So need to do mine again. Sure they must be slipping, think I defo need new ones. And for £10 can't hurt to try lol.
Sorry mate did u manage to source a prat number?
Yup, it's 1J0 711 761 B it's listed as 'Catch' and is £8.24inc vat 
Awesome cheers mate. Did u fit it yourself?
Yeah, took 2mins to fit & another 2 to realign the linkage....absolute doddle

To fit:
1. To remove the old one you need to loosen the clip by compressing the spring and twisting clockwise - it will lock into place and the 3 arms will release from the rod.
2. There is a little round silver clip that goes over the top of the bush, this slides off and the whole item just lifts out.
3. Compress the spring on the new one, place into position & put the silver clip back on.
