Current Customer Information

Dear Sir/Madam,

You have no doubt already heard or read about the current discussion surrounding emissions from diesel engines in the media. The nitrogen oxide (NOx) levels determined during testing were called into question.

Some vehicles have been equipped with software that optimises the nitrogen oxide values during test bench operation. We are going to update this quickly and conveniently for our customers, including specific adaptation. For this purpose, we are providing technical measures which aim to meet the pollutant emission limits without influencing either performance, engine power or consumption.

You can rely on us doing all we can to make the process as straightforward as possible for the affected customers.

The solution

2.0 TDI (EA 189): Adaptation of the software

We have developed a software solution for the 2.0 TDI engine type EA 189. An Audi Service employee will update the vehicle software using a diagnosis computer. The software optimisation will improve engine control to ensure the emission limits are met. The adaptation to the vehicle will take approximately half an hour.

 

1.6 TDI (EA 189): Adaptation of hard- and software

For the 1.6 litre engine of the type EA 189 a flow transformer will be used in addition to a software solution. Its grid stabilises the flow upstream of the mass air flow meter, thus making a more precise measuring result possible. This way, the quantity of fuel injected is more precise and the combustion process optimised. This solution is being combined with a matching software optimisation and enhanced engine control to ensure the emission limits are met. The adaptation to the vehicle will take approximately 45 minutes.

The implementation: Free of charge and straightforward


All vehicles affected will be recalled to dealerships successively to have the necessary technical solution implemented. We will contact the owners once scheduling for their vehicle has been finalised.

 


Further information


Please check whether your vehicle is affected.


You can check here whether your Audi is affected by the recall campaign for diesel exhaust gas EA189 (23Q4) by entering the vehicle's 17-character chassis number (e.g. WAUZZZ4F7AN000420). If you have any further questions, please feel free to use the contact form or to contact customer support directly.

The specified fuel consumption and emission data have been determind according to the measurement procedures prescribed by law. Since 1st September 2017, certain new vehicles are already being type-approved according to the Worldwide Harmonized Light Vehicles Test Procedure (WLTP), a more realistic test procedure for measuring fuel consumption and CO2 emissions. Starting on September 1st 2018, the New European Driving Cycle (NEDC) will be replaced by the WLTP in stages. Owing to the more realistic test conditions, the fuel consumption and CO2 emissions measured according to the WLTP will, in many cases, be higher than those measured according to the NEDC. Therefore, the usage of CO2 emission values measured according to WLTP for vehicle taxation from 1st September 2018 on can cause changes in this regard as well. For further information on the differences between the WLTP and NEDC, please visit www.audi.de/wltp.




We are currently still required by law to state the NEDC figures. In the case of new vehicles which have been type-approved according to the WLTP, the NEDC figures are derived from the WLTP data. It is possible to specify the WLTP figures voluntarily in addition until such times as this is required by law. In cases where the NEDC figures are specified as value ranges, these do not refer to a particular individual vehicle and do not constitute part of the sales offering. They are intended exclusively as a means of comparison between different vehicle types. Additional equipment and accessories (e.g. add-on parts, different tyre formats, etc.) may change the relevant vehicle parameters, such as weight, rolling resistance and aerodynamics, and, in conjunction with weather and traffic conditions and individual driving style, may affect fuel consumption, electrical power consumption, CO2 emissions and the performance figures for the vehicle. Further information on official fuel consumption figures and the official specific CO₂ emissions of new passenger cars can be found in the guide “Information on the fuel consumption, CO₂ emissions and electricity consumption of new cars”, which is available free of charge at all sales dealerships and from DAT Deutsche Automobil Treuhand GmbH, Hellmuth-Hirth-Strasse 1, 73760 Ostfildern-Scharnhausen, Germany (www.dat.de).
