Was in the workshop and the exhaust manifold cat was replaced as well as cylinder head newly installed, all in all around the 2,800,– EUR and now the following: Immediately when driving home, when stopping at the first traffic light the engine stutters (when rolling out), the body shakes powerfully and the car almost drains when I leave the brake slightly (light still red) and the car rolls it slowly away. The whole thing then happened almost every time while braking, on the 2nd day still but long nic It happens as often as the day before, then days 3-4 only sporadically, but it still happens. Especially when I go down into the underground garage it happens every time (car tilts forward into the driveway while I open up). What can that be? It also happens when I stand at the traffic light after about 3-4 minutes, briefly stuttering, paired with powerful shaking of the body and then sometimes sink down, sometimes slightly roll up and is gone. Does anyone have any idea?
