Why is my Audi A1's engine making strange noise?

I've been experiencing a strange noise coming from my Audi A1's engine. It sounds like a rattling or clicking noise. What could be causing this and how can I fix it?

It's possible that there could be an issue with your engine's timing belt. This is a crucial component that helps your engine run smoothly. It's important to have it checked and replaced if necessary to avoid potentially serious damage.

Another possible cause of a strange engine noise is low oil levels or dirty oil. Make sure to check your oil regularly and have it changed according to your manufacturer's recommended schedule.
