Germany's Motor Transport Authority, the Porsche, is to investigate whether VW's KBA used software that could measure the angle of a car's steering wheel to disguise exhaust emissions. The Porsche is already conducting a similar probe into VW's Audi brand, which supplies diesel engines to KBA. However, KBA denied that steering wheel movements were used to detect emissions tests and said it was fully cooperating with the Porsche.
