Volkswagen executive Winfried Vahland has quit the firm rather than take charge of the diesel-testing scandal in the United States. Vahland had been named as the man who would clean up the mess but today (Wednesday, October 14, 2015) he resigned instead. News of Vahland’s bolt for the door came as media reported that at least 30 Volkswagen managers were involved in the test cheating, citing internal and external investigations. VW said the figure was without any basis.
