On the road right now, but theres single vanos and dual vanos. And its very different than hondar VTEC. Its based on advance, not on "dual cam profiles". Your car has single vanos (on one cam, the intake), S54s had dual vanos (both cams). If I get some time tonight when I get to VIR ill write out what it does, but it simply adjusts the cam timing based on load (a combination of throttle position, revs, gear).
Why you need to rebuild it is mostly the seals (bmw rubber/plastic goes brittle), or you can get a build for it to make the gears more "efficient" (less drag), but thats almost useless.
