On the dynamometer, a so-called warm-up jumps to strategy will not be activated in real traffic. This is according to our assessment, a so-called test detection, and we consider this as an illegal defeat device."

Therefore, we will Express more a prohibition of Approval, to other Software is available, which must be approved by the force travel Federal office."
