I have the same problem. drenched carpet in foot well storage.
Wiped it up 4 times but it just keeps getting drenched.
Also, after heavy rain there is water swooshing around when i make left or right turns.lol
sounds like it's coming from the dash board.
I'm baffled how it's getting in.
I'm guessing it through the air intake just in front of the windscreen.
