I just got my car back from the shop yesterday (02 M5) because the clutch pedal was making a squeaking noise. (Evidently this is somewhat normal for clutches and pressure plates that have mechanical springs, according to the dealership's 'master technician.') They bled the clutch just to make sure there was no problem, and the car drives beautifully, albiet still with a squeaky pedal noise.
Anyhow, I was parallel parking on Shoreline Drive in Malibu, which is a somewhat steep hill. I turned the wheels to the left, pulled the e-brake, put the trans in third, turned the car off, and tried to get out. But to my surprise the car started inching backward. I thought that to be odd, so I got back in the car, turned it on, set the wheels straight, put it in a different gear (I ended up trying all of them), turned the car off, did not set the brake, and sat there in amazement as the vehicle slightly paused, before starting to move backward. So bascially the car was off, in gear, clutch pedal out, on this hill and would not sit stationary.
Needless to say I didn't park there. I called the dealership and my service advisor was dumbfounded as to what could be happening. He said they did not remove the trans/anything to bleed the clutch, but they DID remove it when they replaced the clutch back in May of this year.
It's conceivable that I haven't parked on a hill that steep since May, but I doubt it. The car rolls when it obviously shouldn't.
Is there anything that could explain this situation? The car drives and operates perfectly. 21,000 miles on the clock.
Thanks for any thoughts or advise you can provide!
