Wow dude you have more probs than Ive ever experienced with my A4, in last two years Ive had 1 puncture, a rattling heatshield, a leaking rear shock absorber and the footwell full of water. Oh and the ****** idiots at Hi-Q who put the wrong size discs on the front, surely to god it was noticeable that the pad was bigger than the disc face. But all in all its never let me down.
