Audi A6 Avant - Carpets wet on the passanger side

[almondm]

Hi,

I have recently bought a 2001 Audi A6 Avant - it drives great but I noticed yesterday that both the front and rear carpets on the passanger side are rather wet. I was worried that this may be the air-con leaking - is there any easy way to check? I also noticed a small pool of water underneath the car when I pulled away from home - the onboard computer has not reported any problems however and everything else seems ok.

If anyone can help it would be much appreciated.

My A6 suffered the same problem - the front and rear passenger carpets were drenched!
It turned out to be the POLLEN FILTER HOUSING. They tend to crack and in doing so, lift the seal from the bulkhead, allowing water to get underneath and straight down into the footwell.
Audi must be well aware of this problem as the part number has changed from number ending in 'A' to now ending in 'C'.
The pollen filter housing is located on the nearside, underneath the windscreen, and is attached to the bulkhead with 3 or 4 bolts/nuts (it was some time ago when I replaced it!)
The housing will cost around £18 from the dealer.
Hope this helps.
Just for info - there are some purely Audi forums out there too.
