What to check before you buy a 2001 Audi A4

A useful visit to this page takes five minutes. YearTell does not score years and cannot see the vehicle in front of you.

  1. Look up the VIN for open recalls at nhtsa.gov. This year has 3 campaigns on file below.
  2. Electrical. Have a shop scan for stored codes and check battery, charging and any warning lights that stay on.
  3. Brakes. Have a shop check pads, rotors, fluid and whether the pedal feels firm.
  4. Engine. Have a shop check for oil consumption, coolant leaks, rough idle and unusual engine noise.
  5. Skim a few owner reports below for Electrical. Look for the same symptom repeating.
  6. Take that list to a mechanic. Do not turn the complaint total into a score.
