Hello, I am a Mechanic that is new to the BMW type flywheel. I just got a 325XI with a 5spd. The night I test drove the vehicle there was no issues and the car performed and drove great. 2 days later when it was delivered to me I went to drive it and the Clutch when depressed even slightly feels as though it has a resistant vibration. When depressed all the way that feel disappears. However, when releasing the clutch to take off the car jerks and lurches forward almost as if I have a severe case of clutch chatter. I believe what happened is the old owner did the taboo of AWD and tried to dump the clutch. I believe that the flywheel was damaged in this evolution. (not sure though) Any help would be appreciated.
