Software irregularities discovered in Audi V6 diesel engine  

More Audi diesel vehicles are allegedly fitted with an illegal defeat device.  

Audi has paused the deliveries of certain previous-generation A6 and A7 models in Europe. The affected models of both cars are fitted with the 268bhp variant of the company’s 3.0-litre V6 diesel engine.

Audi, through its own internal investigations, found that this specific engine has irregularities in the unit’s management software. The company has now reported the issue to the Kraftfahrt-Bundesamt (KBA), Germany’s Federal Motor Transport Authority, as well as the Luxembourg vehicle registration authority.

KBA has requested a formal investigation of Audi regarding the possible presence of a previously unknown defeat device on vehicles powered by the aforementioned V6 diesel engine.

This issue was first reported by German magazine Der Spiegel, according to which roughly 30,000 units in Germany are affected. Additionally, this engine powers roughly 60,000 A6s and A7s around the world. However, Audi claims that no vehicles have been affected in North America.

Prosecutors in Munich, who have raided Audi's headquarters in the past and are already investigating 18 of its employees in connection with its parent group’s Dieselgate scandal, will reportedly soon start investigating this issue as well.
