Winterkorn stepped down days after the scandal became public in 2015, and his charges were filed secretly in March and revealed today. He's the highest-profile executive to be charged for Dieselgate thus far. Previously, Volkswagen alleged that a rogue engineer had been a mastermind of sorts uploading the software to 11 million vehicles.
But Winterkorn's indictment alleges that he knew about the emissions issue and that US regulators were threatening to hold off certifying VW's 2016 cars for sale in America, according to Bloomberg. In January, the automaker pled guilty to lying to get its cars into the US and were served a $4.3 billion fine. Five other executives have been indicted by the US but have stayed in Germany to avoid arrest. Meanwhile, almost 300,000 VW cars installed with the software slowly rot in parking lots across the US.
