I doubt that a HU swap will be required, the ACC has been available since 2003 and should be in the SW already. HU swaps have only been required for crs requiring video so a new HU with Fbas is needed.

The can gateway controller has to be swapped on cars prior to 2006 that require camera.
 
No you should not have to, easy way to check is use VAG COM and see if it is an option in the installation list.
 
Dale, did you manage your ACC upgrade then, did you get a new cluster?
 
I do not think your Can gateway supports ACC, my can gateway which specifically complains about ACC because it is not connected and I cannot disable it at all means it is an ACC gateway. Maybe your problems stem from the wrong gateway.
