On my 2015 535i, you were allowed to turn off auto shut off when stopped at a traffic light but it seems like there's no way to permanently turn if off this time. You have to toggle it off EACH AND EVERYTIME you get in the car. It's really irritating that the car keeps turning off when i come to a complete stop. I feel like it ruins the engine. Not sure why BMW doesn't let us turn if off for good.
