If you had an lci, it's coded into the car to remember the last setting anyway, no need to actively code it (I was like wtf why is my cars stop start off? I was expecting to have to turn it off but then it just stayed off after the first time I did it.) Coding on the car still says start stop memory is off so it's stored somewhere else than say on the pre lci or f10 models maybe the dme?

And 100% the feature won't work if the engine and fluids are still warming up, had the same thing in the AMG, where it stated in the manual, pretty sure it states that in the BMW manual. In the AMG thought you could not override it if the engine was cold, it just wouldn't work, it think the BMW if you cycle the button it might activate even on a cold engine. Will have to test that. I'm not worried about engine reliability, its a myth since the stop/start vehicles come with more robust ignition components. But it seems that the function does not turn on for me until I get to do multiple consecutive drives, my first drive to work is about 14 miles and it never turns on which is nice. |

Until fluids warm up is a very broad term, are we talking coolant temp with dead cold oil? Fully warmed up oil? Halfway warmed up coolant? Lots of different scenarios, and I can't really say for myself since I never use it. But in a rental jaguar xf with the supercharged v6? It would turn off at the end of my street which us about 100 feet. We can agree to disagree on that, it's not the ignition components that are the issue, heck even the starter might be fine, the main issue is the wear and tear between metal parts of the engine that don't have an oil film to separate them (and youre gonna say everything is coated in oil so its fine, and yes while it's less wear than a cold start, you still need a split second to get oil pressure to push the rods and crank away from the bearings they rest on when the engine is off) as well as potentially the top end where the oil has drained down if left off long enough (and it doesn't take that long) but hey I'm not gonna tell you how to drive your car. Just gonna put this in as a closing remark: when I went to do my performance delivery, first thing they asked us to do was turn stop start off for the track vehicles since "you're gonna be stopping a lot and there's no reason to put so much wear and tear on these cars" and even when we were in the m340 doing the skid pad, were told to just leave em on since it's better to idle than to turn em off and back on again. |

That said, I don't like the auto off feature and my 2019 M5C does not permanently remember if I turn it off and neither can it be coded to stay off. Sort of a pet peeve, really.

And it's not that I'm suspecting, I'm well aware how engines work, and from what it seems like you do too, so you know that it's the oil pressure that really maintains that clearance at which point you achieve hydrodynamic lubrication instead of boundary lubrication during startup and shutdown. And you are correct it doesn't add significant wear to someone that doesn't plan to keep the car which is why I'm not really getting into it lol, the cars are designed to last say 60k miles for the average user and that's about it, around 100k you start getting your major failures (seals, hoses, pumps) and I'd say around 150k it's time for bearings and such assuming proper maintenance was done. (Significantly less if you're using the start stop imo) |

I have a 2020 pre-LCI.
My car remembers the previous setting when you shut down. I turned off Start/Stop on day 1 and it has not turned on since then. |

As others have stated, LCI will remember the last start/stop setting in the default startup mode. If you're using M1 or M2, you'll need to ensure that you select your desired start/stop behavior in the M mode configuration.

I haven't looked into coding the on/off feature in a long time, I'm definitely going to revisit. Thank you.

I don’t understand what the deal is with all the references to LCI and coding, neither are needed for start/stop to stay off. I bought a non-LCI comp as soon it was out, hit the button once and never dealt with it again.
