Car had to be recovered today only a day after getting it back from Audi for replacement pads, after putting my foot down at the lights an enormous bang shook the entire car! Turns out that the bearing on the prop shaft had exploded! Sounded like I was dragging a load of tin cans behind me on the way home..I've only done 4000 miles and this happening so soon along with the brake squeal has really put me off, starting to regret not getting a C63 now
