Model Years Affected: 2004, 2008

Average Mileage: 21,000 mi (18,000 mi - 24,000 mi)


Condensation may develop in the heater case which can cause a musty odor from the heating, ventilation and AC (HVAC) system.  Our technicians tell us the drain system should be checked for debris. In addition, a cleaner is available for the heater case.

    Sour odor, like cheese, DISGUSTING whenever air was on. Worse when a/c was turned on. No Solution yet.

    A musty aroma was evident any time the AC was turned on. The dealer applied a Aircomatic treatment and it appears to have corrected the issue. I suspect that this is something that will have to be done yearly. Obviously not a very good design on VW's part.
