Wet front passenger footwell
Hi All, It looks as though I have a leak in my sun roof drain . Footwell soaking wet and there is puckering in the trim of the A frame pillar. Is there a guide on how to repair this please?Belts, oil pump casing and water pump by Flack

Yep!- do a seach more than likely drain blocked.It can when others can't,
It will when others won't,
It goes where others don't.

Usually its the end of the hose (part no EEH500120) which deteriorates through time.
Cut at the end and use a Plastic Barbed Connector Pipe Tubing Fitting Air Fuel Water Vacuum
smth like the below one

I too had this issue. If your lucky, it’s just a blocked hose and the water is over flowing the gutter and running down the a pillar but more than likely the end of the hose has perished and water is draining into the footwell. I did this and the pain is removing/refitting the mass of electrical connectors at the CJB or somthing like that. If I’m honest it’s a job I hope to never do again as there was a point that I didn’t believe it was humanly possible to re attach all the connectors. My hands are not the largest and looked like I had been feeding a lion when I eventually succeeded. There is a clever trick to remove the glove box that involves a bolt and a plastic sleeve to get the pins out. There could be an alternative way of doing this by threading it from the wheel arch side but access is not great in there either from what I read at the time. Drivers side is
probably a 10min job but it’s never that side for some reason unless you have a left hand drive.

Two useful points here - from one who suffered BADLY from this hassle :-
DRAIN YOUR FOOTWELL ASAP
I found, through failure over time of both handbrake winch supply and central locking power feeds, that prolonged presence of water in the passenger footwell is BAD NEWS - in the case of the handbrake power supply electrolytic corrosion had crept backwards along the strands of the green wire, "rotting" the copper. I suspect a similar process inhibited my central locking until I applied the now-famous three-wire re-splice.
So, although it's against instincts, I tilted my car with OS wheels on a kerb and drilled couple of 3mm holes in my wet floorpan, beneath the BIG bunch of loomed wires just inboard of the rocker plate. These can later be filled or plugged so you can still ford in future. That and a fan heater over a few nights dried things out. Getting the carpet and soundproof foam up is a considerable hassle ((
Because there's SO MUCH floor insulation between carpets and floorpan, it's very difficult to dry-out this part of the car after a soaking. Having wiring in the same place, esp. with splices/joints creates a recipe for electrical trouble.
RE-ROUTING THE FNS SUNROOF DRAIN HOSE
I couldn't fiddle to replace the FNS hose lower elbows feeding out into the wheel arches, and I viewed removing the fusebox as taking too damned long. So I exposed the existing downpipe behind the A-pillar trim, cut it and bought very thin-wall flexible plastic hose to push OVER the existing downpipe, creating a new extension; pushed the new hose upwards over the old for 2+ inches to reduce chances of future overlow; perhaps should have sealed that joint.
I was able to "fish" the new plastic hose extension down behind the fuse box and into the footwell. I drilled the footwell floor (WATCH this, don't drill any deeper than break-through into the footwell sheet), fitted a plastic hose elbow into the hole, onto which I coupled the new extended downpipe. I lined the hole with a rubber grommet before pushing-in the elbow. So the FNS sunroof drain now exits through the passenger foootwell floor. Applied silicone sealant.
I cut-away a channel through the bulky foam insulation which sits on the footwell floor, the foam and carpet sat down again with no sign whatever of the new drain hose.
The hose extension behing the fuse box down into the footwell had to be squeezed through and this constrained the diameter somewhat, but when I tested the drain (ROS wheel up on a kerb) it worked well enough and water pooled beneath the car under the floorpan.
COMMENT
Personally I'm convinced (after owning 3 x D3s and a D4) that SO MANY apparently complex electrical failures with these cars are due to water in the footwells. The resulting diagnostics are bizarre and haywire. SO MANY costly breakdowns and workshop visits suffered by owners everywhere, all due to the numpty who allowed those defective rot-prone drain hose elbows to be fitted. All that fine engineering brought down by bits of inadequate rubber.

we drilled holes in the footwell. Even though we have fixed all the leaks above the floor you never know when it might pop its ugly head.
As mentioned water collecting down there is a huge problem for electronics. with the hole the water never collects. It drains directly to the ground. Just be careful drilling on the side your air reservoir is.

We never use our sunroof. It is permanently closed. Therefore, can a blocked drain cause a wet footwell.Discovery 4 3.0 HSE Lux, 2015

The answer is a BIG YES !!
Glass panel is never a watertight fit in the roof aperture, which is the MAIN reason the drain gutter exists !
You have to apply a waterproof seal around the glass before the drain gutter becomes redundant.

Thank you. I will seal up the roof to try and eliminate that as a source. The water is on the driver side where the drivers feet sit. Passenger side is fine. I will also check the aircon condensate drain.Discovery 4 3.0 HSE Lux, 2015

more than likely drain blocked.
