I am thinking of buying a VAG-COM cable for my Audi A8L 2013, D4 3.0 Quattro. On your support page http://wiki.ross-tech.com/wiki/index...rocedures#Audi my model, Audi A8/S8 (4H) 2010+, is listed but is greyed out and not selectable. Can you advise what this means please is the tool fully functional for my model.

Many thanks in advance,
