BMWZ4MC said:Sounds like it. It's a consumable part I'm afraid. Mine made a grinding sound when it failed and the window jammed. I think you can fix it yourself but it's a bit fiddly and will necessitate buying a new regulator.
Fortunately mine was at a BMW dealer at the time it died. I pointed out the grubby hand print the mechanic had left when he had lent on the top of the window whilst climbing out of the car and they fixed it for free (even though the part was visibly corroded). I now use an indy and have had no more mechanic-related injuries to my car!
You are one lucky man. Looks like this is going to cost me 390 euro to get fixed
