Decided to tackle the problem today, so first of all decided to take out the passenger seat so I oculd gain better access under the carpet.
After lifting up the carpet I discovered i would be needing a bilge pump, ahoy there my sea dogs! aaarrrhhh
I must have taken half a litre of water from the footwell once I got the carpet shifted, and that doesn't include the water in the foam on the back of the carpet
Ended up taking out the whole carpet which was a bit of a fanny on, centre console out, kick panels off, glove box out, both seats, under steering column panel, throttle pedal
Now it looks a bit racer stylee, not driven it yet but that carpet weighed a tonne! Should be interesting.
Now with the seats back in, oh and some mats for that bit of luxury
And the cause of the water coming in????
Pulled the cover off and can see below the wiper motor that some silicon seal between the panels has had it, so plan to sort the seal out and prevent water getting in.
Can give the carpet a proper shampoo whilst it is out too.
Will keep you posted if this sorts it
not 
fook thats a scarey bill mate
