In light of the diesel rescue plan, Audi and Porsche are set to subject 850,000 cars and SUVs for an engine management software update. In their statement, Audi intends to reduce overall emissions, especially in urban areas. The service also applies to the Porsche and Volkswagen models that are fitted with the same types of engines.

Notable models fitted with this engine are the A6 V6 TDI, Q7 V6 TDI, Cayenne diesel and Touareg TDI V6 to name a few. The previous-generation Audi A8 4.2 TDI was fitted with the eight-cylinder version of the company's turbodiesel. TDI V6 and TDI V8 engines that will get the update are the ones with Euro 5 or Euro 6 compliance. Audi says that this service will be free of charge to their customers, as well as to Porsche and Volkswagen customers.

Since its mother company, the Volkswagen Auto Group, has admitted to emissions tampering, Audi has cooperated closely with the authorities and reported to them, in particular the Federal Ministry of Transport and the Federal Motor Transport Authority (KBA). Audi adds that if those investigations result in further consequences, the automaker will quickly implement the required technical solutions in the interest of its customers as part of this EU5/EU6 retrofit program.

As for the diesel rescue plan, the German government will be allocating $ 2.33 billion for the program. A committee to further reduce emissions will also be established as part of the rescue plan. There will be further talks about diesel engines at an upcoming summit, to be held on August 2, 2017.
