The BMW Access Hidden (Secret) Menu is a menu that provides advanced information for BMW vehicles. This menu is not commonly known and is not part of the standard menu options that can be accessed through the vehicle’s infotainment system. However, it provides valuable information about the vehicle’s systems, components, and performance, allowing technicians and car enthusiasts to diagnose and repair issues more effectively. Accessing the BMW Hidden Menu requires specific knowledge but once unlocked, it provides a wealth of information and allows for an in-depth analysis of the vehicle’s performance.
- Figure out the CODE. Add the last 5 digits of your VIN. This is the CODE that you will need to enter later to unlock your BMW hidden menu. Example: If your BMW VIN is XXXXXXXX22327, the CODE will be 16. (2+2+3+2+7=16 )
Please turn on the key to position I (ACC). If your BMW has Start/Stop button, press it twice without pressing the brake pedal.
- Press and hold the odometer reset button for ten seconds. Release the button when FGSTNR shows up on the center display. A seven-digit number will appear, showing the last five digits of the VIN.
- Unlock the hidden menu. Press and hold the reset button until item 01 is displayed. Then toggle the reset button multiple times until you reach Unlock meu. It will be either menu 4 or 19.
- You will see Lock ON—code 00. Use the reset button to change the CODE to the total of the last five digits of your VIN. Hidden Menu Is unlocked. If the OBC menu is not UNLOCKED, you can only see menus 01 and 02.
These instructions will work on many BMW models, including E81, E82, E87, E88, E60, E61, F01, E70, etc.
