Skoda Superb MK2 2015 saloon bootlid not working

Hi all,

My father owns a 2015 Superb MK2 facelift with the dual bootlid. A couple months ago he found a lot of water in the boot, and ever since the tailgate won't open. The switch on the right hand side for the dual lid works, but the center switch doesn't do anything.

Our mechanic reckons it's the lower tailgate actuator. I'm just having some trouble finding a replacement online, if anyone could supply a part number I'd really appreciate it.

Any advice is also appreciated.

Thanks all.
