Why is my Audi's engine making a ticking sound?

I've noticed that my Audi's engine has started making a ticking sound, especially when I accelerate. What could be the cause of this and should I be concerned?

The ticking sound could be due to low oil levels in your engine. It is important to regularly check and top up your oil to avoid any potential engine damage.

Another possible cause could be a problem with your timing belt or chain. It is recommended to have this checked by a professional mechanic to avoid any further issues.
