Hi guys I had a brand new clutch, flywheel and release bearing fitted to 2007 1.9 TDI Sportback. The car feels ten times better than before but its seemed to have created another problem. Sometimes when I start the car the gearbox jumps and the whole car shakes, the noise that it makes is as if the flywheel is stuck or something. The closest thing I can describe it to is that felling the car makes when its about to stall because you haven't pressed the clutch or put the gear into neutral when coming to a stop. Its come to a point where I don't want to drive the car anymore because its sounds like I'm damaging something every time I start it. My mechanic checked everything agin but didn't see anything unusual, but he said it could be one of the mountings but would a worn mounting cause this problem. Do any of you guys know what the issue may be or how to solve it, any input or suggestions would be greatfull.
