Yes there is. The drain should come down from the heater core area (behind the glovebox) and down under the car. Yours is either clogged, or for some reason has been pulled off the core, so that water just flows from the heater core drain nipple directly into the car.

This is a common problem with your shape A4, pre 2001 A4s and old shape A6s. Rain water builds up in the area under the bonnet where your battery is. This can be accessed by removing the long black trim under the windscreen covering the battery. This area has two drain holes with small rubber tubes on it, these tubes get blocked over time by leaves, dirt etc. They need to be unblocked, and the tubes can be completely removed (and left off). This is much easier to do underneath the car but at least one can be done from the top. Its under the battery though. Be aware when you disconnect the battery, you will lose your radio coding.
It needs to be done though as if the water is coming in the car then it must be high. The water has most likely damaged your convenience control unit (electronic control unit) under the carpet of the footwell, this controls the failed electrical items you described. The water can cause further problems, electrical as it submerges the battery! And brakes as the brake servo can **** the water in causing many problems! Well worth getting it out sooner rather than later. Hope this helps and hasnt scared you too much. Good luck

SOURCE: Water in Passenger footwell

Tracking water leakage in cars is often not easy. However, in your case, I would start with the windshield. Was it recently replaced? If so, the seal might not be fine. Check the windshield rubber trim cover that runs around the top and bottom of the windshield to see if it is coming off from the frame of the car. It doesn't take much for water to get behind it if it is even slightly up.

While you are doing that, check around the top of the door frame. Many a time, water will travel down the contour of the door by the hinges and enter the footwell area if the rubber gasket has been compromised in any way.

Finally, check to make sure that the firewall of the vehicle does not have any rusted hole or improperly installed rubber bushing or gasket on the firewall that could allow water to run along any wires or cables there and trickle into the vehicle. I hope I have been able to help you with this problem. Good luck.

SOURCE: water leaking in on passenger side footwell .

Hi, the water entering the passenger side could be either due to a leakage in the drainage tray at the bottom of the windscreen or a leakage through the window of the passenger side. Remove the carpeting and try pouring water on the windscreen to check. Also remember to leave the doors open when parked in a safe place to allow sunshine and air to dry up the interior. Cheers

2003 passat alarm keeps going off unless i take the fuse out for the remote locking and use the key,sometimes drivers door display shows

Check your passenger footwell for water ingress, this willbe coming through the pollen filter housing in the bulk head, passing over allyour wiring to the convenience unit under the seat, get there in time and save yorself the cost of a new control unit and hope its just a wiring repair. This is a well known fault with VWG and they will gladly give you advise on how to prevent it happening again.

Passenger footwell fills up with water after rain. Notice thin line of water? running down middle of carpet directly under dashboard. No other signs of water/moisture in car. Other than replacing...

IT sounds like the screen BUT check the vent under the w/screen as the vent is for the heater air into the car but it has 2 pipes 1 down the left hand side and comes out under the gaurds ,and the same for the right hand side so make sure is clean by putting compressed air up there and blow out any dirt or what ever ,other wise the w/screen the answer,.
you can also put the water hose in either side of vant and see if the water comes in if not WELL..

Leaks on inside Toyota Corrolla on the passenger side

It could be water condensing from the A/C and dripping onto the passenger rug. Check under the passenger side dashboard, above the footwell, for the drain pipe from the A/C. If it's loose the water may leak into the footwell when the A/C is running. Should be reasonably easy to fix.
