Just want to throw this into the list of possible water leaks into the cabin. Got the windscreen pulled out to remove a heap of rust and replace all the seals. This removed the great majority of the leaks.

After discovering water still leaking into the cabin, I found, by a few tests, it leaking through the door seal. It ran down between the roof and door to the side mirror, then through the seal, down inside the door, to thebottom part of the seal and pooled at the bottom of the cabin. The seal got swashed by the opening and shutting the door. Will cost me 88 bucks for a new door seals at my local LR expert.

If it helps anyway, good luck!

Matt.
