I searched and found a similar problem in the B8 section, but with no solution...
I've noticed over the past couple of weeks (since my service actually, however I think that's coincidence), that when I first drive the car, i.e. leaving work or leaving home and I set the cruise to bang-on 30mph, the revs fluctuate between 1450ish to 1350ish rpm.
This only happens as EXACTLY 30mph, 1mph over and it's fine and doesn't hunt. Also it only does it when the engine is cold. Any ideas if this is a problem or just 'one of those things', which is pretty minor, that will happen unless the engine is warm?
Scanned the car, no (related) fault codes found
