Where can I find info on recalls and technical issues??? My dads just got a 09 Q5 and there's a couple of things I need to check. Also, where would I find Audis official line on using the same tyres with a Quattro. Basically all four tyres are of different manufactures. I was always under the impression that all 4 tyres had to be identical when used on a Quattro to avoid excessive wear on the 4wd system. The cars from a main dealer, so just want to go in with some backup. Cheers.
