Hi, I’ve had a whine from the rear of my car for a while now and didn’t think there was much i could do. I found a guide explaining how to change the rear dif oil here Audi area: Audi A4 (B5). Rear Differential Oil Change
Should be pretty similar to the s3 I would have thought. Anyone done this and fixed the annoying whining noise?
Also what oil do Audi recommend?
