I'm starting to get a similar sounding problem as the rough take off - mine is DSG though.
Never noticed it until a few weeks ago and I mentioned it at my 15k service.. they have reset the DSG (from what I was told) but it seems to still do it.
Sort of shuddering - a feeling like the car is trying to take off without having the revs up and is going to stall, followed by no power and then finally it takes off. Its not a constent thing though, over the past 10 days would say it has happened twice.

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.
