BERLIN – Prosecutors in Germany said Friday they are expanding their probe into Volkswagen’s scandal over diesel cars that cheated on emissions tests, increasing the number of suspects and saying they have evidence former Volkswagen CEO Martin Winterkorn may have known of the cheating earlier than he has claimed.
The 69-year-old stepped down in September 2015, days after news emerged in the U.S. of Volkswagen’s use of software that turned off emissions controls. He said at the time that he was not aware of any wrongdoing on his part.
He said before a parliamentary committee last week that he first heard the term “defeat device,” the technical name for the illegal software, in September 2015 – even though U.S. authorities had been pressing Volkswagen for months over emissions test discrepancies and the cheating had been going for several years.
Prosecutors in Braunschweig said however that “on the basis of local prosecutorial investigation,” Winterkorn “could have known of the manipulative software earlier than publicly asserted by him.”
In a statement, prosecutors said that they have increased the number of suspects in their investigation of VW from 21 to 37 persons. It said that 28 locations including offices and private homes had been searched in Germany this week.
Winterkorn and others are now being investigated on allegations they committed fraud. In a June statement, prosecutors said Winterkorn was being investigated only for market manipulation for not making a timely disclosure of the possible financial consequences of the problem.
U.S. prosecutors have separately charged seven former Volkswagen employees. The company has agreed to pay $4.3 billion in fines to settle criminal charges and reached a $15 billion civil settlement in the U.S. with environmental authorities and car owners.
The software enabled the car to detect when it was on the test stand and turn on emission controls, and then to turn them off during normal driving.
