I didn't buy a new carpet.
I washed the offending smelly areas.
While wet toward damp i powdered it with some soda bicarbonate,
heard it helps neutralizing smells, and then had it dry,
Plan to fit the same carpet.
Meanwhile, as i am concluding whether the firewall pad dampness is
from its drying or leakage ftom the A/C, i drive my car
with some homemade rugs and pads on the floor.
Center console removed, looks wild.

Igor
