I had exactly the same problem, but only the drivers side of my van, finally up to an inch of water when I took the seat and carpet out. The fault was a pencil sized hole behind the black plastic wheel liner. Jack up the car or van, remove the wheel and liner (held on with plastic plugs) and right in the corner where the inner wing and firewall meet about 3" below the drivers side wiper area drain hole there is a line of weld and mastic. On 2 vehicles (mine and a neighbours) Citreon have failed to fill the hole with mastic. Normally this does not matter as the drained water travels on down behind the wheel liner and out but over time debris collects behind the liner, stops the water flowing out and it finds it way through the hole. You can,t see it from inside because of the upper carpet behind the throttle pedal. You need to remove seat and carpet even when you,ve filled hole because the carpet foam retains the water unless you hang it up for a week. To save removing both seats and full carpet, unscrew central gearstick and hand brake plastics just enough to be able to cut carpet with a stanley knife under the plastics (TAKE CARE NOT TO CUT WIRING). I,ve never had a problem since filling this hole! Citreon.......TAKE NOTE.
