Hi James, all fixed now mate but thanks for asking. It was the os reverse and break lights, obviously it wasn't the bulbs as that was the first thing checked. Now that I'm on here do you know anywhere that I can get an os rear break caliper, I need the full caliper, a repair kit is no good as mine is too far gone, that's according to my mechanic whos also a good friend so he's not pulling a fast one. He's trawled the local breakers today (around the Newcastle area) and all suitable Audi's have been stripped. He's going to check the part numbers because he thinks a ford galaxy or a vw sharan may fit. If you know anywhere else though that's cheaper than whats on ebay please do let me know. Thanks.
