How do I disable Auto Start / Stop on 2020 M340i?

I have been trying everything to turn off the Auto Start / Stop feature of my M340i. My wife has a 2017 X1 which can be easily turned off and the memory keeps it off at all times; even after her car is turned off and on again. When I turn mine off, it stays off until I turn off the car. When I restart the car, the feature is on again. Is there a way to turn it off permanently?

Thanks.

Coding it off is the only way.

I just switch to sport or sport plus every time I drive it. Yes annoying but it's automatic now.

ASS Won't Stay Off

Hi,

One of the first things I did on my '14 F30 was to code the ASS Memory so the car wouldn't turn off & on at stop lights.

So when I got my '20 M340, that was one of the first things I coded. Of course, it's in the DME_BACK2 module, which means that if you're coding with E-Sys, you have to make sure the engine is off before you actually code; of course, using Bimmercode, you just have to be in the Diagnostic mode (three quick pushes on the engine on button with no pedals touched).

Well, I have done it multiple times on my car, using either means of coding and I always get the same result:
  • I press the ASS button (turning it off & engaging the orange light)
  • Drive around
  • Shut the car down & as I walk away Comfort Access locks the car
  • When I return, I can see the ASS orange light on
  • Then, if I open either of the front doors, the ASS light goes off (as well as, ASS)

Like I said, I have tried coding it many times. I have even VO coded the DME_BACK2 module and then FDL coded TCM_MSA_Memory from NichtAktiv to Aktiv -- all to no avail

Appreciate any ideas??

Bimmercode worked for me without any issues.

I drive in comfort when I got to work and back since it's a long comute so I would like to have it off at all times. Coding is done at the dealer? Or can users do it?

Yeah I know. I have gotten used to turning it off every time now but having to do that plus that light on, is very annoying.

Putting in s or sp automatically turns it off

correct. The thing is that I drive to and from work every morning with lots of traffic, so I keep it in comfort, which does not have that automatic function. I put it in Sports mode when there is less traffic and I can step on the gas.
