As the title says.. I had a wet spot under the front plug on the drivers sill. I cannot remember why it does that, could someone remind me please. When I pulled the plug out there was a enough water to fill a coffee mug. ?
There shouldn't be that much water in the sill... The other side which is dry is how it should be.
I dunno where all the drains are on your car (e.g. whether you have a sun-roof or not) but a few cars have drain "pipes" which come out inside the wheel arch, behind the liner.. so the water can run down the liner and out through the bottom.
I dunno if something is blocked, or deranged and the water is running the wrong way (e.g. down the wheel arch itself) and getting into the sill. If it was mine, I'd get the beast onto a ramp to have a good nose around.
