    Water on the floor in turns

    Have any of you experienced water coming from the lower vents on the center column onto your feet when taking a turn. I know with other cars it would seem to be an evaporator issue but the AC seems to be working fine with no smell or issues. Just curious if others have had this problem. I am in Fla where there is a lot of humidity so not sure if that could cause it as well.
    Thoughts?

    This sounds like the cowl seal. You should notice it more on the passenger side. A little odd that you may be noticing in on the drivers side.

    I was thinking it might be condensation inside the AC ducts? When i was in Florida this summer and it was hot as balls, i didnt notice any water coming from the lower vents, but i did see ALOT of condensation on the upper vents and fins and whatnot. Had to wipe it all down and turn the ac up and roll down the windows...

    I'm thinking this, too. There's a condensation drain that is somewhat to the right of the pass side center footwell duct. It's basically a flapper that could get stuck or plugged and cause the condensation to pool up and drain out the ducts.



    The only quock pic I could find is of one of my B5 S4 projects. The hole with the daylight shining through is the approximate location of where the drain is located. You should be able to see it from underneath the car. Maybe. . .

    Its definetly the condensate building up and the drain is clogged...i had the exact same problem in my RS6 and every Audi for that matter. There is a drain tube that can get clogged...its pretty much exactly where the pic above shows it. I had dealer clear it under warranty though a year or two ago.

    Ok, I THINK i found the sunroof drains on either side of the lower A-Pillar/door hinges - my drain tubes are green(?) and I haven't tested them for water running thru..
