Hello Smart-Gemeinde I drive an F2, JG 01, petrol with 52tkm. Until now always complaintless and without the smallest problem. I carry out the maintenance myself. Now, however, I have the problem since approx. 3tkm, that when the engine is hot, the clutch rubs and pulls very strongly when starting up. The warmer the car, the worse it gets. Very bad it is then to drive on a mountain. Since almost shakes you out of the seat. In cold condition everything is like new. No rubbing and even nix. Now my question: -What is the problem? Is it known? Does ev. help a new learning of the coupling? Is ev. the surface already worn out? What about the crankshaftsimmer? Thanks for your help and greeting Wolfgang
