Default Wet patch under Drivers mat

Weirdly a wet circle under my drivers mat, I noticed today when I've come to hoover. I did jet wash yesterday, but the mat is bone dry, even the area around the odd little circle is dry?

As if it's coming up from below, it's an A6 allroad .. anyone got any ideas?

Used to get that in my last Octavia.

It's just a grommet that's popped out.Pull the carpet up.

It's amazing how much water gets in

Hi,
Three possibilities:-
1) Grommet - as mentioned above
2) windscreen seal leaking and water tracking down to footwell (had this once, years ago)
3) you couldn't make the toilet?
Cheers
Steve

VAGs have about 3 to 4 inches of void space under the carpets, in the footwells and under the seats that's just filled with absorbent foam.

Guess what happens if the car rains in...these fill up and you won't know a thing unless you have a Bluetooth unit under the seat...which goes for a swim and shuts down the entire multimedia system (screen dead, radio dead, nav dead, cd dead etc). You can have a few litres under the seat and not know a thing!

Water can get in through many places, as listed above, also include door seals, door cards, blocked door drains (front and rear), bulkhead drains blocked, sealant on bulkhead seams cracked; either way water ingress always find the lowest point...the footwell.

Disconnect battery (to avoid a SRS light from the seat airbags being disconnected) Remove driver's seat (heavy b*stard thing), sill panel and pull up carpet + foam and take a look. Give the foam a good squeeze to see how much water is in there.

If its sodden, its a bitch to dry out. On some wet VAGs I have had to remove the entire carpet and leave it air for the week next to the space heater.

Or the CCU fails due to flooding (under the foot well N/S), windows and or central locking problems.

Taste it.

I'm serious, dip a finger in and put it on your tongue.

If it's sweet, it's option 4: your heater matrix has gone.

Could be a leaking seal in behind the door card.
Seat,s are renowned for this . I had it on a Toledo.
The seal at the bottom perishes and water running down the side window leaks between the door card and the plastic sheet behind it.
