New Audi owner struggling with My Audi set up

[Hammer]

Hey guys, I'm Phill from Birmingham. I just got my first Audi - a 2017 A6 Avant and I love it! I tried to register on the app but it keeps rejecting the VIN. Does anyone have any ideas on what I may be doing wrong? It's driving me mad.

Thanks All.

Have you tried checking the vin with DVLA just to make sure it is correct
