    The leak could be anywhere.
    The water is just sitting in the rear footwell because this is the lowest point of the car

    Pollen filter housing seal, no? Comes in through the A/C vent under the passenger seat iirc.

    happens a lot of passats, there's a drain in the battery holder under the bonnet, this gets clogged with leaves and other rubbish causing the battery housing to fill with water. This overflows into the vent intakes on the scuttle causing the water to come down the vents, exiting through a vent underneath the front seat.

    If you lift the battery out of its holder (i'd advise disconnecting it obviously, since its wet), you should see a pool of water at the bottom. find the drain hole and clear the gunk out. A few people i know have even drilled a few more small holes in the plastic so it won't happen again.

    The blocked drains usually cause water to get into the drivers side.

    I would check the seals behind the door cards on the passenger doors.

    It can also come in around the pollen filter housing.

    I would get it sorted asap though as the convenience control unit is under the carpet in front of the passenger seat and they don't like water.

    Covered this issue in a thread I wrote a while ago. Few pics illustrating just how much water can collect in the plenum chamber.

    As barry said about checking the door cards is a good possibility.
    If you look at the bottom of the door there are small drain holes to let out water that gets into the inside of the doors. These my be slightly obscured from view by the outer door seal but this isnt what blocks them. Its the wax/grease from moving parts inside the door that falls down and clogs them. If you remove inner door card and notice the soft adhesive seal is half rotted then this is the problem. To cure this clean off the rotted seal and fix back the door card with weatherproof silicone sealant and clean out the holes.
    Had the same problem on a Seat Leon and also my brother had it as well on his Toledo.

    +1 on this.

    Only thing is that the front passenger well (under front passenger seat) will be full of water as well, which is bad enough except for the fact that this is precisely the location which VW chose to locate the CPU, the electronic "brain" of the Passat. You may be lucky and find that the box in which it's housed has not leaked yet, but i doubt it to be honest, are you experiencing any "strange" electrical problems? (windows opening of their own accord, car locking or opening itself?)

    Pain in the bollocks and expensive as well.
