I have found the comments useful on here so for what its worth I have added my experince. It took a while to realise that water was getting in, the penny didnt drop with condensation on the inside until I saw some drips inside, then I checked the front footwell and the carpets were soaked. Didnt notice as it was under the mats. I have attached a couple of pictures.
No garage at home to check things out away from the weather but cleared the pan roof drain holes as described on the forum and all looked normal. However still leaked so as its not the best time of year to do this stuff the main dealer dealt with it. The franchise had changed so the company was not the same as I had bought the vehicle from. Anyway the panoramic roof cassette cost inc fitting was £1661 plus VAT so it has cost me £1993 with a two year warranty. So I have two years to make up my mind other than that the Yeti must rate as the most practical vehicle Ive had.
Anyway I hope that what I have desribed might benefit someone else.
I have complained direct to Skoda but not holding my breath!!!
