2003 Audi A4 1.8T Avant quattro AWD 4dr Wagon (1.8L 4cyl Turbo 5M)
This car has had so many electrical problems I can't even remember all of them. Parking lights each went out one at a time requiring separate visit to dealership for each one. Bad design caused moisture to corrode the contacts. Sunroof was opening on its own and dealer finally found problem after 2 years. Headlight alignment warning light came on, was fixed and now is coming on again after out of warranty. Stereo speakers are shorted out and intermittent. Also, back window just fell out one day. Engine is good but even it had sludge issue and took three days to repair. Hood latch gets jammed and won't open. Cupholder problems - not big enough and won't even pop out of back seat armrest.
Corners well. Reliable engine after I got the sludge problem fixed. Looks mean. Roof rails. Plenty of room in rear storage area, especially with seat folder down. Xenon headlights.
Improve the electrical system reliability. Make it easier to recline the seats. You have to struggle turning a wheel to adjust the seat backs.
