2021 M340i Missing Auto Start Stop Off Function
Just took US delivery of my M340i and notice that the auto stop/start "off" button is...not there anymore. Coming from a 2017 F30, I was prepared to have to disable the ASS each time I got in the car, but now it appears that button is entirely missing.
In sport mode, it still deactivates ASS. I am wondering if I can use bimmercode to also disable it in comfort mode, even though the physical button is missing. Anyone else have experience with this in a '21? UPDATE : Confirmed this is standard for 2021 M 340 models. Followed another users suggestion to configure Individual Sport mode with all comfort settings. This is the setting I use when I know I am going to be in stop & go traffic on my commutes.

Is there a noticeable engine turn on / turn off like typical auto start stop? |

All new G20 after July production came with 48V mild hybrid system and BMW removed the ASS feature.

Had a question, with that new 48V system do you feel that the moments when the engine turns itself on after idling are less jarring? Is the auto start / stop function overall less of a nuisance?

I have the same car with the same "problem". I've coded to always start in sport individual, then I configured sport individual to be "comfort" on all items. It has solved the problem for good here.
That said, the stop/start thing on the mild hybrid is much better than in my previous 2018 540i. Also that said, I still hate it. :-D

I use the app Bimmercode on my Android phone, with this adapter:
https://www.amazon.com/ScanTool-OBDL...dp/B00H9S71LW/ It's quite simple and dumb proof. I've also changed my cluster and HUD to the M version, which is much nicer.

I have had my 2021 for almost one month now. If the car is in sport mode the engine does not shut off.
I will say i do not notice it when it shuts off especially now that it's cooled down outside. The AC slowing down on a hot day was annoying. Other than the AC I have not noticed. |

Keeping auxiliary things going is a nice bonus, but also not the main advantage of the mild hybrid system. The starter generator is the big advantage of the 48V system. It can provide additional torque while accelerating, it turns the engine on faster and more seamlessly/more comfortable and mainly it allows the engine to turn off while moving (coasting). If anyone wants to have some more in depth information on that topic, it was discussed in this thread already. Last edited by Flamingi; 09-22-2020 at 04:28 PM.. |
