What causes the poor fuel economy of Audi A2?

I've noticed that the fuel economy of my Audi A2 seems to be worse than what others have reported. I'm wondering what could be causing this issue.

There are a few potential causes for poor fuel economy in an Audi A2. One possible reason could be dirty air filters, which could restrict air flow and result in reduced engine performance. Another possibility could be a faulty oxygen sensor, which can affect the fuel-to-air ratio.

Another factor that can impact fuel economy is tire pressure. Make sure to regularly check and maintain the recommended tire pressure for your Audi A2. Under-inflated tires can cause increased rolling resistance and decreased fuel efficiency.

Have you changed your driving habits recently? Aggressive driving, such as frequent acceleration and braking, can significantly decrease fuel efficiency. Consider adjusting your driving style to be more gradual and smooth.
