How do I check the fuel efficiency of my Audi A3?

I recently bought a used Audi A3 and want to make sure I am getting the best fuel efficiency. Is there a way to check this on the car's system or do I need to calculate it manually?

To check your Audi A3's fuel efficiency, simply go to the car's on-board computer system and navigate to the 'Efficiency' section. Here, you will find information on your average fuel consumption and how many miles you have left until you need to refuel. It's always a good idea to reset the car's computer after each fill up to get the most accurate readings.

I recommend calculating your Audi A3's fuel efficiency manually by tracking the miles driven and fuel used between fill ups. This will give you the most accurate data and allow you to compare your car's performance against the manufacturer's official fuel efficiency ratings.
