Does this have a part number or does it come as part of the entire boot release mechanism? Mines split and I think if water starts getting in the whole button assembly will probably be kaput.

 

Cheers guys

Why not just use a bit of super glue to keep it water tight

.....and keep your fingers away from the glue until dry !!

£15 second hand from eBay

@DEL80Y nailed it, its part no. is 5E0 827 566.  It's shared with the Fabia, Roomster, Yeti, Rapid and Octavia

 

You can see the part in the online ETKA database - its #5 on the diagram and in the list here: https://skoda.7zap.com/en/cz/superb/sup/2014-768/8/827-827020/ 

Thanks all, I was hoping to be able to replace just the rubber bit but looks like the whole switch. Looks an easy and cheap fix though.
