Water leak in to the front passenger footwell

(1/1)

Hi, i have a water leak in to the front passenger footwell (LHD car, so right side), what i tried:
- reseat the scuttle under the windscreen
- clean the whole tray under the windscreen
- remove, inspect and put back all the plugs and the plastic mesh for the blower motor in the tray with silicone grease around them
- Checked the 2 drain hole in the tray



After a rainy night, there was water in the hole with the red circle, and i think the water is leaking trough between the two metal sheet in the end.
I put paper towels everywhere and in every hole, everything else above was bone dry (door seals, where the door cables comes in, blower motor, cabin filter, etc.)
The black sikaflex was me, because first i tought thats where the water leaks in, but i was wrong.

I tried to pour water everywhere, above windscreen, under windscreen, front right door, like everywhere but when i did everything stayed dry, no water came in.
The leak also happened when the car was in one place so i dont think it comes from under the car.

What else can i try?

Edit:
The car doesn't have sunroof.

I have this issue too. But never found the cause. I gave up searching to be honest. The metal is quite well protected so I wasn't so concerned with it rusting through a sit does dry up quick. I use a car cover if it snot being used for a while too.

Little update, on an another forum a member had the same issue and he managed to fix it by sealing a square hole in the wheel arch.



I also sealed it, but sadly it didn't fixed my problem.
