Leaking rear passenger door in 2003 passat

My 2003 passat had a puddle in the rear drivers side foot well. I sprayed water on it it and it seems to be leaking from the bottom of the door. all around the window is dry. Has this happened to anyone else?

It could be that the plastic sheet in the door is not sealing well. The door allows water to come in past the window on the outside, and run down the door on the other side of the plastic sheet. If the seal is not good, that is where your water could be comming in.

The other possibility is the rubber door seal - does it look good, or have a hole or gash in it?
