Wet Carpet

A6 All/ S6 All
#1

Just went to vacuum my car before going to wash it, and our vacuum is now fucked thanks to the water it sucked up from the passenger side front carpet before I saw it…

Car has been sitting for 11 or 12 days, been driving the truck around. Has BARELY rained here at ALL since (in a drought, water restrictions in place due to severity). Not entirely sure where it is from. Any common drains that get plugged/leak into the cabin in these? I know of the ones that were notorious with my B5 chassis, but haven’t had a chance to look into these ones. It’s a pre-facelift car.

Thanks!

What year A6/S6/RS6?

I have the problem in my 2003 Passat. One time I was parked on a sloped driveway in a storm, and found 2 inches of standing water on the passenger side rear floorboard. I still haven’t found the source, I had suspected sunroof leak, but the overhead fabric was dry. Maybe it’s a bad seal on your roll-down window? Try pulling the interior panel off your passenger door and check for evidence of water in there and/or a plugged drain hole in there.

Btw, I live in drought country too (nor-cal)

Passenger side front floor for me, 2007 S6. Thinking it MAY be the sunroof drains, as the front ones run down the A-pillar I was told? But more likely something from the front windshield/firewall area.

Let me know if this solves your issue…

This is from another thread of things to check…

  1. Blocked sunroof drain
  2. Blocked holes in the chasis underneath causing water to bubble up through the floor
  3. Leak around the pollen filter?
  4. Blocked drain in plenum chamber? (I think this is more an issue with the C5 model)
  5. Rear wiper pipe leaking (you would smell the fluid)
  6. Leaking seal to bonnet release
  7. Door not sealing properly

Should also add blocked AC Drain

Deffinitly check all the usual spots. If you have an air hose and a compresser the clean and check can be made quicker and easier with an air attachment and blowing compressed air into the drain lines. Even if there is something small lodged in the lines a good flow of compressed air will help move it along.

If you want to look deeper pull the passenger side kick panel off then you can also pull the door lip tray off. It just comes right up.
once you have done that you can start to pull the carpet more back and start looking for leek points. All of the body water drain lines are going to be light green. So when you see one you can follow it and make sure its not clogged

Mine (C5) was coming in from the pollen filter due to wiper cowel not fully seated along windshield. C5 pollen filter is basically open and exposed (silly design imo).
