My 2000 Passat with 22K miles has the most bizarre water leak.
It is only in the rear passenger well.
There is *NO* evidence of water from ceiling, sunroof, on walls or anywhere.
It is clear that is seeping up from below since the padding underneath the rug gets squishy before the rug is actually wet and occurs even after a night sitting out (in the rain of course).
It is *NOT* the drain holes at the bottom of the door as I have cleared these.
Obviously not from A/C condensation as A/C not running in winter (and not working anyway).
A few months ago I got scratched on the passenger door but small dent and cosmetic damage (I have not had this fixed yet).
I have called the dealer but I get the sense they will just start pulling stuff off - help me be an informed consumer!
Thanks (writing from Seattle so help soon)
