited to no more than 3. Engine starts initiated by the vehicle control system, such as start-stop systems, or engine restarts resulting from an engine stall condition shall not be included in this countdown.

2.5. Information requirements

2.5.1. The manufacturer shall deliver new vehicles with clear information in user manuals or other appropriate means to ensure that vehicle users are aware of the functionality of driver warnings and inducement methods of the excess exhaust emissions driver warning system.

64/80 ELI: http://data.europa.eu/eli/reg_impl/2025/1707/ojEN OJ L, 5.9.2025 ANNEX IV METHODS FOR IN-SERVICE CONFORMITY CHECKS AND MARKET SURVEILLANCE OF OBM SYSTEMS This Annex sets out the in-service conformity (ISC) methodology for checking the conformity of the NOx and PM emissions monitoring performed by OBM systems, and market surveillance methods for the verification of compliance with the general requirements of OBM systems.

PART A In-service conformity checks of OBM systems

1. INTRODUCTION

1.1. In-service conformity checks of OBM systems shall ensure that the OBM system present in a sample of vehicles belonging to the same OBM family as defined in point 2 performs calculations of distance-specific emissions of NOx with reasonable accuracy and that no systematic underestimation of emissions occurs.

1.2. In-service conformity checks shall also ensure that OBM systems are capable of detecting exceedances of at least 2,5 times the relevant exhaust emission limit values set out in Annex I of Regulation (EU) 2024/1257 for both NOx and PM.

1.3. In-service conformity checks shall be performed by vehicle manufacturers and granting type-approval authorities.

1.4. In-service conformity checks may be performed by the Commission and recognised third parties.

1.5. In-service conformity checks shall have no minimum frequency requirements.

2. OBM FAMILY DEFINITION

2.1. For the purposes of in-service conformity testing of OBM systems, an OBM family shall consist of vehicles that are covered by the same declaration of compliance in accordance with Annex III.

3. VEHICLE SELECTION CRITERIA AND ELIGIBILITY FOR TESTING

3.1. The granting type-approval authority and other relevant entities shall collect necessary information to determine which OBM families to check. Anonymous OBM data submitted by manufacturers to authorities according to Article 11 shall be considered.

3.2. In-service conformity checks of OBM systems shall be performed for a period of up to 200 000 km or 10 years, whichever comes first.

3.3. In addition to the eligibility criteria for in-service conformity checks from Article 14, the applicable technical vehicle selection criteria will be those laid out in Annex II to Implementing Regulation (EU) 2025/1706.

4. OBM IN-SERVICE CONFORMITY TESTS

4.1. The in-service conformity checks of OBM systems shall be performed by means of a laboratory or on-road emissions test. For on-road tests with PEMS equipment, the validation procedure laid down in Annex 6 of UN Regulation No 168 shall be followed.

4.2. The tests shall be performed in such a manner that the emissions and distances covered by the emissions test and the corresponding OBM trip are the same.

ELI: http://data.europa.eu/eli/reg_impl/2025/1707/oj 65/80EN OJ L, 5.9.2025

4.3. The checks shall be performed on a sample of vehicles belonging to the same OBM family, and the results shall be evaluated according to the evaluation method described in paragraph 5. Each vehicle tested shall contribute, at most, two results to the verification described in paragraph 5.1 and two results to the verification described in paragraph 5.2 (one result for PM and one result for NOx).

4.4. In-service conformity checks of OBM systems shall be conducted in parallel with the ISC tests for verifying compliance with tailpipe emission limits, as outlined in Annex II to Implementing Regulation (EU) 2025/1706 The same emissions test (RDE or Type 1) shall support both testing methodologies.

4.5. As an alternative method, the in-service conformity checks of OBM systems according to paragraph 1.1 may be performed using any on-road trip longer than 40 minutes and 20 kilometres which complies with the ambient and dynamic trip conditions laid down in points 8.1 and 8.2 of UN Regulation No 168, with a maximum speed of 160 km/h. If a part of the test or the entire test is performed outside of extended conditions, or if the maximum speed is exceeded, the test shall be considered invalid.

4.6. A vehicle with at least one monitoring status of exhaust emissions set to ‘Intermediate’ prior to testing shall undergo a pre-conditioning procedure. During this pre-conditioning, the vehicle shall be driven for at least 40 minutes and 20 kilometres with the internal combustion engine running. The pre-conditioning shall include at least 5 consecutive minutes in which the vehicle shall be driven with a velocity of 90 km/h or higher. After preconditioning, the powertrain shall be deactivated, and all the monitoring statuses of exhaust emissions shall be read. Vehicles shall be eligible for ISC testing if none of the monitoring statuses is set to ‘Error’.

4.7. A vehicle with an ‘OBM distance since monitoring status reset’ (parameter 1.51 of Annex I) value of less than 400 km shall undergo pre-conditioning as described in paragraph 4.6 until this parameter exceeds 400 km.

5. EVALUATION OF TEST RESULTS

5.1. The results of the emissions test shall be used to check the accuracy of the calculation of distance-specific exhaust emissions of NOx performed by the OBM system according to Article 6.

5.2. If the results of the emission test are equal or greater than 2,5 times the relevant exhaust emission limit values set out in Annex I of Regulation (EU) 2024/1257 for either NOx or PM, the results of the emissions test shall be used to verify that the OBM system can detect such exceedances. This verification shall not apply to tests performed using the alternative method described in paragraph 4.6.

5.3. At the end of the emissions test, the value reported by the OBM system for the ‘Distance-specific NOx’ for the OBM trip (parameter 2.5 of Annex I) and the distance-specific NOx emissions value for the trip as measured by the emissions laboratory or PEMS equipment shall be recorded and compared.

5.4. The distance-specific NOx emissions value for the trip as measured by PEMS equipment shall be calculated by dividing the cumulated NOx mass emissions over the trip by the total trip distance. The PEMS margin correction from paragraph 4 of Annex 11 to UN Regulation No 168 and the corrections from paragraph 5 of Annex 7 to the same Regulation shall apply.

5.5. Neither the value from the OBM system nor the value measured by the emissions laboratory or PEMS equipment shall be modified by any other correcting factors.

6. STATISTICAL PROCEDURE FOR OBM IN-SERVICE CONFORMITY

6.1. Prior to the performance of the first OBM ISC test for an OBM family, the manufacturer, accredited laboratory or technical service (‘party’) shall notify the intent of performing in-service conformity testing of a given OBM family to the granting type-approval authority. Upon this notification, the granting type-approval authority shall open a new statistical folder to process the results for the OBM family to process the results for that particular party or that pool of parties.

66/80 ELI: http://data.europa.eu/eli/reg_impl/2025/1707/ojEN OJ L, 5.9.2025

6.2. Test results from two or more accredited laboratories or technical services may be pooled for the purposes of a common statistical procedure.

6.3. The pooling of test results shall require the written consent from all the interested parties providing test results to a pool of results, and a notification to the granting type-approval authority prior to the start of testing.

6.4. One of the parties pooling test results shall be designated as leader of the pool and be responsible for data reporting and communication with the granting type-approval authority.

6.5. The sample size in a statistical folder shall be ten vehicles.

7. COMPLIANCE ASSESSMENT

7.1. The decision regarding the compliance of an OBM family according to paragraphs 1.1 and 1.2 shall be made according to Appendix 1.

7.2. The decision regarding the compliance of an OBM family according to paragraph 1.1 shall be made every time that the sample size is reached, and the number of vehicles in the sample shall be reset to zero thereafter.

7.3. The decision regarding the compliance of an OBM family according to paragraph 1.2 shall be made when the emissions test result is equal or greater than 2,5 times the applicable emission limit for PM or NOx.

7.4. The durability multipliers for adjusting exhaust emission limits under Annex 1 of Regulation (EU) 2024/1257 shall apply during additional lifetime.

8. REPORTING, CORRECTIVE AND ADMINISTRATIVE MEASURES

8.1. If an OBM family is found to be non-compliant, type-approval authorities shall require the manufacturer to take measures in accordance with Chapter XI of Regulation (EU) 2018/858. The granting type-approval authority may extend the investigations to vehicles in service of the same manufacturer belonging to other ISC families with the same OBM system which are likely to be affected by the same non-compliance.

8.2. The OBM system compliance testing shall be part of the annual report by the granting type-approval authority.

11. COMPLIANCE ASSESSMENT

11.1. Market surveillance authorities shall perform an assessment of compliance of vehicles with the general requirements of OBM systems and of the EEEDWS.

11.2. As part of this verification of general requirements, market surveillance authorities shall verify the integrity of OBM data from its production to its submission by the vehicle manufacturer. This verification may be performed by tracing OBM datasets from selected test trips by means of their hash values, or through other appropriate methods.

12. REPORTING, CORRECTIVE AND ADMINISTRATIVE MEASURES

12.1. If an OBM family is found to be non-compliant, market surveillance authorities shall proceed in accordance with

Chapter XI of Regulation (EU) 2018/858.

12.2. The market surveillance authority may extend the investigations to vehicles in service of the same manufacturer belonging to other OBM families with the same OBM system which are likely to be affected by the same non- compliance.

68/80 ELI: http://data.europa.eu/eli/reg_impl/2025/1707/ojEN OJ L, 5.9.2025 Appendix 1 Compliance criteria for an OBM family

1. Compliance criteria according to Part A, paragraph 1.1 Where 10 pairs of a distance-specific NOx emissions value from an emission test and a ‘Distance-specific NOx’ value for the corresponding OBM trip are available, the compliance of the OBM family with the accuracy requirements for the calculation of distance-specific exhaust emissions of NOx can be established based on the differences between the pairs.

If an emissions test result is equal or greater than 2,5 times the applicable emission limit for PM or NOx, or if the OBM monitoring status for NOx (parameter 1.47) changes to ‘Error’ following the test, the distance-specific NOx emissions value from such emission test and the ‘Distance-specific NOx’ value for the corresponding OBM trip shall not count toward the 10 pairs for the calculation of compliance criteria described in this paragraph.

Δ shall be calculated as the average difference between the distance-specific NOx emissions from emissions test results (NOx )and the ‘Distance-specific NOx’ for the OBM trip (NOx ) for all valid tests:

emissions,i OBM,i 1 10 Δ¼ 10∑ i¼1ðNOx emissions;i – NOx OBM;iÞ σ shall be calculated as the root-mean-square of the differences over all tests: qffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffi 1 10 2 σ¼ 9 ∑ i¼1ðNOx emissions;i – NOx OBM;iÞ

The OBM family shall be compliant in the following cases: — If Δ is equal or smaller than zero. — If Δ is greater than zero but smaller than 30 % of the applicable NOx limit, and σ is less than 50 % of the applicable NOx limit.

In any other case, the OBM family shall be non-compliant, and the procedure of paragraph 7 shall apply.

2. Compliance criteria according to Part A, paragraph 1.2 If the emissions test result is equal or greater than 2,5 times the applicable emission limit for PM or NOx, specific compliance criteria shall apply based on the results of the single test. The results from such tests shall not be considered for compliance according to Part A, paragraph 1.1.
