Start-Stop Default Off / Memory

By default, BMW's auto start-stop system activates every time you start the car — even if you turned it off last time. Coding can make the system remember your preference.

What It Does​

After coding, the start-stop system will:

  • Remember whether you had it on or off when you last drove
  • Or be set to default off every time you start the car

How to Code It​

BimmerCode (Easiest)​

  1. Connect and select the DME module
  2. Find "Automatic Start-Stop" or "Auto MSA"
  3. Set to "Last state" (memory) or "Default off"
  4. Code the module

E-Sys​

  1. Connect and read the DME module
  2. Open FDL Editor
  3. Parameter: MSA_MEMOREY (yes, BMW misspelled it) → set to aktiv
  4. Or: MSA_DEFAULT → set to aus (off)
  5. Code the module

Applies To​

All G series with start-stop:

  • G20, G30, G05, G06, G07, G80, G82, G70
  • Also works on F-series

Notes​

  • This is one of the most popular and lowest-risk coding changes
  • Does not disable start-stop permanently — you can still toggle it with the button
  • No effect on warranty
  • On 48V mild hybrid models (some 2020+ cars), the coding path is the same but the system behavior may differ slightly
  • PHEVs (e.g., 330e, 530e) have different start-stop logic tied to the hybrid system
