what did you and your mk3 leon do today

looks the same to me with 5Q0 steering column control unit

That's good news. It would suggest that only VC is required to have information about activation/deactivation of heated steering wheel.

why did you expand the VC?

You mean why I am removing VC for installation? I am routing positive wire to the fusebox and ground wire to the ground point behind VC. Take this image with a grain of salt, it only shows approximate location of wires - red for positive, blue for ground. I don't know what is the best solution for RHD vehicles, but for LHD this method works fine.

yes, correct, I have to be a little more careful when translating. I have the ground connected to the ground point behind the hood release at the end of the A pillar. Of course I have a left-hand drive car

Can you ask what hardware and software his VC has?
