Germany's Motor Transport Authority, the KBA, is to investigate whether VW's Porsche used software that could measure the angle of a car's steering wheel to disguise exhaust emissions. The German government has been investigating emissions from Volkswagen since last year, and said on Friday it would not wait for VW to complete its own investigation. However, Porsche denied that steering wheel movements were used to detect emissions tests and said it was fully cooperating with the KBA.

The KBA is already conducting a similar probe into VW's Audi brand, which supplies diesel engines to Porsche. However, Porsche denied that steering wheel movements were used to detect emissions tests and said it was fully cooperating with the KBA.
