Audi Emissions - Frequently Asked Questions

Here are some important FAQs relating to current developments at Volkswagen. We update this information continuously. Please note that this information is related only to the NOx-remedial action.


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

No. All the vehicles concerned are safe from a technical standpoint and roadworthy.

We have now developed solutions for 1.2, 1.6 and 2.0 litre diesel engines affected by the NOx emissions testing issue. For the 1.6 and 2.0 litre these have been approved by the relevant authorities and we expect the 1.2 to be approved very soon. In the case of the 1.2 and 2.0 litre engines the solution involves software only and it is expected that the pure labour time for this software update should take around half an hour. In respect of vehicles with 1.6 litre engines, we have developed both a software solution and a technical solution for the exchange of certain hardware components within the engine, but it is expected that this should take less than an hour.

It is our aim that the roll out of the technical solutions will commence in early 2016 but you will be contacted directly to advise when the solution is available for your particular vehicle.


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

Your car has been approved by an independent approval authority, which means it is legally allowed to be driven on the roads, and recent discussions with the relevant authorities have confirmed that this remains the case. You are not, therefore, breaking the law by driving your car. We also stress that the NOx emissions testing issue does not change the fact that your car is safe from a technical standpoint and roadworthy.


My vehicle is affected by the NOx issue. Who will contact me about the next steps?

It is our aim that the roll out of the technical solutions will commence in early 2016 but you will be contacted directly to advise when the solution is available for your particular vehicle.


My vehicle is affected by the NOx issue. Will I incur any costs in getting the repair?

No. Volkswagen will cover the costs relating directly to the repair. The aim is to minimise the inconvenience to you of implementing the technical solution.


When will I be contacted with further information?

The owners of affected vehicles will be contacted as soon as possible once the details and timings of the fix have been finalised. Our intention is for the fix to start to be implemented from early 2016.


What exactly happened during dynometer runs?

The Californian Air Resources Board CARB and the Environmental Protection Agency EPA, both of the USA, have come to the conclusion that software caused discrepancies in the values of oxides of nitrogen (NOx) during dynometer runs.


What kind of technical service measures will be taken for the NOx emissions issue?

We have now developed solutions for 1.2, 1.6 and 2.0 litre diesel engines affected by the NOx emissions testing issue. For the 1.6 and 2.0 litre these have been approved by the relevant authorities and we expect the 1.2 to be approved very soon. In the case of the 1.2 and 2.0 litre engines the solution involves software only and it is expected that the pure labour time for this software update should take around half an hour. In respect of vehicles with 1.6 litre engines, we have developed both a software solution and a technical solution for the exchange of certain hardware components within the engine, but it is expected that this should take less than an hour.

It is our aim that the roll out of the technical solutions will commence in early 2016 but you will be contacted directly to advise when the solution is available for your particular vehicle.


Are EU6 Diesel engines affected by the NOx emissions testing issue?

No, our EU6 diesel engines are not affected by the NOx emissions testing issue.


Going forward, how will people who purchase used cars be able to identify whether remedial measures have already been carried out on the vehicle? Are such vehicles identified in any way?

The method of confirmation that the solution has been implemented is being explored and yet to be confirmed in the UK. Audi's objective is to provide:

- Inclusion of a physical identifier (sticker, stamp or otherwise) in the vehicle or vehicle service record.

- Update to the electronic vehicle history (where applicable) accessible to every Authorised Repairer.

- Update to the self-service (VIN check) on the Audi website.


Can the optimised software cause any damage to the vehicle?

No, the optimised software cannot cause any damage to your vehicle. The software allowed the vehicle to recognise a test situation; the software was inactive during normal operation.


Will the planned Service action apply to all vehicles affected?

Yes, however, the measures to be carried out may differ depending on your vehicle model and engine. In the case of the 1.2 and 2.0 litre engines the solution involves software only and it is expected that the pure labour time for this software update should be around half an hour. In respect of vehicles with 1.6 litre engines, we have developed both a software solution and a technical solution for the exchange of certain hardware components within the engine, but it is expected that this should take less than an hour.


When will my car be fixed?

It is our aim that the roll out of the technical solutions will commence in early 2016 but you will be contacted directly to advise when the solution is available for your particular vehicle.
