Servus, I’ve had really bad sounds on the rear axle since today, this morning on the way to Stuttgart there was nothing (about 80km from home) then when again 20 km drive, there was still nothing to hear, but after that we drove into the parking garage, it started to squeaky or what it is, you hear every floor shaft or curb.
