Found the leak!
Hi all

Have had a lot of time on the defender this weekend and got to the bottom of a leak that has been filling my passenger footwell for some time now. I've found where the dripping is coming from but can anyone advise whats the best way to tackle this one? It seems to be coming in from behind this black metal plate under the dash-

You've only found where its dripping from the dash. Thats angle is there to hold the foot well liner.
Now you have find where it's coming in.
Common culprits are windscreen seal, windscreen frame to bulkhead seal, around windscreen blocks, door seals, windscreen frame to roof seal.
Happy hunting

It is either your windscreen seal or windscreen frame to bulkhead seal, or possibly your bulkhead vents not sealing.

I had a leak when it rained in the same place. Both sides. I replaced the bulkhead vent seals and the leak stopped. I'm crossing my fingers that was it. Take your time and place them in carefully to the outside edges. That's where the contact is made with the rim.
One thing I also did was lube all the pivot points of the mechanism which operates the vents. It was pretty stiff. You need all the help you can get from it to pull the vents closed tight. I watched a video on replacing them. One thing I didn't notice initially was that the mechanism is connected to the vent closer to one end - not in the middle. So it doesn't spread the closing force equally across the entire vent. So helps to have a smoothly operating mechanism.
Good luck!

Mine were actually pretty easy to get out. Once out I cleaned them up really well though.

The two nut type on the late TD5s are a nightmare. The last one I had I had to cut the nuts off one end carefully with cutting disc on grinder, the use punch to knock them through the bulkhead hinges. Even then two were seized absolutely solid and required heat and then localised respraying of bulkhead.

The Genuine Land Rover vent seals are useless. They don’t fit properly to the vents, the foam is too thin to form a correct seals and the glue fails in hot weather, Amazingly Britpart vent seals are far superior!!!

Oldowner - I completely agree! I have managed to get the nuts off but the pin is absolutely seized. Have tried nose pliers to move them and a hammer with various things but it’s in such a hard area not to damage anything else- will try the punch technique but fear I may too need some heat which will make a right mess! Keswick green 2007 Defender 90 TD5

I unbolted the flap underneath then with a pair of vice grips on the hinge pin and liberal amounts of wd40 repeatedly sprayed at the pin from every side, I spent about half an hour lifting the flap up and down to almost vertical while holding the pin still with the grips. After a while they freed up so a few more douses in wd and I could wiggle them free. Ray
