2 Door, Wet Carpet. Any one else had the same?

Seems we have a leak and are getting wet carpet in the drivers footwell.
I know the Fabia Mk1 suffered from dodgy rear door seals.
Does the Citigo have the same problem, I wonder?

This only occurs after heavy rain, and I've just discovered jet washing causes it as well.
It's just out of warranty, by 2 months, and Skoda want £70 just to look at it, cheeky buggers!
