Aah sneaky, didn't know if i'd get
for doing that.
Ok, well this is the leak. This is the best picture i have of it. Doesn't look like a lot unfortunately, think it had stopped a while and had started to dry up, but when its fresh it does literally flood the whole mat.
.
I'll put good money on the Door ancillary carrier, Mine went to the dealers, they sealed both ancillary carriers & when it rained , it leaked again, Not as bad, but still leaked. & when i took the door panel off, I could see why
The sealing of the carrier was slap dash to say the least, They just don't care about the job as much as you would doing it yourself.
When it is wet there, Undo the two torx screws in the bottom of the door panel & ease it away, See how much more water is behind there ... Then buy yourself a tube of black silicone, On a good dry day, Take the panel off & seal all around the edge of the door ancillary carrier, the re-assemble, I bet you that you have no more water troubles after that

Here is the Skoda version, they do exactly the same (P!$$ In) & i applied this to my Vrs & now to the Leon, Only diff, is the way you remove the panel, but to be honest, the Leons come off much easier
