Audi is going to fix the problems with its 3.0-litre six-cylinder diesel engine.

The German producer is going to update the emissions control software on more than 85,000 VW Group cars that received the aforementioned TDI unit. The update will be called up for American government emission certification for the software. The automaker made a statement concerning the installation of the updated software. It is supposed to be installed after the authorities approve it.

The problem with the six-cylinder mill bears on the use of auxiliary emissions control software. It was not detected during the tests. The producer assures that the AECDs will be fully described and registered in the application together with the updated software.

Totally, 3 AECDs were used while being not declared. One of them has to deal with the temperature scenario of the exhaust-gas cleaning set-up.
