Hello, was straight in Marl and had my car miss the phase 1. The test bench measurement and everything went absolutely normal. On the return drive however, he started at speeds from 3500 to Ruckeln. In the 5th gear worse than in the 3rd all this went then once with the acceleration and strong Ruckeln also the MKL. After I took off the Astra times and then started again however this was again and also did not go on… this was rather because then I did not What can it be and how can I get it away? “feeling” somehow like ignition oscillations… Before the phase there was nothing at all… EDS I just wrote an e-mail….
