My Megane CC has a leak from the roof glass section
When I press the brake the water comes pouring in onto me whilst I drive.
I know it's not coming in from the Windows,they are adjusted fine.
I can hear the water above my head sloshing around as I turn etc.
Where is the most likely place rain water can enter the roof glass section? I'm thinking it is coming in the through the side trims on the roof and running into the glass roof frame?
Anyone help?

Re: CC roof leak
waterleaks can be very tricky to locate, first thing would makesure all the seals are clean, muck stops them from being waterproof, mine was leaking but a wipe over of the seals has cured my problem.

Re: CC roof leak
best thing i find is bio washing powder is some hot water and a cloth, once dry some silicone spray. cured many leaks on rear lights, sun roofs etc using this method.
Re: CC roof leak
Cleaned and lubricated all seals, still leaking into the glass frame at the drivers side.
It is extremely difficult to tell how it is getting inside the frame.
Every time I drive and press the brake I get covered in water.

Check down the glass roof each side and see if you can see any small cracks in the sealant that is securing the glass roof.
Clean all the sealant with an old toothbrush and run a thin bead of clear silicone sealant down each side, this should seal any small gaps.
Make sure the roof is dry before you use the silicone sealant or it won't make a good seal.
This is the problem i had with my CC roof.
You could hear the water swishing around and when braking and cornering it was splashing down on to the front seats.
I could see couple of tiny cracks in theses down each side and when i poured water down the seal i could see it seeping in the cracks.
Hope it helps.
