Hi all new to the forum and looking for help. Just bought an Aud A4 1.9 tdi 115 sept 2004. Its covered 133k which I know isn't much but the service history is patchy and not with audi Paid £5,500 so it was cheap enough. Question is this, is there a way of interogating the on board computer to see if its had any faults or anything? Was hoping there was some secret combination of buttons which would let me access some info!

The car says nxt service due 5,700 miles but I'm aware that the service light could have been re-set in a second without actually serviving the car at all.

Also states cambelt was changed around 10k ago, is there anyway of proving this or is it a leap of faith?

Thanks guys.
