Well, some updates from today.
First of all I'm eating humble pie because the dealer Master tech did indeed find the part number and the serial number matches that of the little white QC tag. (Location pictures attached).
The old part number is: 7LA8750597MH
The new part number is: 7LA875059C7MH
Looks like I'm going to get version 'C'. Whilst there may be some concerns if this is also watertight, I'm a bit more confident VW are taking it seriously by at least double-checking part numbers. So I hope they'll be all over it if version 'C' is problematical.

Today, I also had a call from VW Customer Care apologising for the troubles I've had with the Pop-top. Whilst Shahid is out of the office atm, the guy today said Shahid is now handling and co-ordinating my case. So another step in the right direction.
Pop top still not deploying properly so dealer has escalated that problem to VW too.
