What to check on an Audi 100 with this engine

  • On a gasoline engine, check the oil consumption, the timing chain or belt and, on turbo engines, the turbocharger.
  • Test the clutch or the automatic transmission from a cold start and in the low gears.
  • Compare the odometer with the readings in the service records and in the VIN history report: a big gap means the mileage was rolled back.
