Hello everybody, I bought a 645 Ci convertible a week ago. Just coming back from a Black Forest tour, almost 2000 kilometers, while the wahen swallowed itself up a little bit while accelerating, so it was extremely ruckle. A very slight jerking also occurred when cruising from time to time. On the highway the car finally reported after swallowing again “gear disturbance”, but he did not switch to emergency operation yet. After ignition was off/one the Fe Okay, I’ll have the FS read out, of course, but maybe someone can help me with some information before I get to the seller… what could that be? What do I have to reckon with? Thank you very much for your help… Greetings – Tom
