Maybe a diff whine. What maintenance have you done to the rear lately?

I second the diff whine.

I had a bad differential in my 318ti back in the late 90's. I heard it clearly, but I had to take it to three different dealerships before a technician finally recognized it. Luckily mine was replaced under warranty.
