Noticed for awhile tailgate didn't unlock on the fob .it used to. Then now and again I'd go to open tailgate and it wasn't having it. I'd have to  lock and unlock couple of times. This only happened now and again . We'll today it wasn't opening at all .so popped it from inside to check it out. Lock was replaced 3 years ago. And there power to that  but the microswitch release switch handle doesn't do enything, no wire damaged that I can see and there isn't eny power to the switch ? Or is the switch just foopard

If you look on the SEATCUPRA forum, there has been a few people finding that there is cable connection, ie plug pin>socket pin, within the rear hatch, that can get wet and so end up with a "bad" connection, I'd think that Fabia and Polo will be roughly the same in this area.

 

Failing that, there is always the possibility that a cable has ended up shearing on the cable run between the car body and the hatch - ie in the area that is covered by a flexible rubber sleeve.

Couldn't see a join or socket in tailgate but I've had problems sorted in area just into the roof from the bellows area affecting rear wiper so wire break possible as I've also just sorted passenger window as partial wire break in bellows on door
