I can see what it is through the VIN inspection plate
You missed one important adjective: 'wet'
It's not drying. This either means
1) Because it's coolant it's just not going to dry out at all.
2) It's just not going to dry out in this weather. (Interesting to note the boot deadening dries quite rapidly)
3) There's still some kind of leak of something from somewhere into the footwell.
I think it's 1 or 2. There's no loss of coolant and the checks I've done by peeling back the carpet at the top of the pedals and looking at the metal indicate no evidence at all of obvious liquid ingress. However, the car still mists up like a sod (I accept a portion of this may be coming from the boot leaks), and poking the sound deadening under the VIN hatch reveals it to be pretty manky with *something*. So, plan of action this weekend (if I can get time)
1) Hope the temp is high enough to get the antenna / conduit / seam sealed in the boot.
2) Get the foot well carpet lifted
3) Get the deadening out, and see if anything obvious presents itself. Get it to dry in the garage.
4) Temporarily replace deadening with newspaper / cardboard and check regularly. This should show me if there is anything leaking, and if so from where.
5) Fix any leaks next week.
Simples!
Anyone see any flaws at this point?
