What to check on a used 2003 Audi A4
- Fuel system: smell for fuel around the car, watch for hesitation or stalling, and check for a lit check-engine light.
- Transmission: test-drive from cold through every gear, feel for slipping, harsh or delayed shifts and shudder, and ask whether the fluid has been serviced.
- Electrical: test every light, window, lock, the infotainment screen and the charging system; scan for stored fault codes.
- Lights: check headlights (low and high), brake lights and turn signals; condensation inside the housings is worth noting.
- Recalls: confirm each of the 4 campaigns above was completed on this VIN; open recalls are repaired free at a dealer.
