FR ST 2.0 diesel - which DSG does it have?

[Resourcerer]

Hi All - may be answered before but I can't find it. I have a 2018 FR ST Technology. My spec label shows CUNA which I think is the engine code (2.0 184 PS diesel) but no gearbox code next to it. Just bought the car and not sure what gearbox servicing it should be on. Any advice?
Thanks in advance

You can DM me a VIN so I could check that

Here is a gearbox version: SYW (0D9A DQ250-6F)
