A search of the forums brought up plenty of posts about leaky doors... but I've got a leaky roof!
After (a few now) nights of heavy rain, the interior light/control panel in the centre of the roof has been filling with water and will then overflow into the cabin from the front drivers side corner. When driving after such rain and cornering, the water will tip out into my lap - nice! Interestingly, even during opposite cornering manouvres it never spills out on the passenger side.
I assume that this is coming through the roof/windscreen seal at that centre point as I haven't seen any water anywhere else in the car but from the outside the rubber seal there looks normal enough to me.
What does this sound like to people - is it a seal that needs lubricating or is there a hidden gutter or something that may be blocked? Do I need to pump in some horrible sealant or - God forbid - have to take the windscreen out?
