Anyone know how the two-stage variable intake manifold works in detail?

At what RPM or what throttle position this is activated? Can this be watched with Vag-com?

I can't find any info on how it works.

You might consider joining the Audi Club. In the quattro quarterly a couple of issues ago

they did a good tech article on it.

IIRC, it switches at 3k RPM, independent of throttle position.

Somebody correct me if I'm mistaken.
