Welcome to the forum you'll find the members on here are a friendly and helpful bunch 🙂 looks a lovely car. And Scotland is beautiful. I did the nc500 4 years ago and loved it. Sorry to hear you've had problems.
Has it got a private plate? Or has it been imported from Japan or elsewhere?
Private plates don't show up properly on tfl. I'm 95% certain it won't be compliant.
To prove it you'll have to contact VW for a certificate of conformity.
Has the car got cruise control? Or were you hoping the stalk would give you cruise control? I ask because if it's the latter then it'll.nerd to be coded to the car to make it work.
If the ccm is corroded, you might be able to clean the wiring but ultimately it'll need replacing with a part with an identical part number. It usually corrodes as water getting into the cabin.
