  1. Call up Start (main) menu
  2. Push controller in up direction for at least 10 s
  3. Rotate controller, 3 notches to the right
  4. Rotate controller, 3 notches to the left
  5. Rotate controller, 1 notch to the right
  6. Rotate controller, 1 notch to the left

b) F30 without navigation, or with Business Navigation This implies that you have an idrive controller that cannot slide up or down

The instructions are basically the same, but instead of pushing the controller in the up direction, which is not possible, you need to push the controller to the left and keep it there for 10 seconds. So the instructions become;

  1. Call up Start (main) menu
  2. Push controller in the left direction for at least 10 s
  3. Rotate controller, 3 notches to the right
  4. Rotate controller, 3 notches to the left
  5. Rotate controller, 1 notch to the right
  6. Rotate controller, 1 notch to the left
  7. Rotate controller, 1 notch to the right
  8. Press controller once
  9. The Service menu is now added as the last submenu to "Settings"
