How to fix low engine power in an Audi A1?

I have noticed that my Audi A1 is not performing as well as it used to. The engine power seems to have decreased significantly. What could be causing this issue?

You may need to check your air filter and clean or replace it if necessary. A clogged air filter can significantly affect your engine's performance.

Have you checked the fuel filter? It may be clogged and affecting the fuel supply to your engine. Consider replacing it to improve engine power.

Low engine oil levels or poor quality oil can also contribute to decreased engine power. Make sure to regularly check and change your engine oil for optimal performance.
