Diesel Engine Information

Volkswagen Group and Audi are committed to an action plan action plan in respect of the NOx emissions characteristics of certain EA189 diesel engines. We now have technical measures approved in principle with the relevant type approval authority, and we will be writing to our customers in turn as we roll out the service action programme.

Customers with vehicles that are affected by the NOx issue will be kept informed over the coming weeks and months of the process to notify them when the technical measures for their vehicle is ready for implementation.

According to CARB and the EPA, fault has been found on the cars they tested with discrepancies in the values of oxides of nitrogen (NOx).

Trust Building Measure

What is Audi’s Trust Building Measure?

With the Trust Building Measure, Audi is informing its customers that it would consider any complaints that are established to have arisen as a result of the implementation of the technical measure on vehicles with EA189 type diesel engines and that relate to certain parts of the engine and exhaust treatment system. The Trust Building Measure applies for a period of 24 months from when the vehicle receives the technical measure and only to vehicles with mileage of under 160,000 miles at the time the Trust Building Measure is implemented (whichever comes earlier).

Audi has always said that implementing the technical measure has no adverse impact on fuel consumption figures, CO2 emissions figures, engine output, torque, noise emissions, or durability of the engine and its components. All figures relevant to type approval for the vehicle will remain valid. The regulatory authorities have expressly confirmed that the regulatory requirements are met. The confirmation also applies to the durability requirements for emission control systems. The Trust Building Measures has no bearing on this position.

With the Trust Building Measure, Audi is sending a clear signal that the update has no negative effects on vehicle durability. This measure should serve to strengthen customer confidence in the technical measure and should encourage more customers to have their cars updated.

Customers can soon receive detailed information about the terms and scope of the Trust Building Measure from all authorized dealers and workshops for their respective vehicle brand.

Which brands are offering the Trust Building Measure and which models are affected?

The Trust Building Measure applies to all Volkswagen, Volkswagen Commercial Vehicles, Audi, SEAT and ŠKODA models with EA189 type diesel engines that have received the technical measure.

To whom does the Trust Building Measure apply?

The Trust Building Measure will be offered to all Audi customers whose vehicles are fitted with an EA189 type diesel engine and who are having their vehicle updated as part of service measure 23Q7 in the context of the diesel matter. It applies only to vehicles with mileage of under 160,000 miles at the time the Trust Building Measure is implemented. To be eligible, customers must present proof that all manufacturer-recommended service and maintenance work has been completed (i.e. this applies to vehicles with a full service history).

The Trust Building Measure also extends to all customers whose eligible vehicles have already received the technical measure, from the date they received it (provided that all other requirements for the Trust Building Measure are met). The Trust Building Measure is linked to the vehicle identification number and would extend to a new owner if the vehicle is sold within the 24-month period covered by the application criteria.

The Trust Building Measure applies worldwide with the exception of the United States, Canada and South Korea, which are subject to different regulations.

Which components are covered by the Trust Building Measure?

The Trust Building Measure covers a total of 11 components within the exhaust gas recirculation system, the fuel injection system and the emissions after treatment system: lambda probe, temperature sensor, EGR changeover valve, exhaust gas recirculation valve, exhaust gas recirculation pressure differential sensor, injector, high pressure pump, fuel rail, pressure control valve, pressure sensor, high pressure pipelines.

The Trust Building Measure has no bearing on Audi’s position that the technical measures do not have any negative effects on the durability of the engine and its components. The regulators have confirmed that the technical measures meet all legal requirements and have no adverse impact on fuel consumption figures, CO2 emissions figures, engine output, torque and noise emissions.

FAQs

My vehicle is affected by the NOx issue. Can I still drive it?

Yes. The emissions issue relates to the characteristics of nitrogen oxides (NOx) emissions when experiencing test conditions.

The NOx emissions issue does not change the fact that your car remains safe and roadworthy. There is no evidence to suggest that the affected EA189 diesel engine vehicles present a risk to health or safety as a result of the NOx emissions issue.

In addition the result of your car’s MOT will not be affected by the NOx emissions issue, whether your car receives the technical measures or not and there is no reason why your car insurance would be affected by this NOx emissions issue.

My vehicle is affected by the NOx issue. Do I need to take it to a workshop immediately?

No. Once the technical measures for your vehicle are ready to be implemented, we will write directly to you with details of how and when they can be implemented in your vehicle.

Check your car

How to check if your Audi is affected?

We have developed a simple ‘self-service’ website, so you can check if your vehicle has been affected by the NOx emissions issue.

All you need to do is enter the VIN (Vehicle Identification Number) details of your vehicle. If your vehicle is unaffected, or was affected and has had the service action applied, it will show as unaffected on the website.

Please note that it can take up to 28 days from your vehicle having the technical measure applied for the website to show the service action as completed.

How to find your Vehicle Identification Number (VIN)?

You can find your VIN:

  • In the front of your service book
  • In the bottom left hand corner (passenger side) of the windscreen
  • In your MMI system under “Car” settings

Please prove that you are not a robot:

Your vehicle’s VIN is…

1M8GDM9A_KP042788

Please copy this number before proceeding to the next step.

Vehicle not found

Please check your vehicle registration number is correct and try again.

Please note that if your vehicle has been exported from the UK in the last 12 months, you should not use this VIN checker. Instead, you must use the VIN checker for the market in which your vehicle is currently registered in order to check the status of the EA 189 service action for your vehicle.

 

What happens next?

Step by step we will contact affected customers directly. We will contact you, you do not need to take any action yourself now.

Please note – we can only give information about Audi vehicles supplied in the UK. For other Volkswagen Group brands, visit the relevant brand websites for the same VIN check.
