I just purchased a beautiful 2024 BMW X6....much to my dismay it seems that Auto Start Stop cannot be disabled....

We all know the ASS button has been eliminated.

I tried setting all the Sport Individual settings to comfort...nope.

I tried driving in trailer mode.....nope.

I tried BimmerCode - they tell me their software is not yet compatible with my vehicle (but they are working on it).

BMW service tells me the only way to disable is to drive in Sport mode.

I've seen YouTube videos for other vehicles suggesting I disconnect the ASS cable from the battery....not sure about this idea and when I looked at the battery it wasn't readily apparent if this would work.

Can the ASS system be physically removed entirely?

So turning to the BMW Council of Wisdom and Elders - looking for any ideas....?

As a confirmed ASS hater I must say that after 1 week of driving my 2024 X6 M60i LCI that the improvement, ie: not that noticeable, has been a pleasant surprise. Not being able to disengage the system like I was able to on my 14 X5 4.4 and my 2020 X6 M50i was a big concern. Seems like when at full operating temperature the 48V Mild Hybrid has a positive effect in the annoying. department

It was worth getting the 45e just to not have to deal with ASS alone...

I thought the mild-hybridness of the 24's took care of that problem. At least for me the most annoying part is that the AC would blow hot air while the car is stopped. The 50e doesn't have that problem anymore.

I had a 2022 40i with 48v system and now a 2023 M50i without and there is very little difference between the ASS on them.

I am on a similar boat, have a 24 X5M and yes the ASS cannot be disabled while in Comfort mode in mine either. It is off in Sport/Sport+ mode and for me can be configured with the M1/M2 buttons. So technically if you want to drive with default settings, then configure those in one of the M buttons, but you'd still have to press it on every start.

A few years from now, there probably won't even be a start button, so I guess this is better than nothing?

There is no problem for the HVAC with the 45e/50e because it's not run by the engine.

Why does setting sport individual not work? I have a 2021 and I have it all set to comfort and just press it every time I turn on the car.

In sport individual - if the 'chassis' is set to comfort, ASS is on. This is a new 'feature' for 2024.

This was the unhelpful response from a BMW genius:

"Your BMW does not have the ability to manually deactivate the Auto Start/Stop feature, nor does it have the correlating button. The Auto Start/Stop function is default set to "ON" after each engine start using the Start/Stop button. There is no way to set this feature to default to "OFF" at start up. I regret any disappointment this may cause. Driving in Sport Mode, however, will deactivate the Auto Start/Stop function."


I'm wondering if ASS can be detached from the battery? Or physically removed from the vehicle by a mechanic?

No, it is part of the mild-hybrid system. Perhaps sometime in the future it will be able to be done by coding.

Doesn't the X5 M still have the button to disable it? What happens when you press that button in Comfort mode?

The X5M now has a mild-hybrid system so no button.

Looks like the button is there from 4:28 to 4:31

Sure does. I read that is was removed, perhaps they meant the functionality and in comfort mode it doesn't work as mencio stated. Hopefully he can chime in.

Yes the button is definitely there and can be activated once the car is started. But unlike all other BMWs I owned, the setting is not remembered on the next re-start, so it needs to be pushed (disabled) every time you start the car.

As I mentioned in another post, the manual states that this functionality can be disabled (permanently?) in the Chassis and Drivetrain settings in iDrive, but that is missing too.

So in short:
ASS Button: Can be pushed on/off when the car is on. Selection is cleared and default to off every time the car starts.
Sport/Sport+: ASS Off by default (can be enabled by pushing the ASS button).

Use the M1/M2 button to program desired ASS function as it is easier/quicker than finding that small button.

Final word: I cannot compare to pre-LCI, but on the X5M with the hybrid system, it is nowhere as annoying as it is in any previous cars I owned. The engine ASS is extremely smooth, and if it wasn't for the engine sound, almost imperceptible.

I have had ASS off in all my cars, and tend to drive with it until the car is warm then sometimes switch to sport. Doesn't bother me. YMMV.

So that's not really what the OP is talking about. You want a "set and forget" button that you only have to press once. At least you have a way to disable it.

In non-M cars, there is no button, and you can't disable it at all in Comfort D mode (the default). The only way to disable it on our cars is to switch to a Sport mode (eg, Sport/Sport Plus, or move from D to S on the drive selector). The problem with that is then the transmission holds gears much longer, so fuel economy tanks.

I can't speak for the OP personally, but I would gladly press the button every time I turned the car on. I mean I'm already pressing two buttons right there: one to turn the car on, and another to put the car in drive. What's one more click in the same general region? I've been doing that already with every other car I've owned that's had one of these systems.

And it's true, the auto stop/start is pretty good. On my car, sometimes I can't feel it, sometimes I can feel a very slight shimmer. But there are issues... like the AC will cut out when the engine turns off. And also, if you do a quick stop-then-reverse (like backing into a driveway), it will sometimes shut off and then you get a weird hitch. For the AC thing, Mercedes solved that with 450/53 series mild hybrids by getting rid of belt-driven accessories.

Even on the mild hybrids you can code it to stay completely off.
But since theres no button you have to code it when you want it back on.

The ASS is pretty good I will admit....but there is still a slight stutter at times and the vehicle struggles to maintain cabin temp at traffic lights. I'm sorry, but I don't find this acceptable for a vehicle of this caliber.

As for coding - I couldn't get it to connect with Bimmercode....and in correspondence with their software team I was told the '24 X6 is not compatible but they are 'working on it.'

I was going to code it this weekend. Bummer that Bimmercode does not support the LCI yet.

Coding on iD8 his very limited because it requires server verification, last I saw only a couple of ECUs could be coded.

[Dschlosser15]

To late now but if I knew this before I purchased my 2024 X5 I would have looked at a different manufacturer. Another fine stupid feature from BMW.

[1Mors]

I can code it out in my G05 with bimmercode. It's a mild hybrid too from what I understand. I don't have the button either
