I had the pockets of the car with loads of the silica gel packs in them, didnt notice much difference. Mine is still there, not as much, but some of the water on windows. Misting up still a problem.
 
i've not posted much on here but after the responce of my local dealer, not too happy! My windows steam up too, but i'm more concerened about my headlights that have steamed up, i did raise this matter with the service manager about a year ago. He suggested to take a picture of it and e-mail him the pictures or go into dealer and they would do it for me. My car a 06 tdi leon will be due its mot in march and if it fails on the mot test due to lights thats only when they'll possibly be albe to do somthing as a " good will gesture " but the best thing to do would be to speak to seat uk. ( i did manage to speak to another person there and she said with headligts they would have the car in the workshop for 20-30 mins if it didn't clear, seat uk then say to keep car in and remove headlights, to thoroughly dry out then re fit, only if this then fails is there a possiblity of changing them!!! So how many times have you got to drive to your local dealer to complain to get owt done,which is time fuel and a right pain in the ar@e... oh and on the way out the door i got drawn to a demonstrator K1 leon mmmm nice, and the headlights........ starting to steam up!!! so. we're screwed! unless theres a moretti conversion, twin headlight jobbie!!! then we'd get another 1yr warranty.
Or drill small holes in the back of the unit to allow the water/steam to evaporate!

took my k1 to dealer as only one headlights was a problem and they took pics straight away didnt even want to dry them out and booked me in straight away had it replaced with in 4 days :) take it back its a common fault they didnt even contact seat uk they just replaced it. tell them your not happy as the water has caused your bulb warning light to come on and when you switch them off and then on the warning clears
