After being questioned by U.S. law firm Jones Day, insiders claim that Audi chief executive Rupert Stadler had no prior knowledge of dieselgate.

It is also reported by Reuters that an internal investigation commissioned by the Volkswagen Group itself found no evidence against Stadler either.

While the parties involved are refusing to comment, it is thought that VW’s supervisory board spoke about the findings on Friday.

Initially, it was asserted that Stadler knew that Audi was manipulating emissions testing for its 3.0-liter TDI engine after becoming company chairman in 2007 and being appointed to VW Group’s nine-member executive board in 2010.

While Stadler may be out of hot water for the time being, the company itself is still recovering and facing repercussions from the scandal. Just last week, Audi suspended Stefan Knirsch, its research and development boss. It is also reported that four engineers have been suspended while Jones Day conducts its investigations.
