Why is my Audi A3’s fuel consumption higher than advertised?

I've noticed that my Audi A3 uses more fuel than the advertised efficiency. Is there anything I can do to improve its fuel economy?

The reported fuel efficiency may differ depending on a variety of factors, such as driving habits, road conditions, and weather. However, you can try using efficiency modes while driving and avoiding rapid acceleration or braking, which can improve your fuel consumption.

Aftermarket modifications or accessories can also affect your car's overall fuel efficiency. Make sure to consult with a professional mechanic before installing any additional features, as they may not be compatible with your Audi A3.
