Embarassingly avoiding the last 2 messages on performance cars, I've had a couple of weeks using Autohold on my 1.0 DSG, after 2 previous years as an ignorant Autolhold sceptic. I'm now leaving it on most of the time - agree with Kenny R it's great with the DSG and does make starting from standstill easier on the right foot and it's generally a bit less effort to achieve a smooth take off. I've tried some moderately fast getaways turning right from a side road into a busy main road and no wheel spin or tramping so far, but too early to say for sure. I've still to try really putting my foot down while in Sport from standstill. If not for the rather-oversensitive-to-small-movement-at-top-of-throttle-pedal, it would be as good as my torquey old Saab 9-5 2 litre auto & is already nicer here than my previous Yeti 1.2 DSG (and as it happens my older BMW E39 523i auto too - always seemed a bit sluggish in spite of the good 0-60 times, unless I really used the throttle).
What I didn't like on first getting the Karoq & before I was used to it, was using Autohold with Stop/start. Initially pressing go, the engine would start with a slight jolt + taking off in Autohold I tended to do too suddenly. That put me off using both facilities for far too long, but that was before I learned the trick of twitching the steering wheel - anticipating moving off a few seconds later. Still only use Stop/start occasionally, when a longish wait expected, replacement EFB batteries aren't cheap.
Going back to a point made by RootToot, stopped in traffic today, I did notice from the red reflections in a white Transit behind me, that the rear brakes lights are illuminated when Autohold operates - need to think more about that, but reluctant to give up Autohold now.
