The guy in the video can access that info only because the control module lets him. He was working on a newer car platform and it is dependent what is written in the firmware, so it's not a feature missing from your VCDS. The software / firmware in the D3 is generations old now.
Ok, thanks Matty, I think I've got that.

But what will changing the wheel circumference in the Nav module actually do?

I've put my new(17"), and old (20"), tyre details into this calculator:

That was inches. This one is mm:

So, I put in 2167.........yes/no?

And thanks for explaining the Youtube VCDS stuff

EDIT: Sorry, can't get the links to work properly. Just click on the inches and mm to compare.
