Auto start stop is inconsistent?
So sometimes engine auto start stop works fine i.e. as it should, come to a stop and engine goes off until clutch is next depressed and it is restarted.
However this is only about 25-30% of the time and I can't work out why. I know th engine has to be a bit warm before auto start stop works and am having the issue even when the engine is fully warm. On the cluster display it often has autostart/stop symbol crossed out. The ONLY thing I can think of is it does this more since having the ghost immobiliser fitted? Any ideas? |

Also depends on engine temp, time since last start/stop event, clutch position, duration of last start/stop event etc. When the conditions for start/stop have not been met you will see a crossed out symbol on the dash.

Who runs auto start/stop anyway? I plan on keeping my M2 a long time and don’t want the wear from auto start/stop.

Since I normally drive in Manual mode, it never bothers me. I do however use the feature by choice when I know the red light phase is long. So it does get used, just rarely. |

I turned the feature off with the touch of a button, but I'm in the US. |

These things can cause it to not shut off the engine.

I actually use the feature to give me an indication of the status of the engine / battery. I know if I go out of town for a week, Auto Start-Stop will not activate again for about another week of commuting.
If you have something pulling power from the battery when the car is off, such as a dash cam or similar, you'll almost never see Auto Start-Stop activate.

It did start stop flawlessly today. My commute however is extremely short 10min in traffic 5-6mins in no traffic. I basically get to work and engine has just got up to 'OK' temp but not fully warmed up.
I agree it makes me think the engine and associated parts will wear more quickly with minimal fuel savings, if I ever get the car coded might be tempted to code it off. Just wondered why it was inconsistent. |

Use Bimmercode, or E-SYS to code it out completely

is...annoying. Turn it off. You don't need bimmercode to turn it off completely. If you just hit the button it won't come back on until you re-hit it (which i have done a couple times by accident tbf)

Only in the US; European models switch on again every time you start the car.
