BMW 1-Series hidden menu (E81, E82, E87, E88) procedure

1. Turn the ignition on.
2. Press and hold trip reset button. Instrument cluster will show warning sign, next oil sign.
3. Release the button when FGSTNR appears on the display. After few seconds a 7-digit number will appear. Last 5 digits are also the end of your cars VIN.
4. Add up last 5 digits together (1+2+3+4+5=15).
5. Press and hold trip reset button until 01.__ is displayed, then immediately press trip reset button couple of times to navigate to position 19.__. “LOCK ON” will be displayed. After couple of seconds “CODE: 00” will appear.
6. Use trip reset button to enter your code (added up last 5 digits from 01.__ position).
7. Now the hidden menu is unlocked and you can browse all its tests.
