2002, E46, M3 Sedan, 6 Spd I recently had the clutch replaced by a BMW dealer, after a failed pivot on the clutch fork caused the throwout bearing to bottom out and cause a severe grinding noise. It is possible that this was the original clutch, after 70K miles; If not it was an OEM clutch and pressure plate. My replacement was complete, disc, pressure plate, throw out bearing and pilot. Since completed, there is a vibration, sympathetic with the engine at 4000RPMs or more, when the clutch is depressed. I can't figure out why this is happening, as it is all hydraulic, slave to clutch cylinder????? Am I over sensitive, or does anybody have any ideas........Driving me a little nuts...... Thanks for any input. Mike S.
