How is the fuel consumption on the Audi A4 calculated?

I recently purchased a new Audi A4 and I'm trying to track my fuel consumption with the onboard computer. However, I'm not sure how the car calculates this and what factors are taken into account. Can anyone explain the process to me?

The fuel consumption on the Audi A4 is calculated using a combination of factors, including your driving habits, average speed, and engine load. The onboard computer takes sensor readings and data to provide an estimate of your fuel consumption.

To accurately track your fuel consumption, make sure to reset your trip computer each time you fill up your tank. This will give you a more accurate reading as it takes into account your most recent driving habits and conditions.
