Why is my Audi A3 engine making a strange tapping noise?

I have noticed that my Audi A3's engine has started to make a tapping noise. What could be the cause of this and how can I fix it?

The tapping noise could be caused by a lack of oil or dirty oil. Make sure to regularly check and change your oil to avoid potential engine damage.

Another possible cause could be a loose or worn out timing chain. It is important to get this fixed as soon as possible to prevent engine failure.

Have you recently had any maintenance or repairs done on your car? It is possible that something was not put back together properly, causing the tapping noise. Take it back to the mechanic and have them check for any mistakes.
