Come to find out that the M Diff wasn't completely broken in (The car has 13k miles on it so I find that hard to believe). So they changed the differential fluid with a different kind and now the noise is no more. The dealership said that BMW has sent out a service bulletin on the matter.
Has anyone else ran into this with their M3s?
yes and because of this forum i was able to quickly resolve the issue at the dealer. they changed differential fluid that contained an additive whatever that was and the problem dissapeared.
