FAQs – updated 8 September 2017

Only certain Audi vehicles fitted with a 1.6 litre or 2.0 litre EA189 diesel engine manufactured from 2008 onwards are affected. Petrol engines are not affected.

To check if your vehicle is affected, please have your VIN number ready, and contact the Audi Information Line on 1800 50 AUDI (2834) which is open 7 days/week, 24 hours/day. See below for how to locate your VIN number.

The VIN for your car can be located in several different ways.

The easiest method would be to check the data label located on the inside cover of your Audi Service Schedule booklet (included with the vehicle log books). Alternatively, if you own an A1, A4, A5, A6, Q3 or Q5, the VIN can be found using the MMI infotainment system, navigating through the ‘Car’ menu.

You can also refer to the Owner’s Manual for the physical location of the VIN stamp. Find this information under the ‘V’ index.
The technical measures involve an update to the software in both the 1.6L and 2.0L variants of the EA189 diesel engine. In a small percentage of vehicles, a minor hardware update will also be installed.

The time needed for the implementation of the technical measures is expected to be less than one hour.


The diesel engines in question were originally developed some years ago. Since that time there have been significant advances in diesel engine technology. The update takes into account the latest findings in the development of the diesel combustion process and includes an updated fuel injection pattern, injection characteristics and rail pressure. The update is intended to ensure that vehicles operate in a single mode when the vehicles are driven in a manner that accords with the prescribed emissions testing framework.

The relevant type approval authorities for Audi vehicles conducted a review and have certified that following the implementation of the technical measures the fuel consumption figures and CO2 emissions originally listed by the manufacturer were confirmed. They have further certified that previous engine performance, maximum torque and previous noise emissions remain unchanged.

Australian Government authorities have accepted that vehicles which have had the technical measures applied meet Australian Design Rule (ADR) requirements for emissions. Australian design rules prescribe maximum emissions figures for compliance purposes which are derived from a standard dynamometer (dyno) test conducted under controlled laboratory conditions. Outside the standard dynamometer test, factors like the age of vehicle, driving style, road and traffic conditions, environmental influences, the modification of vehicles and vehicle condition can lead to figures which may differ from those calculated for new vehicles under laboratory conditions.

We are confident in the effectiveness of the software update, based on the experience of over 5,700,000 customers worldwide across the various brands who have had the update implemented to date; testing performed by type approval authorities in Europe; and the results of independent before and after testing of emissions and fuel consumption by three of the world's oldest and respected independent motorists' organisations in Germany, Switzerland and Austria and one of Germany's most widely read car enthusiasts' magazines, Autozeitung.

Audi is committed to ensuring you are completely satisfied with the update and that you continue to derive pleasure and satisfaction from driving your car. If you have any questions before or after the update is performed please contact us. You may be assured that, in the unlikely event that you do experience a negative effect on the performance of your vehicle following the update, we will be pleased to investigate and resolve any such concerns with you.

Yes, your vehicle remains safe to drive.


The software update and, where necessary in a small percentage of vehicles, the installation of a minor hardware component will be provided free of charge and be installed in less than an hour.


Emission regulations and vehicle standards vary from country to country. Regulations governing nitrogen oxide (NOx) emissions limits for vehicles in the United States are much stricter than those in other parts of the world, including Australia, and their diesel engine variants also differ significantly.

In Australia, we are conducting a voluntary recall to update your vehicle’s engine management software and where necessary, install a minor hardware component.


The ACCC has instituted proceedings against Audi, alleging Audi engaged in false, misleading or deceptive conduct in relation to diesel vehicle emission claims.

Audi is defending the claims made by the ACCC and does not think that the court action will provide any practical benefits to consumers as the approved technical measures for all cars affected by the voluntary recall are already available.

Audi Australia believes that the best outcome for those valued customers with an affected vehicle is to have the voluntary recall service updates installed.

The technical update takes less than an hour and is free of charge to customers.



Audi will not be buying back any cars in Australia. The regulations governing nitrogen oxide (NOx) emission limits are much stricter for vehicles in the USA than in other parts of the world and the engine variants are also very different. As a result, diesel engine technology has to meet much more stringent overall requirements in the USA, which also means that the technical updates for the affected vehicles are more complex. The technical updates have not yet been approved in the USA.

In addition, we hold the view that there is no legal basis for compensation or customer actions in this connection in other parts of the world. All vehicles affected are technically safe. They can be driven on roads without any limitations and can still be sold.

Implementation of the necessary technical measures is being carried out in accordance with the timetable and action plan coordinated with the German Federal Motor Transport Authority (KBA). At the same time, we currently anticipate that the affected vehicles’ modification will have no negative impact on residual value.

Minor price fluctuations are totally normal for used cars, regardless of vehicle type. What we are observing at present in the market for used diesel vehicles is, dependent on life cycle and general market trends, within the normal range of fluctuation. We are working on the assumption that the modification of the vehicles affected will not affect the residual value.

Audi believes that the best outcome for customers is the implementation of the technical measures, and strongly recommends that the technical measures for the voluntary recall are applied to customers' vehicles. All affected customers should have received a letter notifying them that technical measures are available for their vehicle and asking them to arrange an appointment with their workshop. In the meantime, your vehicle remains safe to drive.
