C63s coupe - diff issues
Don't think this applies to you though since it was on sedans built before the coupe had been available, and the quick VIN search done by the dealer should have brought this up if it were the issue.

I don't drive the car hard or do anything stupid in it, not sure why this keeps happening.
Also my exhaust rattle really loud between 2-3000rpm, it's from the internal valves but again MB told me there is no solution to fix this and they won't replace the exhaust as the new one will end up with the same issues. I'm starting to get the day I bought this car!

I have the same issue Elctronic rear axle differential lock inoperative. The MB cant find in the system that the 3000kms service was done so therefore they are trying to charge me to get this fixed.
When did you start getting this error? I have 26,000kms?
