Hi All

I have a 2001 Passat estate, 1.9 TDi 130. About 2 weeks ago I noticed a couple of inches of water sloshing about in the rear passenger footwell. I assumed something must have been leaking, like a door seal, but they are all fine. I emptied the water and am now left with damp carpet to try and dry out.

It appears that as I soak up the water and leave it damp for natural drying, the next day there is a bit more water there. Does any one have any ideas where this might by coming from? Is it anything to do with the two rear facing "tubes" under the front passenger seat? Is this part of the heating/cooling system?

Any suggestions would be most welcome!
