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.

    Large amounts of water on drivers side floor.

    Cleaned out drain in driver door hinge, no longer seems to be a problem.

    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

    I bought my Passat Wagon used from Hilltop Motors in July 2010. I noticed occasional water on the passenger side but didn't know where it was coming from, it was intermittent and didn't seem serious. Since there were so many ongoing issues with the car I didn't get this addressed. Recently it became much worse and before I got it into the shop it flooded during heavy rains on the passenger side doing damage to my electrical or computer system. My car has been in the shop all week while they try to dry it out and see if they can repair it. Its not looking good.

    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!

    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.
