At wits end with this now, I can't see any water tracking down from behind dash, window seals look good, sunroof looks good. Seems to get very wet in the footwell when driving, had carpets up and no holes in floorpan, anybody have any ideas why it's getting so wet? No loss of antifreeze either, really don't know where it could be coming from

It seems to be right where your heels would sit, the whole carpet isn't wet, just where my feet are and same for the back, but it's sopping wet and it's not coming from wet shoes.....Are there any common places MK3's leak? iIve heard bulkhead will bring water down behind the dash, but up by the pedals it's bone dry so can't be from up there? Any ideas?
