Rear Sunroof leak not drain tubes
 

yeei another leaking Q7.. HAHA . Ok so my wife and I heard a noise in back on Saturday then the speakers started crackling... I pretty much knew what it was. Sunday we took it apart and found a little water on the bose amp as expected. I pulled the fuse and pulled the amp. We took down the headliner a little and put water across the sunroof and she watched, nothing came down tube or was dripping from that corner. I pulled the hose off and rerouted the bottom so it went straight through bottom instead of too the side to get more flow. I took a hose and ran water across the sunroof and drain seamed to be working fine but we could hear water dripping on the headliner. Then it started dripping from the edge closest to from passenger side from middle to passenger right pillar and leaked down. We tested that a few times and then stopped before we created more damage. Basically i have to pull most of headliner down to see what the problem is. Anyone with experience on this ?

thanks much in advance

That sounds like a leak through the seal between the front and rear glass otherwise any leaks down the edge should be caught by the catch tray and end up going down one of the drain tubes.
Have you looked carefully at that seal yet?

Hi what was the issue, did you have to reseal the pipes or was there something else
