Diff Issue

Hi guys, I have a weird problem with my car, I had to get the car towed home today, because everytime I turn either right or left I hear a massive clunk/banging noise from the rear, but it doesn’t do it when I drive straight.
is my diff gone or is it say an axel? Has anyone has similar issue?
I got quoted roughly 10k aud for a re-manufactured diff for Mercedes with install.

do you guys reckon it’s the diff?

Could be but did you have any dash warnings about your electronic diff being inoperable in the past? Any burnouts or doughnuts lately? What year model is your car and which Mercedes gave you that quote that's way overpriced. Brand new diffs are 10k from dealers.

FWIW, the e-diff wouldn't engage just driving straight at moderate speed. It would if you gun it and the rear wheels struggle for traction. Similarly it wouldn't really engage if you are turning at parking lot speeds. So exactly what kind of driving are you doing when it happens? Not sure if you wanna risk it, but does it also happen going straight when you peel off like you stole it? Preferably with ESP/TC off so the traction control doesn't disturb the experiment.

For technical background, the e-diff has a clutch pack that engages whenever it's starting to lock the differential. This happens mainly under hard acceleration and during spirited cornering to send torque/power to the wheel with more traction, for example the outer wheel when cornering. If it happens whenever you are turning, regardless of how aggressively, then it sounds like the differential gears itself might be toast.
