I have a 2016 1.6 TDI DSG estate with A/C. There is often a damp smell in the car and the air blowing out of the dashboard vents feels humid. The steering wheel feels clammy sometimes too. Sometimes there is condensation on the inside of the windscreen above the windscreen vents - as if humid air was being blown onto the windscreen. This seems to improve a bit if the AC is switched on, but not entirely. There is no evidence of any water inside the car (damp carpets etc). I wonder if there is some water drain pipe somewhere from the ventilation system which is blocked. The AC, the fan, the heater etc are all working ok - there is just a often this humidity in the air. This was even evident during our long summer when it didn't rain for months - so I can't believe it is rain related. Any suggestions gratefully received. Thanks - Joe

Have you had your AC checked for leaks?

Have you replaced the pollen filter?

Could be the aircon drain hose is blocked or failed. If you put air con on max for 20 mins there should be drips under car from drain hose. If its dry then its either blocked or become unattached. The underlay of the carpet acts like a big sponge so you need a lot of water to get carpets soaking.
