Why is my Audi A8 engine making a ticking sound?

I recently noticed that my Audi A8 engine is making a ticking sound. It's not too loud, but it's definitely noticeable. Should I be concerned? What could be causing this? Is it something that I should get checked out by a mechanic?

It's possible that the ticking sound is just normal engine noise. However, it's always best to err on the side of caution and have it checked out by a mechanic. They can take a closer look and determine if there is a potential issue that needs to be addressed.
