I know we have heard it all before, Have found its my sunroof leaking, now im taking my roof lining off to recover it soon anyway so thats ok.. but has any one every effectively fixed leaking sunroofs and where do they leak from? Do i need a new seal or some description?
:smiley:

Water will always get through seals like sunroofs and door weather strips, its the drainage that stops the water from entering the car.
Open the sunroof and pour water down the channels and you'll see it rolling away through holes at the front which go down the A-Pillar post. The water should collect at the bottom of each wheel arch. Not like my old Mk2:

Water was clearly coming down from the headlining so I used the softest welding rod to push it down the drain hole to see if it was blocked and initially became very confused! Removed the A post trim and found the drain pipe had come off. Easy fix.
If your drain holes are blocked then use gentle compressed air down the holes to avoid the pipes popping off. As for the seal, if its not split or torn and appears to make a good seal then it probably is stopping more water getting in, its getting the water out that is more likely your problem

unblock drain holes as above, also vasaline the seal round the edge of the glass, mine recently leaked a tad, the vassaline trick solved it, this was 6 month ago and no more condensation or water in my sunroof

Airline and 1.5m of 4mm poly tube, blast that crud out of the drain pipes :smiley:

Yeah I got an airline at 40PSI and blasted mine out, sorted it right out. I was skeptical but it worked. Don't go too high with the pressure though.
