Best way to test it is sit in the car and run ahose pipe over the doors
that side or use a watering can.

Thanks for the suggestion Chris.
I tried soaking it with hose but i couldn’t spot any leaks.
I think the leak is coming from underneath cos it is only the floor
that is wet and not the carpets which are up the sides.
Any more ideas?

I have the same problem with my daughters 96 pug 106, apart from a
tiny leak from the roof ariel (fix with leak n seal), if you remove
the plastic from the base of the windscreen you will find a small
rubber grommet between the plastic water deflector and the wiper
spindle, replace it (at least the drivers side one) because the ruddy
blower air intake resides RIGHT UNDERNEATH THE DRIVERS WIPER SPINDLE,
so any water dribbles past falls straight in to the blower as its only
covered with a crude plastic mesh to trap leaves, goes straight into
the orofice and then down the accelerator peddle and into the foot
well and that my friend is a really bad design fault!!
A piece of plastic or lino curved over the airwell and apoxyed into
place should stop this happening again.
The actually spindle is fitted to a bracket above the inner scuttle
and smack bang over said airwell , ps if the other guy with the leak
from the back end is reading this she had water ingress from the
offside light where the rubber seal had aged and distorted, a thick
smear of petroleum jelly does the trick here or wet the rubber with
leak n seal to make it stick to the metalwork behind the lamp. :

Then you need to take off drivers side and rear door trims to first check the
door membrane if this is holed then bingo you may well have found the problem.
