Martin Winterkorn: Ex-VW boss comments on the diesel affair in court. Former VW boss denies responsibility for the illegal defeat devices.

He said that he only found out about the problems late and incompletely. So far, the 76-year-old had only spoken on the topic to the Bundestag investigative committee and to the law firms commissioned by VW. The scandal triggered a large number of lawsuits. Compensation for the emissions scandal, primarily fines, damages and legal fees, has so far cost Volkswagen more than 32 billion euros.
