Seatbelt reminders and warning chimes reside in the (Advanced Crash Safety Module). Look for functions such as Gurtzustandsanzeige_Fahrer and similar. However, be aware that on certain later G‑series vehicles these parameters may have been removed from firmware. If they are absent, the modification is not possible on that firmware version. bmw esys coding cheat sheet
Before changing any code, always Read Coding Data and save a backup ( .ncd file) of the original ECU state.
To implement the parameters listed in the cheat sheet above, follow this sequence exactly: : Always read your Vehicle Order (VO) and
If you have questions about specific modules, tell me which you have (e.g., F30, F10) and what feature you're looking to change , and I can provide the exact codes.

BMW E-Sys is the professional engineering software used to configure, code, and flash Electronic Control Units (ECUs) for BMW F, G, and I-series vehicles. Unlike consumer apps, E-Sys allows for deep "Expert Mode" customization by modifying specific FDL (Function Data List) parameters within the car's modules.
| ECU | CAFD Folder | Function | Change | |---------|-------------|----------------------------------|------------------------------------------------------------------------| | DME/DDE | 3020 | TSA_MSA_Memory or TMC_MSA_Memory | Werte = 01 (remember last setting) instead of 00 (default reset to ON) |
: Coding ECUs causes high battery drain. Connect a clean 12V power supply (minimum 20A, preferably 70A+ for programming) to your car's battery to prevent voltage drops. A dying battery during coding can brick your ECUs. Required Software
Ensure the tailgate can be closed directly from the remote key – this often requires coding both the BDC and HKFM modules. Look for HKL_REMOTE_OPEN_CLOSE or similar.
