Looks like the fabia wiper conversion, think its about £20 from the dealer for the parts

Skoda Fabia Estate Wiper Arm pt number 6Y6955704 (maybe replaced by 6Y6955707A)
Fabia Estate Wiper Blade pt number 6Y0955425
Fabia Hatchback Wiper Cover pt number 6Y6955435

If you speak to Chris285 i know he has one and maybe able to get the latest pt number off his wiper arm
You can also fit a Touran rear wiper and arm
