Skoda Yeti leaking sunroof. My wifes’ 2016 Yeti 2016 L&K started leaking water into the drivers’ footwell. After much investigation I removed the trim and lifted the side of the roof lining so i could see under with a torch. I found two problems. Firstly the plastic adapter that fits under the drain channel hole was leaking slightly at the bottom where the rubber drain pipe fits up into it. A quick clean and waterproof mastic inside and out sorted that. Secondly, and by far the main leak, was the rubber seal at the centre front was failing and allowing water through it, into a 10mm gap between the car body and the sunroof tray that is supposed to be protected by the seal and down onto the roof lining, then down the drivers A pillar and into the footwell. I peeled up and lifted the seal just enough to expose the gap all the way across the front of the sunroof tray and partly down the side and filled that with the mastic too, smoothing it down and allowing it to dry a few hours before refitting the seal in place. This allows for any water ingress to go into the sunroof tray and into the drain channels as it should. Finally with the sunroof closed I used Gummy Phledge to treat the rubber sunroof seal all the way around a couple times. I will repeat this seal treatment each autumn too. That was 4 months ago and I can report no further water ingress. All in all a cheap fix that worked for me and that is doable with few tools and limited mechanical knowledge. Hope this helps.
