Re: Sunroofs & water in footwell
I've posted this before. Took me months to sort in my 1999 156.
Where the edge of the roof opening folds down, its a double layer of metal, as the sunroof frame is welded to the folded down lip of roof.
The seal goes in this with the flexing of the car body and water gets sucked up into the roof space by capillary action.
You need to run a ring of clear silicone sealant around the bottom of the folded roof lip with your finger, to re-seal the "double skin" of metal.
That stops the water being sucked up into the roof space and it will then drop off from the lip of the roof into the plastic tray and drain....
The roof lining is actually above the plastic drain tray, so there's no way that water "overflowing" the drain tray could jump up into the roof lining, it would overflow into the car itself onto the front seats...
