This may just be me being picky but I have noticed that the stop start system sometimes just does it's own thing. I have had it on quite a lot and have noticed on a few occasions that when I come to a stop (foot off brake with auto hold on) the engine just keeps running. 

 

Any ideas?

Many many things can cause it to stop/start and the Car button on your infotainment system should give a clue. Sometimes it's the generic 'power consumption too high' which can be anything.

Things that can affect it include:

Battery condition

Windscreen misting up

Aircon settings

Steering angle (full lock)

Steep hills

Phase of the moon

Distressing colour nearby

Just disconnect the sensor on the negative rail of the starter battery, by by stop/start hello fully charged trouble free battery.
