The problem with trying to describe sounds over the interwebs, is just like trying to describe shades of a colour, even uses slightly different terms. If you're in doubt, visit your dealer. The sound very well could be the climate control as you've described it, but it could be something else...

Your understanding of the supercharger is not correct.
To quote VAG's self study guide. "From a minimum torque requirement and up to an engine speed of 2,400 rpm, the supercharger is constantly activated." Above that and up to 3,500rpm, it's activated as required. So in other words, it does just "jump in". But again, descriptive words can vary from person to person.

Actually based on what I've seen on VCDS if you're cruising along at under 2400 revs on the freeway with light throttle, the supercharger does end up disengaging. On my vehicle you can hear the faint 'chirp' sound when the clutch for the compressor enages if you prod the accelerator. I have to be driving with radio off on a smooth road to hear it.
