I have a 2001 330i w/sp. Last week I put the car on a truck to the dealer after I heard metal on metal while traveling down the highway. The dealer determined it was the differential and that it needed to be replaced. I picked up the car Monday night and yesterday evening while driving home I heard the same noise again. I brought it into the dealer first thing this morning. Has anyone else had this problem. I can't imagine I am doing anything wrong in my driving that was cause two differentials to fail. I even told myself to treat it as a new car when I got it back, and not go over 100mph, to allow the new diff to break in properly. And for the record, on the service order, it noted that it was a refurbished diff they installed. Thank BMW!
