Odor from HVAC vents on Volkswagen CC

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.

2010 Volkswagen CC 65,000 mi,
I bought the 2010 CC to replace a 2002 Volvo S60 2.5T. I thought I was in the clear with having to constantly change light bulbs, but I was wrong. Like the Volvo, I am changing a light on the CC every other month. Don't buy at dealer any more as they charge 3x's as an auto shop + $25 to install. Really! Everytime I turn on the AC it smells like my father-in-law just took off his shoes. Had to replace the battery at 55k, left me stranded 2x's. I have had the Volvo for 11 years, 200,000 miles - not once have I replaced the battery. Just last month took in for battery, now check engine light came on again. I took to dealer and it is the manifold. Seriously, a $35K so called luxury car, and this is what German engineering has come to. Extremely disappointed.
Odor from vents when a/c is turned on but seems to happen with just any start up for a period of time.

Same funky ass smell whenever the AC is first turned on. And now the damn interior lights stay on the entire time I'm driving the car. Dealership wants to charge $815 to replace a "module" that will fix the light issue.

A very bad smell coming from the air vents. The dealership replace the air filtor and that help for awhile.

I have had this happen at the end of every season. I have had it treated twice now and they say it is just Florida. Bull. I have had tons of cars in FL and none have ever done this.
