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
