When you opened the sun roof was there water in the channels like too much specially the wind deflector mine was drenched when I opened it.It Has been raining overnight but has stopped now. Before I went on a drive I checked and the inside was perfectly dry. I went on a short drive around roundabouts etc and there were no leaks. I then slid the sunroof fully back and checked the channels and there was no water. I closed the sunroof fully and went on another drive with no leaks. I checked the sunroof seals and they were all soft and pliable and I can't see how water can get in.
