I had had an unknown water leak on the drivers side of my 1996 a4 quattro, leaving a puddle of water in my rear and front side. I recently discovered the leak is from the rear left sunroof drain by pouring water through the hole and watching it dribble down the b-pillar along the seatbelt and along the door down to the fuse box.
Today, I took off the upper portion of the b-pillar and pulled the headliner so I could try to pinpoint the leak location. As I poured the water, I could see it literally go straight through the drain hole and down the headliner, onto my head. From the info I have found from other posts, I thought there was supposed to be a hose that drained out the rear end, although I could not see any such hose. Does anyone know any information about the '96 sunroof drainage system and why there seems to be no hose or channel for the water to drain?
