Clogged drains can allow rainwater to accumulate in the plenum tray (at the base of the windshield). The water may leak into the vehicle's interior, brake booster, or electrical components, which can lead to major problems. Our technicians recommend keeping the tray clear of leaves, pine needles, and other debris.Google+

Water enetering the interior- water on the floor, during the winter I have to scrape the interior as well as the exterior of ice/frost--
My dealer checked it out, $300.00 an found drains OK but indiated further diagnostic's would still be on my dime. A 2003 model and VW has lost the SIMPLE knowledge of how to keep the interior of the vehice dry when it rains! I have heard this is quite a common problem in numerous VW products during thew early 2000's
I guess its cheaper for them to ignore the problem rather than a recall, there's always anther sucker down the road. A so called class action suite tuned out to be awaste of time when up against a big corp. such as VW
A VW no more for me, or my friends

Everyone wanted me to repair the heating system because of a wet carpet. These forums really help. It was clogged leaves. This car is killing me! Someone buy it off me!

My car was serviced and the protective shield was removed and never replaced. The car has had electrical problems ever since then. I live in the pacific nw with rain being an issue for the unprotected car

water leaked into the passenger part of the front seat. this was due to the gaskets around the smog filter behind the glove box. I complained to the factory and they fixed it under warranty even though the warranty had expired. There is a trnasmission control module under the passenger seat. The water seeped into it causing the car to lock into second gear. estimated cost of repair was 1000 dollars. The factory fixed it
it for which I was thankful.
Sudden lost of brakes. The service tech stated the cause was a power boost failure in the braking system. No debris visible,
