If you have the cover than all's you need to do is pull the black weather striping back (that holds it in place) and gently pull the cover off. After I got my 01 Passat and reading this I took a look and it had a few years of gunk in there. I got and 04 Passat a few months after that and same thing. Totally clogged.It's time for me to do this, I'll have to take out the Bentley for help and I'm also worried about all those little plastic bits breaking.
sunroof drain.I know this may NOT be the place for this but after about an hour looking around, I haven't found anywhere else to post. I was looking for a General' area where someone could post a vanilla, starting point for a truly NEWBIE to find their way to the specific place. There is almost TOO MUCH information here!!!!
I have a 2001 Passat station wagon (standard V6 engine) and am experiencing water ingress problems; the passenger side floor was soaked after a mild rain (found the next day). The windows were up tight and the sunroof (which I -NEVER- use) was closed. I did find the info about water collecting under the battery compartment. So, yesterday (Fri), I removed the battery and the battery tray and did find the two drain holes; one almost directly under the battery and the other more to the left (driver side). The Battery hole was filled with damp debris, which I poked out easily. It was encouraging to see that the battery tray was rusted on the right side, indicating the presence of standing water. The drain on the left was clear and the little skirt was intact. So, I felt good that I had found my problem. Today (Sat) we had a short rain. When I went out to check, I found the front right corner of the passenger side carpet had a very wet spot (3" dia). I should mention the car sits at the curb with the right front wheel next to the curb channel (cul-de-sac) so the car has a slight tilt to the right. I don't know where the Pollen Filter is and did not see anything that I could recognize as such. With the sunroof never being open, I'm reluctant to see that as a source of the water but I did look through the posts on that and, being really ignorant of what is where, could not figure out where the sunroof drain tubes are and how to find them. I got the feeling that there are significant differences between all the models within the B5 range so ended up feeling kind of lost. If someone can tell me exactly where the Pollen Filter and Sunroof drain tubes are, I'll be ever so grateful (or specific pointers to where I can see them). I think the 'tilt' of the car is part of the problem but I cannot find where it's coming in.
I know it's long but I've spent several hours looking around here and I'm feeling overwhelmed.
So I need some help.
