How do I reset my BMW X3's onboard computer?

I recently had some maintenance done on my BMW X3 and I noticed that some settings on the onboard computer were changed. How do I reset the computer to its default settings?

You can reset your BMW X3's onboard computer by following these steps: 1) Turn off your vehicle's engine and remove the key. 2) Press and hold the trip odometer button. 3) While holding the button, insert the key and turn it to the ON position. 4) Continue holding the button until 'RESET' appears on the onboard computer. 5) Release the button and press it again. 6) The onboard computer should now reset to its default settings.

Another way to reset your BMW X3's onboard computer is by disconnecting the negative terminal of your vehicle's battery for a few minutes and then reconnecting it. This should also reset the computer to its default settings.
