I have little problem with disable start stop in F25 - X3.

I add OMSA to HO-word in E-sys, change MSA_memory & MSA_default on active in cas, but button S&S system reset when ignition is off, no light when ignition on, I must manual off, don't remember last config.

Any idea ?
Thx for help.

When doing this on other chassis. you shouldnt have to activate msa_default on. Only msa_memory to active.

Hi carat10,

Did You manage to solve Your problem? I had the same issue recently, tried with OMSA, MSA_MEMORY and even MSA_DEFAULT_OFF, but every time after turning the engine on the AutoStartStop button LED is off (which means that ASS is enabled).

The same thing worked without any trouble on a couple of F10s...

Thanks.

If the MSA memory function isnt working properly, update your cars software if the i-level is beforte 13-07. MSA coding wont work before that.

For Auto Start Stop (ASS), you usually set either TCM_MSA_DEFAULT_OFF or TC_MSA_MEMORY, NOT both.

TCM_MSA_DEFAULT_OFF (FEM_BODY for F20/F30, BDC_BODY for F15/F25)

• aktiv = ASS 'OFF' by default
  
• nicht_aktiv = ASS 'ON' by default

TCM_MSA_MEMORY (FEM_BODY for F20/F30, BDC_BODY for F15/F25)

• aktiv = ASS remembers if set to 'ON' or 'OFF' from previous shutdown
  
• nicht_aktiv = ASS does not remember

TCM_MSA_ECO_MODE (BDC_BODY for F15/F25)

• aktiv = ASS 'OFF' by default in EcoPro Mode
  
• nicht_aktiv = ASS 'ON' by default in EcoPro Mode

TC_MSA_MEMORY (CAS for F10/F11)

• aktiv = ASS remembers if set to 'ON' or 'OFF' from previous shutdown
  
• nicht_aktiv = ASS does not remember

TC_MSA_DEFAULT_OFF (CAS for F10/F11)

• aktiv = ASS 'OFF' by default
  
• nicht_aktiv = ASS 'ON' by default

MSA_VERFUEGBARANZEIGE_ENABLE (KOMBI)

• nicht_aktiv: disables ASS notification in Instrument cluster
  
• aktiv: enables ASS notification in Instrument cluster

Normaly, it´s enough to add "OMSA" to HO-Wort of VO and code CAS or FEM.

Hi,

Thanks for Your answers. I'm aware, more or less, of possible ways to disable ASS.
My problem is that neither TC_MSA_MEMORY, TC_MSA_DEFAULT_OFF nor OMSA did not work on the F25 car I tried. The car's i-Level is F025-11-03-511. Other coding options, even in CAS, worked.

Need newer software. Doesn't work until I level 13-07

You need a code from BMW.

[MicRofT]

OK. I will try to organise an upgrade place for my friend and return here with some feedback.

Thanks

A code? What code? What for?
