There's at least two 'hidden' menus!
The 'Red Manu' is the information and management of the MMI bus that manages the media ECUs - this is 'Setup and Return' for about 5 seconds. This works on all MMI systems.
The 'Green Menu' is the 'management of the car' menu that's mostly, if not all, in German - this is 'Setup and Car' for about 5 seconds. This only works if the appropriate setting has been preset in the Control Head. If not set, needs something like VCDS to adapt the value.
