Had soggy carpet in my Cinq recently, after a lot of messing around I found water was coming in through the grommet the speedo cable was coming through, and at the bottom front corners of the doors if it was left parked pointing down. This was coming in UNDER the seals, not over them.
I also had come of the cloth mush stuff which would have been the sound deadening/cushioning at one point.
