Water puddle behing passenger seat on doormat

[888nik]

I have problem with my Superb, when I wash car I get puddle behind passenger seat.

 

I know for water ingriss, I dont think thats problem, because I have already(like 5-6 years ago) prevent for happening.

 

So all lights working except when I open rear door sometimes it doesnt show on maxidot.

 

Need help figuring this out...

Sure sounds like some kind of water ingress to me...

These cars leak like sieves.  Some of the places they leak from:

1) Pollen filter housing (front left of bulkhead)

2) ECU housing (front right of bulkhead)

3) Sunroof drains getting blocked

4) Door carrier panel seals

 

Good luck working it out.

1.)This was sorted years ago, and Im controling from time to time.

2.)Seems good to me.

3.)Doesnt have sunroof.

4.)This could be problem, Ive read some passat b5.5 owners had this kind of trouble.

It isnt too dificult to take them off, so I will begin from that point.

Thanks for helping!

Don't take off the carrier panels themselves (as that obviously breaks the seals) until you are sure, but you can remove the trim panel.  There are some videos on repair technique.  I've used Shell Tixophalte in the past on my old Skoda, which worked well.

Certainly if anyone has at any time been inside the door for repair of lock module, window motor, etc, you can likely expect the carrier panel seal is broken and leaking.
