At very slow turns my car make a noise I would describe as a rubbing sound. At first that's what I thought was happening but I couldn't figure out what would be rubbing.
Then I remembered my 4 wheel drive pickup makes a terrible racket when I turn in 4 wheel at slow speeds because of the locked up differential. It tells you not to turn short right in the manual.
Does the BMW have some sort of possi traction rear end that would make that noise? Speed up slightly and there is no noise at all.
We spent 4 hrs out driving around yesterday with the top down. What a sunburn. :) I'll remember next time.
