Volkswagen has said time and time again they didn't know about the emission cheating until sometime in 2015. But a new report calls this into question.
German newspaper Bild am Sonntag (via Reuters) reported over the weekend that an employee known internally as "Winterkorn's fireman" notified senior managers - including Volkswagen's CEO at the time Martin Winterkorn - about the U.S. possibly probing some of VW's diesel vehicles for high emission levels back in May of 2014. The letter came from Volkswagen's product quality and safety department.
"It can be assumed that the authorities will investigate VW systems to establish whether Volkswagen has implemented test-recognition software," the letter states.
The letter was uncovered by Jones Day, the law firm conducting the Volkswagen's internal investigation.
Two sources tell Reuters that they knew about the letter, but couldn't say if Winterkorn saw the letter or not.
A Volkswagen spokesman declined to comment.
