Hi, just joined forum so apologies for late answer. If you haven't already bought one, I have owned an a4 cab auto for 4 years and love it. Some early models had problems with auto boxes but Audi sorted it by the later models. You're right about the diesels, I was put off buying one so bought a 2.0 petrol, these are much better and stronger than the 1.8. The Multitronic is fine if you keep it serviced. It doesn't have gears like the DSG gearboxes, it is just one gear, if you put it in manual mode or use the paddles, all it does is move to rev (engine revs) range higher. My son calls them a pretend gearbox! Fantastic cars though.
