The California Air Resources Board (CARB) apparently found a new emissions cheat device in an Audi vehicle, potentially deepening Volkswagen Group's diesel crisis.

According to a report by German newspaper Bild am Sonntag, CARB officials last summer were investigating an Audi vehicle and discovered a device in the automatic transmission. The device altered gear shifting software that reduced carbon dioxide emissions in laboratory settings. The device was activated based on steering angle--turning the wheel more than 15 degrees in either direction deactivated the cheat programing. The report claims the device was used in gasoline and diesel Audi models sold in Europe.

Reuters also reports Audi stopped using the device last May and has suspended engineers who were allegedly involved with the matter.
