I have a 2012 Range Rover Vogue 4.4 TDV8 and when it rains water was pouring down from the top of the windscreen all over the touchscreen and dashboard, not ideal. It also soaked the front of the headlining.

I thought it was the sunroof, checked and cleared drains and it still happened. I then removed the top console with the sunroof switch (two screws up under the sunglasses holder) and I could see the water was coming in from the join of the windscreen.

I lifted up the rubber at the end of the roof channel where it meets with the top corner of the windscreen and found the drain there was blocked. I blasted this with a hose and it cleared and the water has stopped coming in. I guess I have a slight leak in the windscreen seal but it was only leaking as the water had no where else to go. I pushed some sealant gunk up between the windscreen glass and metal where the leak was dripping so hopefully it wont happen again.

Hope this helps someone else with similar problems!
