I wondered if this is normal or if anyone else that has coded ASS off has seen this same error (see attached PDF of error from Bimmerlink).

What it sounds like is you've disabled it, but the monitoring circuit is still active, creating that error. There's probably at least another item or two that needs to be changed to keep the system from detecting the situation.

Given that the EPA economy rating is based on the ASS working, taking it in for service will likely have them restore it to factory. If you can find how to disable the monitoring logic which should remove that error from recurring, you'd probably be okay from that viewpoint.

Thanks. I guess I had hoped that since this was an option that is available to be coded by BimmerCode that their app would take care of making sure that all necessary associated items that need to be coded would be taken care of via the app. Or, at a minimum that the app would notify me and point me to the items that needed to be coded in some type of multi-step process.

Send them a note...they programmer may be able to tweak the code. Also, make sure you're up to date with the latest version, as capabilities and bugs do get changed/fixed.

I did exactly that, and this was the response from Bimmercode:

"this error can not be prevented unfortunately and will be present as long as the start stop function is fully disabled."

Fortunately, it's a pretty easy item to turn enable or disable, so if the dealership re-enables ASS, I can easily disable it after. The error just annoys me, because I'm kind of an anal perfectionist.

Highly unlikely the dealer can or will enable ASS if they see this. Of course if they perform an iDrive update all coding for the effected ECUs will get wiped out.

I have a 2022 x5, auto stop start works, but I see no button.

Maybe it's built into the menu? I will check.

We are talking about the ability to disable ASS. When they removed the button then it is on all of the time (except when in a Sport mode/position).

Auto start stop is an essential part for fuel economy (and comfort) in hybrid functioning. Not having it doesn't make sense in a hybrid. Part of the functionality, like mentioned above is being able the switch of the ICE while slowing down for a traffic light (without hybrid technology it would only switch off at full stop)

The 45e doesn't have a have switch for ASS either. It is impossible to switch of. The button is replaced by a battery control button. But you don't need that in the mild hybrid.

I guess they took away the ability to switch off ASS in the mild hybrids just like in the 45e.

You can overrule it by switching the gear to sport like you did.

Ps. If you only have your car for 2 days shouldn't you wait a bit before driving in sport mode all day?

There is an alternative to sport mode? What is this you say???

NO auto stop start button on X5.

Get the Bimmercode app man, and purchase an adopter. That way you don't have to manually turn it off everytime you get in the car. It will take 2 minutes once you get the adopter.

I was referring to the original thread which reads "No auto stop/start button?"

Perhaps but you don't seem to understand how the start/stop system works. Reread my original post for the information.

I got my new XX a couple weeks ago and is also very mad that they eliminated that option but on YouTube a guy at a dealership recommends that you go into the sport- individual mode and set it up to be like the comfort mode, and in any of the sport modes the ridiculously stupid stop and start feature is turned off. But sadly the comfort mode now is useless because it has the built-in stop and start shut off

What's the issue with auto start stop? In my MY22 X5 it doesn't feel like the car shuts off completely, but it definitely goes quieter and AC stops blowing as hard. It's not really something I notice while driving unless I'm looking for it.

Agreed, as it restarts on the 48 volt battery it is hardly noticeable as you say what's the issue!!!.

I disabled the ASS on my 2022 X5 using Bimmercode. Even with the mild hybrid, it still seems to lurch a little bit when accelerating from a full stop, and I don't like it. It's pretty easy to tell if the ASS is engaged, because the tach goes to 0 when you are stopped. I tested it yesterday, and with the ASS coded off, I can run in Eco, Comfort, or Sport without the engine stopping.

Ok, got it.

My understanding is that once you've put it Eco mode, ASS returns

This is correct. Whenever returning to ECO after running another mode, ASS returns. Comfort and Adaptive modes return to your previous ASS setting for each mode if you enabled ASS memory when you coded.

I’ll have to try it again to verify, but pretty sure when I tested Eco yesterday and ASS did not return.

You are correct. When you code ASS off it will not come on in Eco Pro, or any other mode. What JimVR4 is referring to is coding ASS memory which is not applicable to vehicles without the Start/Stop button.
