Cleaning evaporator with ultrasonic A/C cleanerVAS 6189: Audi A8 D3

🧭 Before you start

Fits: Audi A8 D3 (4E, 2002–2010)

Don't miss

• The odour can only be eliminated by cleaning with the ultrasonic A/C cleanerVAS 6189 if it actually occurs in the evaporator.
• On this vehicle, the dust and pollen filter is installed at the fresh air intake upstream of the fresh air blower V2 and does not therefore have to be removed for cleaning.
• The cleaning process takes roughly 15 to 20 minutes and is completed when no further vapour emerges from the outlet hose.

📋 Procedure

1. By switching from fresh air to air recirculation mode, check whether the air conditioning unit evaporator is really the source of the odour. [Note: The odour can only be eliminated by cleaning with the ultrasonic A/C cleanerVAS 6189 if it actually occurs in the evaporator.]
2. Check the plenum chamber and the water drain valves fitted in it and clean these if necessary .
