water damage

water accumulating in rear right passenger floorboard windsheild seal replaced andsunroof drain cleared,any information appreciated,thanks

Right rear passenger door vapor barrier needs to be resealed no doubt. Would make sense to do the left barrier too.

+1 I resealed mine twice and it still leaks a little, but only during a driving rain when parked

Dunno but maybe it was resealed badly?

If that's the case, these threads may help:
- How the vapor barrier works (1) & the problem with front & rear door vapor barrier adhesives which allow rain water to wet the carpet (1) (2) (3) (4) (5) (6) (7) & what adhesives to buy (1) & what sizes for the adhesive beads (1)

Do you have a sunroof? It is highly likely that the drain lines for your sunroof are clogged. Now i am no expert but i know that There are ducts that channel water down from the sunroof area and, on a E39, thru the B pillar and then out the bottom of the car. These ducts frequently become blocked on my car and water mysteriously appears on the rear floorboard when there is heavy rain and sometimes when i go thru a high pressure car wash. Any technician who is aware of these aqua ducts can blow them out for you and there should be no more water damage. For awhile at least

Prob so, but leaking is minimal now - only in a very hard, driving rain - so I'm not getting into scraping all that sealant off and starting over again unless it gets to leaking more frequently.
