This service bulletin provides step-by-step instructions for cleaning the air conditioning system in Audi vehicles using the Aircomatic® II and AIRCO-Clean® ultrasonic cleaners. It includes required parts, setup procedures, and warranty conditions. The procedure is limited to once per vehicle within the first 12 months and requires an original customer complaint of the specified odor symptom. The bulletin also notes that pollen filter replacement is not covered under warranty during this procedure.
The odor mainly occurs after the vehicle has been sitting unused for at least 5 hours and within 20 to 60 seconds after the vehicle is first started.
After about 15-20 minutes, the treatment stops automatically.
