Hi,
Good Post, but of course it's only relevant to the '97-'02 Models. These Cars have the 1st Gen VarioCam which uses a simple Solenoid Mechanism controlled by the DME. In it, the Valve Timing is in either the Standard or Advanced Mode, a simple ON/OFF.
The 2nd Gen VarioCam used in Models since '03 uses an Oil-Filled Stator with internal Vanes. The Hydraulic pressure created by the turning Vanes causes the Cams (and the Valve Timing) to shift infinitely through it's 40° Range. It does not use Solenoids, or the DME, to activate it. Hope this helps...
Happy Motoring!... Jim'99
