Question about 2003 Volkswagen Jetta TDI
I am getting water when it rains. It seems to be only on the drivers side front and back floor. I see several comments or complaints in regards to this problem. I am Costa Rican we have lot of rain falling every day as a tropical forest country and I would like to know if you can help me with this kind of issue.
There are drains that go from the factory sunroof down the frame and come out in the door frame. If you open your front driver's door and look at the forward part of the door frame you will see what I am talking about. Make sure these drains aren't clogged. If you can find something stiff enough to force down the drain, but still flexible enough to go through all the turns and not poke through the tubing you can push out any gunk. With the sunroof open you should be able to see the holes around the edge of the sunroof frame. These drains are why there are fewer problems with the factory sunroof versus an aftermarket one. Even if some water gets through the seals it has a place to go. Other than that the door seals are really the only other place prone to leaking unless there is some hole in the floorboard. But that would be strange.
There is one more longshot place. In the front drivers side under the dash there are some holes to pass through wires to the engine bay. These holes have grommets that keep water out but if someone did some aftermarket work on the car they may have added wires here and not sealed everything up tight.
Since the water is on the drivers side only I'd start by taking a quick look at the door seals on that side. The driver's door is a good candidate for problems since it is used the most. Also, if the seals are bad you might be able to notice more road noise when driving. Goodluck.
