Audi Repair: 2001TT Roadster inside windshield fog,ice, wet areas, dampness

Question
for the last month my inside windshield,windows and rear window is always foggy. The inside  windshield was iced up once. The inside of the car has an odor. Th carpet is dry, but the inside if the trunk is wet with moisture. What do you think the problem is?

Answer
I think you may have a leak in the car, are the carpets really dry?  It sounds like water may be getting into the passenger compartment, and this causes the dampness inside the car.  Feel under the carpet and check for wet areas.  If the trunk is wet, check the seal and around the rear lights.  See if you can find where water is getting in.
