Anyone have a used diff from a 06 330i auto?? lol
Call Diffsonline.com they rebuild and replace BMW Diffs for race teams. I called them later last month cause I thought I had a bad Diff as well. Turned out that it was a bad driver side rear wheel bearing. They had a rebuilt diff for a E90 330i for about 675.
