Dealers guided VAS system doesn't let the dealer do much now has it is all done by internet connection to germany...So dealer doesn't see the SKC code or transfer of mileage
All they do it plug it in press a button and it connects the data is taken off then the cluster is swapped and the data re-booted back onto the new cluster with every thing that should be there,
I watched them do my original cluster when it got damaged accidentally on purpose
thank goodness for warranties.
