Just bought a 2000 2.7T with 42k on it and when I came outside this morning I had condensation on the fron & back glass?

All windows were closed tightly?

Any ideas?

Moisture in the car, windows down last time it rained.

Apparently, it's not all that unusual. My dealer attributed it to the powerful nature of the A/C units, but didn't really have a solution other than to raise temperature levels. He initially said you could close the upper vents above the dash, but that doesn't seem to make a difference, as you'll notice when from the location of the condensation build-up, which is probably just to the left and right of center windshield. If it makes you feel any better, I'm seeing it much less now. Raising the temprature just a couple of degrees does make a difference.

seeing the codensation. I would complain to whomever sold you the car and get them to deal with it.

Common causes are:

- plugged drain tube from the sunroof

- a plugged/disconnected/leaking drain tube from the air conditioner condensation drain

- <A HREF="https://forums.audiworld.com/a6/msgs/423749.phtml">plugged drain holes near battery</A>

- pollen filter tray seal (thanks, 02A6CVT)

- a leak around a windshield

- bad weatherstripping (even in the trunk... check the spare tire well for water

- a small leak in the heater core or hoses.

Fix it before winter, or you may find ice forming inside the car and raining down as the car warms up.

I had 5000 S, then A100, and now A6-the first two did not have any condensation ever, this one, I have to keep A/C on even when I do not need it, say +10-+15 C just to keep it dry inside...
Another place for water leak is cabin air filter (polen filter) tray seal-poor quality, I had leak there, wet carpet on passenger side.

I have about 1 inch of water in the spare tire well from time to time. I seems to build up from the rain. There looks to be drains in the bottom of the well but they don't seem to be working. I haven't checked to see if the water is still there in a while. No rain lately.

The problem is probably the trunk weatherstripping.

After work yesterday, when I got in the car it smelled like a wet dog? I touched the passenger side mat and it was soaked, I mean at least 3 inches of water were in the thing? Where's the leak coming from?

I'm ready to sell and I've only had it 2 weeks!
