I believe it will work on your car. You need to check to see if the part# is compatible with your car.
Go to Real oem: www.realoem.com/bmw/select.do
and enter the part #'s on the part Application search so see which one(s) are compatible with your car.
The part #'s I have available are available on this thread: http://www.e90post.com/forums/showthread.php?t=787069
