A45 AMG diff problem?

Drive it till it blows up, it's under warranty no doubt.

Seen a few of these and RS3's being battered senseless through Manchester City Centre by "Geysers", might be just bad luck or moronic treatment, they should handle it but they are what, knocking on 400 bhp with massive traction so can see how a diff has a tough life, a launch is the hardest treatment it will ever get, no power to full power in milliseconds, 59k is probably quite high for one of these just yet.

Check the service history to see if / when it had the rear-diff oil changed by the dealer(s). Some have been needing oil changes in under 10k miles and it is a known pain-point.
