Has anyone else had a situation with a 325xi that shudders at 70+mph? Dealer can't seem to find this problem. Car has to be plenty warm and driving at constant speed to have this occur. Any ideas. It feels like something is locking up in the the drive line.
I have a 2001 330Xi, and I used to have the same noise, I change the transfer oil, and that help a lot, right now I have some tire noise about 70+mph. Try doing that thing first. Good luck
Dealer Replaced the right Half Shaft right half shaft replaced - the problem seems to have disappeared TG
same thing with our 2003 325 XI, but it was CPO and dealer resolved by working on the drive and fluids. this info. was helping to us in finding the problem.
