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

I have noticed that my Audi A1's engine is making strange noises while I am driving. It sounds like a knocking or tapping sound. What could be causing this and how can I fix it?

It is possible that your engine is low on oil or that there is an issue with your oil pump. I recommend checking your oil levels and having your oil pump inspected by a professional mechanic.

Another possibility is that your timing belt or chain is worn out or damaged. This can cause strange noises in your engine and should be checked by a mechanic as soon as possible.

It could also be a sign of a more serious problem, such as engine damage or a faulty component. It is best to have a mechanic diagnose and repair the issue to prevent further damage.
