HVAC, Unpleasant Odor
Unpleasant odor is coming from Heating and Ventilation system. Odor mainly occurs after vehicle has been sitting
(unused) at least 5 hours and within 20 to 60 seconds after vehicle is first started.
Note:
This Bulletin may only be applied as “one time only” for vehicles with the complaint and within 12 months
of the original vehicle in-service date as stated in the Warranty Policy. (See section 1.3 General
Guidelines/ Start of warranty period)
Any future complaints will be at the expense of the customer.
Technical Background
Condensation, which is a normal condition in all A/C systems, can cause a musty odor. If the odor is noticeable in
the vehicle when the engine is not turned on, the cause may be mold and mildew in the passenger compartment,
and not be related to the A/C system. All other possible sources of the odor must be investigated before this
bulletin can be performed. Before proceeding, consider the following:
 The evaporator housing drain must be open and free of debris.
 The cabin must be sealed with no water ingress into the passenger compartment.
 The plenum drains must be clear and free of debris.
 The pollen filter must be clean and free of moisture
Note:
The condition of the evaporator is a normal characteristic caused by outside influence via environmental
conditions. This procedure is not to be claimed under factory warranty and only to be claimed under 1SP
within the first 12 months of the original in service date for customer satisfaction purposes only.

Technical Bulletin
Production Solution
Not applicable.
Service
Contaminants are effectively neutralized using the AIRCOMATIC™ II Ultrasonic Climate System Cleaner (VAS
6189A) or AIRCOMATIC™ III Ultrasonic Climate System Cleaner (VAS 6189B) and AIRCO-CLEAN™ Ultrasonic
HVAC Treatment (30208). All other cleaning methods are no longer permitted.
There must be an original customer complaint of specified odor symptom on repair order for this Technical Bulletin
to apply. Adding this procedure on to another procedure is not permitted.
Tip
If vehicle is a Touareg or Phaeton with 4 zone climate control, the rear A/C unit is to be treated as well. Repeat
procedure for rear A/C unit.
Cleaning the Air Conditioning System:
Tip
 No one must be in the passenger compartment.
 Observe the instructions on the cleaner and the cleaning fluid
 The vehicle must not be exposed to the sun
 Remove the pollen filter in the passenger compartment (if equipped)
1. The vehicle should be cool, if necessary cool it down with the air conditioning to about 72°F
2. Dry the evaporator by running the ventilation (air conditioning "OFF") at the highest blower level for about 30
minutes.
3. Remove the activated carbon filter or pollen filter according to the repair manual. Close the cover on the AC
duct without filter.
4. Open all vents, align them to the passenger compartment and select them with the control panel.
5. Leave the air conditioning switched off. Set the fan speed to level 1 and switch on the recirculation so air is not
brought into the vehicle. Run the engine during the complete cleaning process or switch on the ignition and
connect a battery charger.

9. Start the cleaner (VAS 6189B / VAS 6189B), the warning light "Cleaning" comes on. Close all doors and
windows.
10. After about 15 minutes the cleaner switches itself off automatically.
11. Open all windows and doors.
12. Continue to run the ventilation for another 10 minutes.
13. Remove the machine from the vehicle.
14. Install new activated carbon filter or pollen filter.
15. Switch on the air conditioning and run in recirculation air mode until condensed water is discharged under the
vehicle.
Tip
By leaving the controller in recirculation, this allows cleaning agent to be flushed from the ventilation duct work.
