Why is my Audi engine making a loud ticking noise?

I recently noticed that my Audi's engine is making a loud ticking noise, especially when I accelerate or idle. What could be causing this issue and how can I fix it?

The most common cause of a ticking noise in an Audi engine is due to low oil pressure. Make sure to check your oil level and refill if necessary. Additionally, check for any leaks or clogs in the oil system.

Another possible cause of a ticking noise could be a faulty or worn-out timing belt. It is recommended to have it inspected and replaced if necessary.
