How can I reset the onboard computer in an Audi A2?

Recently, my Audi A2 has been showing some incorrect data on the onboard computer, such as fuel levels and temperature. I suspect it needs to be reset. How can I do this?

To reset the onboard computer in your Audi A2, first switch off the engine and remove the keys from the ignition. Next, locate the fuse box in the driver side footwell and remove the fuse for the onboard computer. Wait for 30 seconds before replacing the fuse and starting the engine again.

You can also reset the onboard computer by disconnecting the car's battery for a few minutes. This will wipe all current data and settings, and may also reset any other issues with the car.
