OJ L, 5.9.2025
(3) UN Regulations(3), notably UN Regulation No 154(4), UN Regulation No 168(5) and UN Regulation No 83(6) are
referred to in this Regulation only in the context of emission type-approval for light-duty vehicles that is covered by
Article 14(8)(a) and (b) of Regulation (EU) 2024/1257. Testing procedures, methodologies and procedures, tests and
checks that are included in the above-mentioned UN Regulations and relate to M and N vehicles shall be adopted
2 2
subsequently under Article 14(9)(a) and (b) of Regulation (EU) 2024/1257.
(4) In order to integrate internationally harmonised technical rules into the emission type-approval system, references
should be made to UN Regulation No 154 in accordance with the requirements set out in Table 1 of Annex III to
Regulation (EU) 2024/1257 regarding test conditions and administrative provisions that apply to emissions type-
approval under laboratory exhaust emission measurement, but also for Model Information Document, Model of
Emission Type-Approval certificate and test report ensuring that emission type-approval specificities are set out.
References should be made to UN Regulation No 168 in accordance with requirements set out in Table 1 of
Annex III to Regulation (EU) 2024/1257 regarding test conditions and administrative provisions that apply to
Emissions type-approval under Real Driving Emission (RDE), adding requirements that comply with specific
provisions of Regulation (EU) 2024/1257 regarding exhaust PN emissions. Where appropriate, reference should
10
also be made to UN Regulation No 83 regarding the measurement of crankcase gases, the emissions at low ambient
temperature and the in-service conformity methodology. Additionally, UN Regulation No 155(7)should be referred
to for cybersecurity measures and to ensure the secure transmission of data related to emissions.
(5) In order to reflect the average expected lifetime of vehicles in the Union, the tests, methods and procedures should
include specific requirements to comply with the durability requirements of vehicles, systems, components and
separate technical units under Regulation (EU) 2024/1257, more particularly under Annex IV thereto.
(6) Effective implementation is ensured by setting out roles and responsibilities of respectively manufacturers, Member
States type-approval authorities and national authorities, and recognised third parties in accordance with Annex V
to Regulation (EU) 2024/1257 for applicable tests and procedures. When required, templates for declaration of
compliance shall be made available to manufacturers in accordance with the provisions of Annex V to Regulation
(EU) 2024/1257, in particular for specific tests applying to (i) crankcase emissions (Type 3 test); (ii) durability of
emission control system (Type 5 test); (iii) OBD requirements for the purposes of emission type-approval; (iv) anti-
tampering, security and cybersecurity requirements; (v) regeneration; (vi) correct operation of systems using a
consumable reagent and pollution control devices; (vii) CO ambient temperature correction (ATCT); and (viii)
2
geofencing technologies, where applicable.
(3) 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. Supplements to the series of amendments indicated in the Official Journal publication shall apply irrespective of
publication in the Official Journal of the European Union. New series of amendments adopted after the series of amendments indicated in
the Official Journal publication shall be accepted as an alternative.
(4) UN Regulation No 154 – Uniform provisions concerning the approval of light duty passenger and commercial vehicles with regards to
criteria emissions, emissions of carbon dioxide and fuel consumption and/or the measurement of electric energy consumption and
electric range (WLTP), 02 series of amendments (OJ L, 2022/2124, 10.11.2022, ELI: http://data.europa.eu/eli/reg/2022/2124/oj).
(5) UN Regulation No 168 – Uniform provisions concerning the approval of light duty passenger and commercial vehicles with regards to
real driving emissions (RDE) [2024/211] (OJ L, 2024/211, 12.1.2024, ELI: http://data.europa.eu/eli/reg/2024/211/oj).
(6) UN Regulation No 83 – Uniform provisions concerning the approval of vehicles with regard to the emission of pollutants according to
engine fuel requirements (OJ L, 2024/1312, 27.6.2024, ELI: http://data.europa.eu/eli/reg/2024/1312/oj).
(7) UN Regulation No 155 – Uniform provisions concerning the approval of vehicles with regards to cyber security and cyber security

2/107 ELI: http://data.europa.eu/eli/reg_impl/2025/1706/ojEN
OJ L, 5.9.2025
(7) In order to ensure that the required type-approval information is consistently presented and for effective
implementation as well as increased transparency, the emission type-approval certificate numbering system should
be adapted to Regulation (EU) 2024/1257 requirements for applicable tests and procedures, ensuring a harmonised
presentation. Templates for type-approval certificates and templates for certificates of conformity should be adapted
where necessary and Commission Implementing Regulation (EU) 2020/683(8)should be amended accordingly.
(8) In order to comply with the obligation provided for in Article 14(7) of Regulation (EU) 2024/1257 that for vehicle
types of categories M and N , the methods for measuring pollutant exhaust emissions and evaporative emissions
1 1
are to reflect those laid down in Commission Regulation (EU) 2017/1151(9), the relevant methods, requirements
and procedures should be specified in accordance with that requirement, notably for the Type 1 test, Type 3 test,
Type 4 test, Type 5 test, Type 6 test and OBD requirements.
(9) The use of manipulation devices or manipulation strategies is prohibited under Regulation (EU) 2024/1257. Ensuring
an effective implementation and enforcement of such prohibition is essential to safeguard the objectives of that
Regulation. Specific methods, procedures, administrative procedures, reporting and documentation obligations
should therefore be set out for establishing the absence of manipulation devices and manipulation strategies related
to exhaust and evaporative emissions.
(10) 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.
(11) At market surveillance stage, screening tests for the presence of manipulation devices and manipulation strategies
related to exhaust and evaporative emissions should focus on identifying situations where the vehicle detects test
conditions followed by a change in the emissions control strategy and emissions behaviour that is not documented
at type-approval. For the effective performance of such screening tests and assessment, it is appropriate that market
surveillance authorities performing such tests should use a variety of testing approaches, and be able to evaluate the
results of the screening by comparing them not to the emission limits set out in Annex I to Regulation
(EU) 2024/1257, but to specific thresholds based on technical considerations.
(12) In order to ensure that the required type-approval information is consistently reflected, new examples for the Euro 7
type-approval related certificate numbering system should be introduced. For effective implementation, such as for
registration purposes, the templates for the certificates of conformity should be adapted where necessary. Regulation
(EU) 2020/683 should be amended accordingly.
(13) In order to provide approval authorities, market surveillance authorities and registration authorities of the Member
States and the manufacturers with sufficient time to implement this Regulation regarding Certificate of Conformity,
the date of application of Annex XVIII should be deferred.
(8) Commission Implementing Regulation (EU) 2020/683 of 15 April 2020 implementing Regulation (EU) 2018/858 of the European
Parliament and of the Council with regards to the administrative requirements for the approval and market surveillance of motor
vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles (OJ L 163, 26.5.2020,
p. 1, ELI: http://data.europa.eu/eli/reg_impl/2020/683/oj).
(9) Commission Regulation (EU) 2017/1151 of 1 June 2017 supplementing Regulation (EC) No 715/2007 of the European Parliament
and of the Council on type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro
5 and Euro 6) and on access to vehicle repair and maintenance information, amending Directive 2007/46/EC of the European
Parliament and of the Council, Commission Regulation (EC) No 692/2008 and Commission Regulation (EU) No 1230/2012 and
repealing Commission Regulation (EC) No 692/2008 (OJ L 175, 7.7.2017, p. 1, ELI: http://data.europa.eu/eli/reg/2017/1151/oj).

ANNEX IV
MANIPULATION DEVICES AND MANIPULATION STRATEGIES
1. INTRODUCTION
1.1. This Annex sets out the tests, methods and procedures for establishing the absence of manipulation devices and
manipulation strategies as construed under Article 4(5) of Regulation (EU) 2024/1257 and in accordance with
manufacturers’ obligations under Article 4 of the same Regulation.
1.2. This Annex also specifies the documentation that ensures the proper monitoring and enforcement of rules related
to manipulation devices and manipulation strategies. It aims to strengthen emissions control mechanisms,
enhance transparency, and ensure that vehicles comply with regulatory requirements for the lifetime of the
vehicles, particularly Euro 7 exhaust emission and evaporative emission limits under the conditions set out in
Annex III of Regulation (EU) 2024/1257, as well as the prohibition of manipulation devices and manipulation
strategies.
1.3. Specifications for methodologies, tests and procedures that relate to data integrity, such as manipulation of data
related to sensors, fuel or electric energy consumption, electric range or battery durability, are provided for in
Implementing Regulation (EU) 2025/1707.
1.4. This Annex also sets out roles and responsibilities for the actors involved to ensure compliance with the above-
mentioned regulatory requirements and prohibition of manipulation devices and manipulation strategies.
1.5. For the purposes of this Annex, manipulation devices and manipulation strategies should be construed as set out
by Article 3(41) and 3(42) of Regulation (EU) 2024/1257. The notion of manipulation strategy shall be
distinguished from respectively the notions of ‘Base Emission Strategies (BES)’ and ‘Auxiliary Emission Strategies
(AES)’ which are defined in respectively Article 2(17) and 2(18) of this Regulation, and which relate to
documentation requirements under this Annex.
2. GENERAL REQUIREMENTS – TESTS AND METHODOLOGIES
2.1. Referring to the provisions of Articles 3(41) and 3(42) of Regulation (EU) 2024/1257, (i) manipulation devices
and manipulation strategies related to emissions (exhaust, evaporative or other); and (ii) manipulation devices and
manipulation strategies related to data integrity should be distinguished.
2.2. When assessing situations that could involve the use of manipulation devices or manipulation strategies for
exhaust and evaporative emissions, a broad assessment and interpretation of those situations should be made.
Any devices or strategies that reduce the effectiveness of exhaust and non-exhaust emission limits and testing
condition requirements under this Regulation, that cause a non-compliant vehicle to appear compliant or that
falsify test results, should be considered when determining whether manipulation devices or manipulation
strategies exist. Market surveillance authorities should apply dedicated screening tests and enforcement measures
to prevent the circumvention of Euro 7 requirements.
2.3. The assessment of such situations as part of type-approval should distinguish and identify specific situations
where the reduction of effectiveness of exhaust and evaporative emission control(1) is justified by technical
reasons and is not due to manipulation. This is particularly relevant in driving conditions that are adjacent to one
or more boundary conditions of a regulated emissions test. For such situations, manufacturers shall comply with
criteria for the declaration of technically justified emission control strategies that are only active for a specific set
of ambient or operating conditions, thereby documenting and explaining the reduction of the effectiveness of
emission control that may be observed (for instance, the dosing of reagent may stop at very low temperatures due
(1) Regulation (EU) 2024/1257, recital (26).

OJ L, 5.9.2025
to physical limitations of hardware). These technically justified emission strategies shall satisfy strict criteria to
demonstrate that they are acceptable and that therefore they do not constitute a manipulation device or
manipulation strategy as defined in Regulation (EU) 2024/1257, without prejudice to the requirements set out in
Article 4(2) of the same Regulation. The methodology for the assessment and approval of AES is specified in
Appendix 1 to this Annex.
2.4. Manufacturers shall ensure that no vehicle is equipped with manipulation devices or strategies related to data
integrity as defined in paragraphs 41 and 42 in Article 3 of Regulation (EU) 2024/1257.
2.5. Manufacturers shall not introduce software or calibration updates that manipulate data related to sensors, fuel or
electric energy consumption, electric range or battery durability, either before or after the placing in the market.
2.6. Manufacturers shall disclose any software and calibration updates affecting the integrity of data related to sensors,
fuel or electric energy consumption, electric range or battery durability to the granting type-approval authority.
3. TECHNICAL REQUIREMENTS – DOCUMENTATION
3.1. Manufacturers shall document Auxiliary Emission Strategies (AES) at type-approval. The procedure of assessing
AES ensures the consistent approval of elements of design or actions, in line with Article 14(7) of Regulation
(EU) 2024/1257. For the type-approval authorities to be able to assess the proper use of AES, considering the
prohibition of manipulation devices and manipulation strategies contained in Article 4(5) of Regulation
(EU) 2024/1257, the manufacturer shall provide an extended documentation package, as described in Appendix
1 to this Annex.
3.2. The extended documentation shall remain strictly confidential. It may be kept by the approval authority, or, at the
discretion of the approval authority, may be retained by the manufacturer. In the case the manufacturer retains the
documentation package, that package shall be identified and dated by the approval authority once reviewed and
approved. It shall be made available for inspection by the approval authority at the time of approval or at any
time during the validity of the approval.
3.3. Manufacturers shall also provide to the approval authorities a formal documentation package, as described in
Appendix 2 to this Annex, containing information on AES/BES that would allow an independent tester to
identify if the emissions measured can be attributed to an AES or BES strategy or are potentially due to a
manipulation device or manipulation strategy.
3.4. Manufacturers shall make the formal documentation package available to all type-approval authorities, technical
services, market surveillance authorities, recognised third parties and the Commission upon request.
3.5. Manufacturers shall introduce an indicator (AES flag or timer) to indicate when a vehicle runs in a mode where an
AES that has been documented in the extended documentation package is active instead of BES mode. The
indicator shall be available via the serial port of the standard diagnostic connector upon request of a generic scan-
tool. The AES that is running shall be identifiable via the formal documentation package.
4. ROLES AND RESPONSIBILITIES
4.1. This paragraph sets out roles and responsibilities for the actors involved to ensure compliance with regulatory
requirements:
— For vehicle manufacturers: it introduces criteria for the declaration of justified auxiliary emission control
strategies that are active for a specific purpose and in response to a specific set of ambient or operating
conditions. These emission control strategies shall satisfy strict technical criteria to demonstrate that they
do not constitute a manipulation device or manipulation strategy as defined in Regulation (EU) 2024/1257.
ELI: http://data.europa.eu/eli/reg_impl/2025/1706/oj 53/107EN
OJ L, 5.9.2025
— For type-approval authorities: it introduces criteria for the approval of technically justified emission control
strategies. The approval of such emission control strategies relies on the concept of ‘Auxiliary Emission
Strategies’ (AES), which is adapted from the Euro 6 legal framework. This Annex supports the
documentation of AES and clarifies their role in aiding emissions measurement and monitoring through
on-board monitoring systems (OBM).
— For market surveillance authorities: it sets a framework for the detection of manipulation devices and
manipulation strategies using dedicated screening tests and enforcement measures to prevent the
circumvention of Euro 7 requirements.
— For recognised third parties and the European Commission: it sets out roles in the performance of screening
tests.
4.2. Roles and responsibilities of vehicle manufacturers
4.2.1. Manufacturers shall ensure the absence of manipulation devices and manipulation strategies related to emissions
under the scope of this Regulation: manufacturers shall ensure that no vehicle is equipped with manipulation
devices or strategies as defined in paragraphs 41 and 42 in Article 3 of Regulation (EU) 2024/1257.
4.2.2. Manufacturers shall document software updates to vehicles in service that reduce the effectiveness of emissions
control strategies after type-approval.
4.2.3. Manufacturers shall disclose any software updates or calibrations affecting exhaust emissions control systems to
the granting type-approval authority.
4.2.4. Manufacturers shall document Auxiliary Emission Strategies (AES) as part of type-approval as specified in
paragraph 3 ‘Technical requirements – documentation’.
4.2.5. The manufacturer shall cooperate with the type-approval authority to allow them to select up to a maximum of 5
AES that will be monitored by OBM according to Annex I of Implementing Regulation (EU) 2025/1707.
4.3. Roles and responsibilities of type-approval authorities
4.3.1. At the request of the manufacturer, the approval authority shall conduct a preliminary assessment of the AES for
new vehicle types with regard to emissions, together with the selection of AES according to paragraph 4.2.5. In
that case, the relevant documentation shall be provided to the type-approval authority between 2 and 12 months
before the start of the type-approval process.
4.3.2. The type-approval authority shall make a preliminary assessment based on the extended documentation package,
as described in point (b) of Appendix 2 to this Annex, provided by the manufacturer. The approval authority shall
make the assessment in accordance with the methodology described in Appendix 1 to this Annex. The type-
approval authority may deviate from that methodology in exceptional and duly justified cases.
4.3.3. The preliminary assessment of the AES for new vehicle types with regard to emissions shall remain valid for the
purposes of type-approval for a period of 18 months. That period may be extended by the type-approval
authority by a further 12 months at the request of the manufacturer.
4.3.4. In cooperation with the manufacturer, the type-approval authority shall select up to a maximum of 5 AES that will
be monitored by OBM according to Annex I of Implementing Regulation (EU) 2025/1707. The selection of AES
shall prioritise those AES with the greatest expected impact by combination of their effect upon emissions when
they are active and their expected rate of activation while the vehicles are in use.
54/107 ELI: http://data.europa.eu/eli/reg_impl/2025/1706/ojEN
OJ L, 5.9.2025
4.3.5. The extended documentation package shall be identified and dated by the type-approval authority. If the extended
documentation package is kept by the type-approval authority, it shall be retained for at least 10 years after the
approval is granted.
4.3.6. The type-approval authority shall evaluate the documentation of software updates that reduce the effectiveness of
emissions control strategies after type-approval and extend the approval as appropriate as long as the
requirements continue to be met.
4.3.7. The type-approval authority may test the functionality of the AES flag or timer to indicate when a vehicle runs in
AES mode instead of BES mode.
4.3.8. Type-approval authorities shall ensure a harmonised assessment of Auxiliary Emission Strategies (AES). A list of
AES which were deemed non-acceptable by type-approval authorities shall be compiled yearly by the Forum for
Exchange of Information on Enforcement and made available to the public by the Commission at the latest by
end of March of the following year, in case there were AES which were deemed non-acceptable by the Forum.
4.4. Roles and responsibilities of market surveillance authorities
4.4.1. Market surveillance authorities may conduct screening tests to detect manipulation devices and manipulation
strategies related to emissions.
4.4.2. Market surveillance authorities should decide case-by-case which methods are best suited, based on an appropriate
risk assessment which considers possible non-compliance, the likelihood of its occurrence, and other possible
indicators, like the severity of the occurrence.
4.4.3. The search for manipulation devices or strategies could include two distinct cases:
Case A) ‘Boundary detection’: manipulation devices or strategies that use the regulated test boundaries or
surrogates thereof as triggers (such as ambient temperature, altitude, trip duration, fuel consumed and driving
dynamics ranges); or
Case B) ‘Test detection’: manipulation devices or strategies triggered by the presence of test equipment (e.g.
backpressure increase at the tailpipe, signals on rear ultrasonic sensors, connection of a data recorder on the OBD
port) or the vehicle localization (i.e. anything informing the vehicle that it is being tested on road for tailpipe
emissions). These ‘Test detection’ manipulation devices or manipulation strategies apply primarily to on-road
tests with PEMS, since vehicles tested in the laboratory usually need to use a special ‘chassis dynamometer mode’
to allow emissions testing without triggering safety devices, etc.
4.4.4. For all screening test campaigns, it shall be necessary, as a minimum, to include testing the vehicle with the
regulatory methodologies. This is an important step to make sure that the vehicle is free of malfunctioning, poor
maintenance or other similar issues, which would unduly increase the level of emissions.
4.4.5. To detect the presence of manipulation devices or strategies according to Case A, it is necessary that the vehicles
are tested under variations of the regulated testing conditions referred to as ‘modalities’. The set of modalities is
not fixed but instead kept open due to the need to detect specific technology behaviours in response to a complex
set of parameters and the need to keep an unpredictable character.
4.4.6. Market surveillance authorities shall enforce the prohibition of manipulation devices and manipulation strategies
related to emissions. If a manipulation device or strategy related to emissions is identified, market surveillance
authorities shall proceed in accordance with Chapter XI of Regulation (EU) 2018/858.
4.4.7. Market surveillance authorities shall ensure a uniform application of criteria for the assessment of screening tests
by having regard to the latest version of the relevant non-binding guidance published by the European
Commission and to the information available within the Forum for Exchange of Information on Enforcement.

Appendix 1
Methodology for the assessment and approval of AES and BES
This appendix provides a structured approach for assessing and approving Auxiliary Emission Strategies (AES) and Base
Emission Strategies.
1. Documentation of AES and BES
1.1. Manufacturers shall include a technical description of their BES in the extended documentation package according
to Appendix 2.
1.2. Manufacturers shall document all AES, with the possible omission of certain AES according to paragraph 1.5.
Manufacturers shall justify the use of an AES that is documented based on one or more of the following criteria:
(a) The AES is necessary for the safe operation of the vehicle.
(b) The AES is necessary to avoid sudden and irreparable damage to a powertrain(1)component.
(c) The AES is only active during engine start.
(d) The AES is necessary due to physical limitations of the emission control system.
1.3. For each AES that is documented, manufacturers shall submit:
— A description of the technical motivation for the AES. This will be substantiated by supporting evidence,
such as durability tests or risk analyses, demonstrating why the AES is technically necessary;
— A description of the precise conditions that lead to the activation and de-activation of the AES. This shall
include, as appropriate, engine parameters, ambient parameters and any other relevant condition;
— An estimation of the emissions and CO impact of the AES when it is active;
2
— An estimation of the expected rate of activation of the AES while the vehicles are in use.
1.4. The information referred to in paragraph 1.3 shall be included in the extended documentation package according
to Appendix 2.
1.5. Manufacturers may omit any AES from the extended documentation package provided they meet one or more of
the following conditions:
— The AES does not lead to the exceedance of limit values defined in Annex I of Regulation (EU) 2024/1257
while it is active;
— The AES does not reduce the effectiveness of the emission control systems while it is active;
— The conditions that lead to the activation of the AES are substantially included in the test procedures.
2. Assessment of AES and BES
2.1. Authorities shall approve a BES that satisfies the documentation requirements of paragraph 1.1.
(1) As defined in Mutual Resolution No 2 (M.R.2) of the 1958 and 1998 Agreements of UNECE.
ELI: http://data.europa.eu/eli/reg_impl/2025/1706/oj 57/107EN
OJ L, 5.9.2025
2.2. Authorities shall approve an AES that is documented if it is technically justified by one or more criteria under
paragraph 1.2, provided that the following criteria are also met:
— The technical motivation for the AES is satisfactory and supported by appropriate evidence;
— The conditions that lead to the activation and de-activation of the AES are set according to technical
characteristics of the emission control systems concerned and not to the boundary conditions or other
conditions covered by a regulatory test.
3. Approval of AES and BES
The type-approval authority shall approve the AES and BES submitted by the manufacturer based on the contents
of the extended documentation package.
The extended documentation package shall be limited to 100 pages.
The extended documentation package may be complemented with annexes and other attached documents,
containing additional and complementary elements, if necessary. The manufacturer shall send a new consolidated
version of the extended documentation package (with tracked changes) to the type-approval authority every time
changes are introduced to the AES. The new version of the AES shall be evaluated and approved by the type-
approval authority.
The extended documentation package shall include a declaration of the software versions and calibrations used to
control these AES/BES, including the appropriate checksums or reference values of these software versions and
calibrations, as well as instructions to the authority on how to read the checksums or reference values; the
declaration shall be updated and sent to the type-approval authority that holds this extended documentation
package each time there is a new software version or calibration that has an impact on the AES/BES.
Manufacturers may request to use an alternative to a checksum if it provides an equivalent level of traceability for
software version and calibration management.
The extended documentation package shall also include a declaration of the manufacturer on the absence of
manipulation devices or manipulation strategies. The approval of the extended documentation package shall not
constitute proof of the absence of manipulation devices or manipulation strategies.

ANTI-TAMPERING, SECURITY AND CYBERSECURITY
1. INTRODUCTION
This Annex lays down measures regarding the type-approval of anti-tampering, security and cybersecurity
systems.
2. DEFINITIONS
For the purposes of this Annex, the definitions in UN Regulation No 155(1)shall apply.
‘Attacks’ shall be understood as comprising tampering attempts, attempts to circumvent security and cyber-
attacks.
3. REQUIREMENTS FOR TYPE-APPROVAL
3.1. Responsibilities of manufacturers
It is the responsibility of the manufacturer that the vehicle type (with regard to emissions) is equipped with
sufficient anti-tampering, security and cybersecurity measures to make it resistant against tampering,
cybersecurity and security threats arising in all phases of its life-cycle.
To fulfil this responsibility, the vulnerabilities that may lead to tampering shall be minimised to the fullest extent
possible, based on the best available knowledge at the time of type-approval, for all systems listed in Article 4(7)
of Regulation (EU) 2024/1257.
This shall be deemed to be complied with when:
(a) the vehicle type with regard to emissions satisfies the requirements of UN Regulation No 155;
and
(b) the manufacturer’s vulnerability/threat analysis and risk assessment consider, where applicable, the aims of
Regulation (EU) 2024/1257 and in particular:
(i) for fuel and reagent injection system, engine and engine control units and pollution control systems,
the manufacturer’s vulnerability/threat analysis and risk assessment considers at least the high-level
vulnerabilities/threats, examples of vulnerabilities or attack methods, and examples of mitigations of
Table 4.1 of Appendix 1 to this Annex;
(ii) for the OBM system, OBD system and OBFCM device the manufacturer’s vulnerability/threat analysis
and risk assessment considers at least the high-level vulnerabilities/threats, examples of vulnerability
or attack method, and examples of mitigations of Table 4.2 of Appendix 1 to this Annex;
(iii) for the odometer, the total distance indicated and total distance values are protected according to UN
Regulation No 39(2)as amended by the 02 series of amendments;
(iv) for traction batteries and related management systems, electric motor and related control units and
environmental vehicle passport, the manufacturer’s vulnerability/threat analysis and risk assessment
considers at least the high-level vulnerabilities/threats, examples of vulnerabilities or attack methods,
and examples of mitigations of Table 4.3 of Appendix 1 to this Annex.
Without prejudice to requirements of paragraph 7.2.2.2(g) of UN Regulation No 155, the manufacturer shall
monitor for, detect, respond to and inform the approval authority on evidences of successful attacks on any of
the systems listed in Article 4(7) of Regulation (EU) 2024/1257.

3.2. Responsibilities of approval authorities
Without prejudice to the requirements of paragraph 5.1.1 of UN Regulation No 155, type-approval authorities
shall verify whether the vulnerability/threat analysis and risk assessment conducted by the manufacturer is
appropriate and sufficient. This verification shall ensure that the vulnerabilities and threats of the tables in
Appendix 1 have been appropriately managed by the manufacturer. The examples in these tables shall be used as
reference.
The type-approval authority may require additional documentation to verify that the proposed mitigation actions
are correctly implemented.
Type-approval authorities are encouraged to exchange best practices and experiences within the framework of the
Forum for Exchange of Information on Enforcement as established in Regulation (EU) 2018/858.
3.3. Responsibilities of market surveillance authorities
Following the requirements in Article 8 to Regulation (EU) 2018/858(3), the market surveillance authorities shall
carry out regular tests to verify whether anti-tampering, security and cybersecurity measures are sufficient. Market
surveillance authorities shall be responsible for vehicle selection, application of testing methods, follow-up
activities, reporting and corrective or restrictive measures.
3.3.1. Vehicle selection for market surveillance
When carrying out market surveillance tests, the market surveillance authorities shall select the vehicle types with
regards to emissions to be tested based on a risk assessment. Vehicle types (with regards to emissions) deemed to
pose a greater risk according to the risk assessment shall be prioritised for testing according to paragraph 3.3.2.
The risk assessment shall consider the following aspects:
(a) Evidence that effective tampering products are widely available on the market for use on certain vehicle
types with regard to emissions;
(b) Evidence of known vulnerabilities affecting certain vehicle types with regard to emissions;
(c) Evidence about the prevalence of tampering for certain vehicle types with regard to emissions (including,
among others, OBM data submitted by vehicle manufacturers);
(d) The number of vehicles in circulation belonging to certain vehicle types with regards to emissions;
(e) Other relevant information, including test results of recognised third parties and information exchanged in
the Forum for Exchange of Information on Enforcement, as established in Regulation (EU) 2018/858.
3.3.2. Testing methods
Market surveillance authorities may employ any test method to establish whether vehicles belonging to a certain
vehicle type with regard to emissions are sufficiently protected against attacks which could affect the proper
operation of systems listed in Article 4(7) of Regulation (EU) 2024/1257. Market surveillance authorities are
encouraged to exchange best practices and experiences within the framework of the Forum for Exchange of
Information on Enforcement as established in Regulation (EU) 2018/858.
The good state of each test vehicle shall be verified before conducting the tests, ensuring in particular the proper
operation of systems listed in Article 4(7) of Regulation (EU) 2024/1257 and that they have not been subject to
attacks in the scope of the tests. The verification shall ensure that no relevant fault code is stored nor any relevant
warning light is on, that none of the pollutant monitoring statuses is in ‘Error’ and that the tampering detection
level as set out in Annex I to Implementing Regulation (EU) 2025/1707 reported by the OBM is ‘Level 0’.

ELI: http://data.europa.eu/eli/reg_impl/2025/1706/oj 83/107EN
OJ L, 5.9.2025
This verification shall also include, where appropriate, the performance of an ex anteType 1 or RDE test according
to this Regulation. The attack test shall not proceed unless the emission results of the ex ante test fulfil the
applicable emission limits.
The tests conducted by market surveillance authorities shall aim to reproduce the attacks likely to be experienced
by certain vehicle types with regard to emissions in the field due to a high benefit-cost ratio. These may include
attempts to tamper with vehicles by exploiting existing tampering, security and cybersecurity vulnerabilities, or
by installing tampering products that are available on the market. The selection of attacks shall be based on the
risk assessment described in paragraph 3.3.1.
3.3.3. Test evaluation
The market surveillance authority shall determine the outcome of the test by evaluating the effects of the attack on
exhaust emissions or on the integrity of the data used by the systems listed in Article 4(7) of Regulation
(EU) 2024/1257, taking account of the response of the vehicle to the attacks. The authority shall come to a ‘pass’,
‘follow-up’ or ‘fail’ decision on one or both aspects, as appropriate according to the nature of the attack.
A ‘pass’ outcome requires no further action.
A ‘follow-up’ outcome shall be followed by the activities described in paragraph 3.3.4.
A ‘fail’ outcome shall be followed by the activities described in paragraph 3.3.5.
Following the attack, the market surveillance authority may condition the vehicle by driving it over a certain
distance, over multiple trips, or in other conditions that are deemed appropriate for the attack to be detected.
3.3.3.1. Evaluation of effects on exhaust emissions (pollutants monitored by OBM)
After the attack and optional conditioning, an ex postType 1 or RDE test shall be performed. The ex anteand ex post
tests shall be of the same type. If two RDE tests are driven, the tests shall be performed over the same route, with
similar driving behaviour, and under comparable environmental and traffic conditions.
Following the ex post emissions test, the test outcome shall be determined for each pollutant monitored by the
OBM system. The test outcome shall be considered a ‘pass’ if one of the following is observed:
(a) Exhaust emissions do not increase substantially from those of the ex ante emissions test. A substantial
increase shall be understood as an exhaust emissions increase by more than 100 % of the applicable
emission limit and where emissions of the ex posttest are above the applicable OBD threshold.
(b) Exhaust emissions are substantially increased to a level of up to 2,5 times the applicable emission limit,
while the tampering detection level is set to ‘Level 1’ or higher.
(c) Exhaust emissions are substantially increased to a level equal or higher than 2,5 times the applicable
emission limit, while the tampering detection level is set to ‘Level 2’ and the corresponding OBM status has
transitioned to ‘Error’.
If the test outcome is not a direct ‘pass’, the vehicle may be conditioned further to allow more evaluation time for
the OBM system to transition the pollutant monitoring statuses and tampering detection level.
When, after further conditioning, the monitoring statuses or tampering detection level do not transition in such a
way that they lead to a ‘pass’ outcome, the test outcome shall be considered a ‘follow-up’ if one of the following
outcomes is observed:
(a) Exhaust emissions are substantially increased to a level of up to 2,5 times the applicable emission limit,
while the tampering detection level is set to ‘Level 0’.
(b) Exhaust emissions are substantially increased to a level equal or higher than 2,5 times the applicable
emission limit, while the corresponding OBM status has transitioned to ‘Error’ and the tampering detection
level is set to ‘Level 1’ or lower.
If the outcome is neither a ‘pass’ nor a ‘follow-up’, it shall be considered a ‘fail’.
84/107 ELI: http://data.europa.eu/eli/reg_impl/2025/1706/ojEN
OJ L, 5.9.2025
Vehicles not equipped with an OBM system shall be excluded from the evaluation of the effects on exhaust
emissions according to this paragraph.
3.3.3.2. Evaluation of effects on exhaust emissions (pollutants not monitored by OBM)
After the attack and optional conditioning, an ex postType 1 or RDE test shall be performed. The ex anteand ex post
tests shall be of the same type. If two RDE tests are driven, the tests shall be performed over the same route, with
similar driving behaviour, and under comparable environmental and traffic conditions.
Following the ex postemissions test, for all pollutants not monitored by the OBM system, the test outcome shall be
considered a ‘follow-up’ when the pollutants are substantially increased to a level above the applicable OBD
threshold values as specified in paragraph 6.8.2 of UN Regulation No 154 while the malfunction indicator (MI) is
not activated. In any other case, it shall be considered a ‘pass’.
If the test outcome is not a direct ‘pass’, the vehicle may be conditioned further to allow more evaluation time for
the OBD system to activate the malfunction indicator.
3.3.3.3. Evaluation of effects on the integrity of data
Following the attack and optional conditioning, the outcome shall be considered a ‘pass’ when the attack is
unsuccessful in modifying data of the systems listed in Article 4(7) of Regulation (EU) 2024/1257.
If the attack is successful in modifying data of the systems listed in Article 4(7) of Regulation (EU) 2024/1257, the
outcome shall be evaluated by the market surveillance authority on the following two criteria:
(a) Impact: what the relevance of data modification is in terms of impact on the environment or on the aims of
Regulation (EU) 2024/1257;
(b) Response: whether the vehicle responded by adequately conveying information about the invalidity of the
modified data.
When the impact is regarded as insignificant, the outcome shall be considered a ‘pass’.
When the impact is regarded as significant, and the response is deemed adequate by the authority, the outcome
shall be considered a ‘pass’.
When the impact is regarded as significant and the response is deemed inadequate, the outcome shall be
considered a ‘follow-up’. In such cases, the market surveilance authority shall contact the manufacturer to inform
them of the outcome of the test, the characteristics of the vehicle and the nature of the tests performed.
The manufacturer may propose further conditioning to allow additional time for the vehicle to respond to the
attack, or repeated tests on similar vehicles. Following the further conditioning or repeated tests, the response of
the vehicle shall be evaluated. If the vehicle response is still deemed inadequate by the market surveillance
authority, the outcome shall be confirmed as a ‘follow-up’. If the response of the vehicle is deemed adequate, the
outcome shall be considered a ‘pass’.
3.3.4. Follow-up activities
In the case of an attack with an outcome considered as ‘follow-up’, it shall be investigated in detail, where
necessary in cooperation with the manufacturer and the granting type-approval authority, to establish:
(a) which vulnerabilities were exploited and whether these were identified at the time of type-approval;
(b) in case that vulnerabilities were identified at the time of type-approval, whether the mitigation measures
have been properly applied;
(c) whether the vulnerabilities apply to other vehicle types with regard to emissions.
ELI: http://data.europa.eu/eli/reg_impl/2025/1706/oj 85/107EN
OJ L, 5.9.2025
Without prejudice to requirements of Chapter XI of Regulation (EU) 2018/858, the manufacturer shall, within a
period agreed with the market surveillance authority, propose a technical solution to the market surveillance
authority to increase the resistance of the vehicle against attacks, either by effectively mitigating the exploitation
of the vulnerability or by implementing methods to detect the attack and initiate an appropriate response, along
with a plan to implement this technical solution. The market surveillance authority shall evaluate the technical
solution and accompanying implementation plan and request modifications where appropriate.
When the technical solution and implementation plan are accepted by the market surveillance authority, the
manufacturer shall proceed with the implementation of the technical solution as agreed with the market
surveillance authority.
When the technical solution and implementation plan fail to satisfy the market surveillance authority, the
outcome shall be considered a ‘fail’.
The results of the investigation of attacks with a ‘follow-up’ outcome shall be brought to the attention of to the
Forum for Exchange of Information on Enforcement as established in Regulation (EU) 2018/858.
3.3.5. Reporting, corrective and administrative measures following a ‘fail’ outcome
A ‘fail’ outcome upon an attack shall be investigated in detail, where necessary in cooperation with the
manufacturer and the granting type-approval authority, to establish:
(a) which vulnerabilities were exploited and whether these were identified at the time of type-approval;
(b) in case that vulnerabilities were identified at the time of type-approval, whether the mitigation measures
have been properly applied;
(c) whether the vulnerabilities apply to other vehicle types with regard to emissions.
The details of tests with a ‘fail’ outcome shall be reported to the manufacturer, and the market surveillance
authorities shall require the manufacturer to take measures in accordance with Chapter XI of Regulation
(EU) 2018/858 to ensure that the exploited vulnerability is effectively mitigated, preferably by an over-the-air
software update of the relevant vehicle systems according to UN Regulation No 156(4).
In determining the appropriateness of corrective measures, authorities shall consider the state of technology of the
vehicle type with regard to emissions, the technical feasibility of possible mitigations and the likelihood of
exploitation of the vulnerability (approximated by the benefit-cost ratio of the attack). The manufacturer may,
with appropriate supporting evidence, demonstrate that a vulnerability cannot be effectively mitigated or that an
appropriate response from the tampering detection cannot be realised, due to technical limitations of the vehicle’s
architecture. If the manufacturer comprehensively demonstrates to the market surveillance authority that a
mitigation is not technically feasible, the manufacturer shall not be required to provide corrective measures.
The results of the investigation of attacks with a ‘fail’ outcome shall be brought to the attention of to the Forum for
Exchange of Information on Enforcement as established in Regulation (EU) 2018/858. In case of vulnerabilities
that cannot be effectively mitigated due to technical limitations are identified, the Forum for Exchange of
Information on Enforcement shall consider requesting corresponding additional mitigations in future type
approvals.
3.4. Roles and responsibilities for the Commission and recognised third parties
The Commission and recognised third parties may verify whether vehicles belonging to a certain vehicle type with
regard to emissions are sufficiently protected against tampering attempts, security and cybersecurity attacks
affecting the systems listed in Article 4(7) of Regulation (EU) 2024/1257 according to the methods described in
paragraph 3.3.2.
(4) UN Regulation No 156 – Uniform provisions concerning the approval of vehicles with regards to software update and software

two parts: (a) The formal documentation package for the approval, according to documentation requirements in
UN Regulation No 155 paragraph 3.3, which shall be supplied to the type-approval authority at the time of
submission of the type approval application. This documentation package shall be used by the type-approval
authority as the basic reference for the approval process. The type-approval authority shall ensure that this
documentation package remains available for at least 10 years counted from the time when production of the
vehicle type (with regard to emissions) is definitively discontinued; (b) Additional material relevant to the
requirements of this regulation may be retained by the manufacturer, but made open for inspection at the time of
type-approval. The manufacturer shall ensure that any material made open for inspection at the time of type
approval remains available for at least a period of 10 years counted from the time when production of the vehicle
type (with regard to emissions) is definitively discontinued.
In cases where information is shown to be covered by intellectual property rights or to constitute specific know-
how of the manufacturer or of their suppliers, the manufacturer or their suppliers shall make available sufficient
information to enable the checks referred to in this Regulation to be made properly. Such information shall be
treated on a confidential basis.
