E46 M3 Diff Problem...
a friend was wondering if any of u E46 M3 owners hear a clunking kinda, or any kinda noise, from your passenger rear corner when turning at low speeds? was told by a bmw tech that its the diff making the noise cuz its not warmed up yet, but that still seems weird to me.... just wondering if anyone else is experiencing any noise when turning at low, i.e. 2km/hour type of speeds...

I've heard of this a lot. I had the same noise but not at turns, just coming to a stop. Here's a good thread form another forum that deals with this same issue:

This sort of thing has been discussed there a lot.

Good luck *th-up*

I don't think that will be necessary. I think proper warm up should make the problem dissapear. All of the mention I've heard of that issue are from new M3 owners, the problem should go away. If it doesn't, then yes, you'd have to do a replacement, hoping that the problem doesn't repeat itself.
See if it happens with proper warm ups. The way I do it is, I don't go over 3.5k untill the lights have all disappeared, after that she runs real smooth. If I'm in a hurry and don't warm up properly there are always weird noises of some sort (that eventually go away) and the car doesn't run as smoothly.

yeah it does go away after warm up, so i'll talk to the the stealer and see what they say....

Yup, I had the same low speed groan while the car is still cold. I got the diff oil changed and everything is fine now. There is a STB out for it. The dealer should know about the problem.

yup sent to maranello, and it was fixed, for now, we'll see how it goes!
