Hi there,
If you search my threads I did quite a comprehensive one on the wet footwell.
In addition to the CEM leak and others mentioned you can get a leak from shrunken sealant on the inner wing that allows water to track into a box section behind the pedals and then leak into the footwell from a gap in the panels. (Easily fixed by spraying the offending area of the inner wing with waxoyle).
First thing is to get the front carpet out, get everything dry and see what you have.
If you make up a dummy footwell from expanded polystyrene wrapped in plastic you can use the car whilst it is drying out.
If not you risk treading on wiring and your feet not reaching the floor 😂.
Expect at least a week if it is very wet.
Rather than repeat everything here pm me if you can not find the thread or are struggling.
I am not far from you and can talk you through it.
Good luck.
