1. Access the Check Control Panel: Locate the check control panel on the dashboard of the BMW. It's usually a small display with buttons for various vehicle functions.
2. Select Secret Menu: Press and hold the "BC" button on the check control panel for about 5 seconds until the secret menu appears on the display.
3. Scroll to Oil Service Reset: Use the arrow buttons (usually labeled "1" and "0") to scroll through the menu options until you reach "Oil Service Reset."
4. Reset the EML: Once you're on the "Oil Service Reset" option, press the "BC" button again to reset the emissions malfunction light.
5. Verify the Reset: Turn the ignition key to the "ON" position (but don't start the engine) and observe the check control panel. If the EML is reset successfully, the light should turn off or disappear from the display.
It's worth noting that the secret menu and reset procedure can vary slightly depending on the specific BMW model and year, so it's always a good idea to refer to the owner's manual or a reliable source of BMW repair information for your specific vehicle.
