I get these symtoms too tankslapper. You think you'll get a new diff?

Derek, what was your symtoms and many miles your car got?

the car did clonk at little with no drive at low speed, there was found to be more movement on the diff than another m3 the garage compared it too, mileage was 38k, Big difference in the driving noise level and s6 changes

I finally solved the knocking noise.

The piston in the front suspension was knocking.

Remedy was to adjust the front coil overs up by 1mm

spend months trying to solve this, and it only took 5 min to sort it.

Now working as new.
