What should I do if my Audi A1 is experiencing engine trouble?

I recently noticed that my Audi A1's engine seems to be making strange noises and is not performing as well as it used to. I'm not sure what the issue could be. What steps should I take to address this problem?

First, make sure to check your oil levels and see if they need to be topped up. If that doesn't solve the issue, it's best to take your car to a trusted mechanic for a proper diagnosis.
