I have found undocumented leaking place. No more leaking in footwels.
I changed windshield seal, seal between glass frame and firewall, seal under roof, ac to firewall seal and it was steel leaking.
Finally i found two leaking points, each on one side of the window frame, where alu frame sides are welded to the lower straight part, there on connection in the rain gutter there is some micro movement happening and there is where water enters and flows along firewall behind the dash and fill the footwels. Just applied some Sika 221, and for 7 months (and during harsh wint) there is no leaking. Def is finally dry
If you cannot solve your leaks, you can look at this place, maybe you have the same problem.
Wish you all dry cars
