How do I reset the onboard computer of my Audi A1?

I heard that resetting the onboard computer can improve the performance of an Audi A1. But I'm not sure how to do it. Can someone walk me through the steps?

To reset the onboard computer of your Audi A1, start by turning off the ignition and removing the key from the ignition barrel. Then, press and hold down the odometer reset button on your dashboard. While holding the button down, turn on the ignition. After a few seconds, the Service Interval Display will show, keep holding the button until the display shows 'Reset Oil Change Interval?'. Then release the button, press and hold it again until it beeps. This should successfully reset your onboard computer.

Another easy way to reset the onboard computer of an Audi A1 is to disconnect the battery for 10-15 minutes. But be sure to have your radio code handy as it will need to be reprogrammed.

I usually reset my Audi A1's onboard computer by using a diagnostic tool like VAG-COM or VCDS. It's a more advanced method but can provide a more thorough reset of the system.
