• 3.2.The first 3 paragraphs of section 5 shall read as follows:

‘5.   ISC TESTING

The manufacturer shall perform ISC testing for tailpipe emissions comprising at least the Type 1 test for all ISC families. The manufacturer may also perform RDE, ATCT, Type 4 and Type 6 tests for all or part of the ISC families. The manufacturer shall report to the granting type-approval authority all results of the ISC testing using the Electronic Platform for in-service conformity described in point 5.9, or other appropriate means where this is not possible.

The granting type-approval authority shall check an appropriate number of ISC families each year, as set out in point 5.4. The manufacturer shall include all results of the ISC testing in the Electronic Platform for in-service conformity described in point 5.9.

Recognised third parties may perform checks on any number of ISC families each year. They shall report to the granting type-approval authority all results of the ISC testing using the Electronic Platform for in-service conformity described in point 5.9, or other appropriate means where this is not possible.’

• 3.3.The first paragraph of section 5.7.1 shall read as follows:

‘5.7.1.   General requirements

The vehicle shall belong to an ISC family as described in point 3 and shall comply with the checks set out in the table in Appendix 1. It shall be registered in the Union and have been driven in the Union for at least 90 % of its driving time. The emissions testing may be done in a different geographical region from that where the vehicles have been selected. In case of ISC testing conducted by the manufacturer, with the agreement of the granting type-approval authority, vehicles registered in a non-EU country or vehicles which have been registered in the EU but are temporarily de-registered may be tested, if they belong to the same ISC family and are accompanied by a certificate of conformity.’

• 3.4.The final paragraph of section 5.7.1 shall read as follows:

‘A vehicle shall be excluded from ISC testing if the fuel from the vehicle tank does not meet the applicable standards laid down in Directive 98/70/EC of the European Parliament and of the Council ([^E0032]) or if there is evidence or record of fuelling with the wrong type of fuel.

• 3.5.Section 5.8 shall read as follows:

‘5.8.   Sample size

When manufacturers apply the statistical procedure set out in point 5.10 for the Type 1 test, the number of sample lots shall be set on the basis of the annual sales volume of an in-service family in the Union, as described in the following table:

Table 1

Number of sample lots for ISC testing with Type 1 tests

Registrations in the EU per calendar year of vehicles in the sampling period	Number of sample lots (for Type 1 tests)
up to 100 000	1
100 001 to 200 000	2
above 200 000	3

Each sample lot shall include enough vehicle types (with regard to emissions), in order to ensure that at least 20 % of the total registrations of this PEMS family in the EU for the previous year are covered. In case the same PEMS family is shared between more brands, then all brands shall be tested. When a family requires more than one sample lot to be tested, the vehicles selected in the second and third sample lots shall have been used in different ambient and/or typical use conditions from those selected for the first sample.’

• 3.6.Section 5.9 above Table A4/2 shall read as follows:

‘5.9.   Use of the Electronic Platform for in-service conformity and access to data required for testing

The Commission has set up an electronic platform in order to facilitate the exchange of data between on the one side, the manufacturers, other actors and on the other side the granting type-approval authority and the taking of the decision on the sample fail or pass.

The manufacturer shall complete the package on Testing Transparency referred to in Article 6 (8) in the format specified in Tables 1 and 2 of Appendix 5 and in Table 2 in this point and transmit it to the type- approval authority which grants the emission type-approval. Table 2 of Appendix 5 shall be used in order to allow the selection of vehicles from the same family for testing and along with Table 1 of Appendix 5 provide sufficient information for vehicles to be tested.

The type-approval authority which grants the emission type- approval shall upload the information in Tables 1 and 2 of Appendix 5 to the electronic platform referred to in the first paragraph within 5 working days of receiving it.’

• 3.7.In paragraph 5.10.1 after the third sub-paragraph the following new sub-paragraph shall be added to read:

‘For vehicles that have Declared Maximum RDE Values reported in point 48.2 of the Certificate of Conformity, which is lower than the emission limits set out in Table 1 of Annex I to Regulation (EU) 2024/1257, the conformity shall be checked against these Declared Maximum RDE Values. If the sample is found not to conform with the Declared Maximum RDE Values, the granting type-approval authority shall require the manufacturer to take corrective actions.’

• 3.8.In paragraph 5.10.1 a new final sub-paragraph shall be added to read:

‘The functions described above shall be executed directly in the Electronic Platform once the relevant functions are available.’

• 3.9.Section 5.10.2. shall read as follows:

‘5.10.2.   Pooling of ISC results

Test results from other actors may be pooled for the purposes of a common statistical procedure. 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 type-approval authorities, and to the electronic platform, prior to the start of testing. One of the parties shall be designated as leader of the pool and be responsible for data reporting and communication with the granting type-approval authority.’

• 3.10.The first paragraph of Section 5.10.3. shall read as follows:

‘5.10.3.   Pass/Fail/Invalid outcome for a single test

An ISC emissions test shall be considered as “passed” for one or more pollutants when the emissions result is equal or below the emission limit set out in Table 1 of Annex I to Regulation (EU) 2024/1257 for that type of test. When testing vehicles in the additional lifetime, the durability multipliers for adjusting the emission limits under Annex I to Regulation (EU) 2024/1257 shall be used.’

• 3.11.The following section 5.10.6. shall be added:

‘5.10.6.ISC for completed vehicles and multistage special purpose vehicles

The manufacturer of the base vehicle shall determine the allowed values for the parameters listed in Table 3. The allowed Parameter Values for each family shall be recorded in the information document of the emissions type-approval (see Appendix 3 to Annex I) and in the Transparency list 1 of Appendix 5. The final-stage manufacturer shall only be allowed to use the base vehicle emission values if the completed vehicle remains within the allowed Parameter Values. The parameter values for each final vehicle shall be recorded in its Certificate of Conformity.

• If the result of the test on a completed or multistage special purpose vehicle exceeds the applicable emission limits but is not higher than 1,3 times the applicable emission limits, the tester shall examine whether that vehicle complies with the values in Table 3. Any non- compliance with these values shall be reported to the granting type-approval authority. If the vehicle does not comply with those values, the granting type-approval authority shall investigate the reasons for the non-compliance and take the appropriate measures regarding the manufacturer of the completed or multistage special purpose vehicle to restore conformity, including the withdrawal of the type-approval. If the vehicle complies with the values in Table 3, it shall be considered as a flagged vehicle for the in-service conformity family for the purposes of point 6.1.

• If the result of the test exceeds 1,3 times the applicable emission limits, shall be considered as a fail for the in-service conformity family for the purposes of point 6.1., but not as an outlier for the relevant ISC family. If the completed or multistage special purpose vehicle does not comply with the values in Table 3, this shall be reported to the granting type-approval authority, who shall investigate the reasons for the non-compliance and take the appropriate measures regarding the manufacturer of the completed or multistage special purpose vehicle to restore conformity, including the withdrawal of the type-approval.’

• 3.12.Section 6.1shall read as follows:

‘6.1.Within 10 working days of the end of the ISC testing for the sample as referred to in point 5.10.5, the granting type-approval authority shall start detailed investigations with the manufacturer in order to decide whether the ISC family (or part of it) complies with the ISC rules and whether it requires remedial measures. For multistage or special purpose vehicles the granting type-approval authority shall also perform detailed investigations when there are at least three faulty vehicles with the same fault or five flagged vehicles in the same ISC family, as set out in point 5.10.6.’

• 3.13.Section 7.6. shall read as follows:

‘7.6.If the granting type-approval authority does not approve the second plan submitted by the manufacturer, it shall take all appropriate measures, in accordance with Article 53 of Regulation (EU) 2018/858, to restore conformity, including withdrawal of type-approval where necessary.’

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 ([^E0037]) 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 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.

• — 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.

• 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.

• 4.5.Roles and responsibilities of the Commission and recognised third parties

• 4.5.1.The Commission and recognised third parties may conduct screening tests to detect manipulation devices and manipulation strategies related to emissions according to paragraph 4.4.1.

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 ([^E0038]) 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 CO2 impact of the AES when it is active;

• — 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.

• 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.
