Hello all. I have a E46 M3 with an SMG transmission. I recently replaced the clutch along with several other parts. Parts include rear main seal, DM flywheel, pressure plate, clutch disc, shift fork, throwout bearing, pivot pin (brass), slave cylinder, and compression springs. I bled the actuator/clutch using INPA and did clutch adaptation. Everything was fine until today when it started making a loud buzzing sound coming from the shift actuator area whenever I shift from N to 1 or N to R and back. If I try to drive with it like that, the car throws itself into neutral. Has anyone experienced this before? Any ideas? It does it with the key on without the engine running too.
