Hello all, I've got a very annoying problem with my Lupo 1.0, the interior gets very wet and soggy starting from the passenger rear foot well after heavy rain (the car is parked) I've tried all the usuall quick fixes of unblocking the scuttle panel drain and checking the joint in the washer jet pipe and all fine, I'm going to check the door panel membrane but i can't really visulise how it gets in through the door card membrane! Any help or advice very much appreciated!
