London (CNN Business)German prosecutors have charged former Audi CEO Rupert Stadler with fraud in connection with the 2015 diesel emissions scandal that rocked the Volkswagen Group.
Volkswagen (VLKAF) has admitted that it rigged millions of diesel engines to cheat on emissions tests. Software applications, known as “defeat devices,” were installed so that engines produced fewer toxic emissions in a test environment than in normal driving conditions. Prosecutors said Wednesday that Stadler knew about the manipulation of diesel engine emissions but failed to prevent hundreds of thousands of cars with rigged software from being sold.The charges relate to nearly 435,000 Audis, Porsche and Volkswagen cars destined for the US and European markets.

This clarification is a prerequisite for the successful new start.” “The presumption of innocence continues to apply to all defendants until the allegations have been clarified,” the statement said. Stadler had worked for Volkswagen since 1990 before he was arrested in June 2018 in connection with the diesel scandal.
