Dr. Stefan Knirsch, Member of the Board of Management of Audi AG for Technical Development, has resigned, effective immediately. He had been appointed to that position at the beginning of this year, replacing Dr. Ulrich Hackenberg who left the company earlier after being suspended in connection with the diesel emissions scandal. Dr. Hackenberg has not been charged.
The company said that Dr. Knirsch had concealed knowledge about the defeat devices and the emissions testing cheating.
The Wall Street Journal reported that Knirsch became aware of Audi’s defeat device sometime after 2013, when he was put in charge of engine development at Audi, according to “a person familiar with the situation.”
