Why is my Audi A2 experiencing poor fuel efficiency?

My Audi A2 seems to be consuming more fuel than normal. I have checked the tire pressure and ensured regular maintenance, but the issue persists. What could be causing this and what can I do to improve the fuel efficiency?

First, make sure you are using the recommended grade of fuel for your Audi A2. Using a lower grade fuel can decrease fuel efficiency. Also, check for any potential leaks in the fuel line or emissions system that could be causing the issue. In addition, check your air filter and clean or replace it if necessary. And finally, consider adjusting your driving habits such as avoiding aggressive driving and maintaining a steady speed as these can also impact fuel efficiency.
