Furby VRS Boot Leaking

I noticed the other day a small stain on my seats just behind the middle seatbelt??

Was wondering where it had come from so sprayed water on the car and sat in it to see if there was any leak....nothing.

Then this morning as I got my stuff out for work there was a "drip drip!" onto the seat :confused: It could just be the water running off the boot onto the roof and some into the boot but even then surely Skoda must have thought about this and my Elegence model never did it. Anyway I will question my local service dept tomorrow ( have to pick up replacement plates as the lettering is fading, 2nd set in 2 weeks ) has anyone experienced this or have any ideas incase they fob me off.

Cheers
