Focus - water ingress - jmc
A pool of water accumulates in the passenger footwell of my 2002 Focus TDCI when the vehicle has been standing duuring heavy rain.
This started about 6 months ago and persists despite investigations by the dealer. They seem however to think that the pollen filter housing is to blame but they have resealed it several times....
Originally I thought water was coming from the heater outlet below the passenger dashboard but now I think it is coming more from the centre (steering column area). Has anyone else had this problem?

Several threads mentioning problems with the pollen filter causing the ingress.

I've found a couple that might help.
