I would assume the BMW factory diagnostic computer does the same. I'm not familiar with any other systems but would assume they function in a similar fashion as well.
So no the EFI computer doesn't automatically re-engage the steppers all on its own, at least during these diagnostic functions.
Thanks JJ. Kinda what I figured. Haven't really used the 911 too much yet. Just cleared a fault code and re-set my service interval for another year (glad to not have to rely on the stealer for that anymore!)
