Why is my Audi A3 engine making a loud ticking noise?

I've noticed lately that my Audi A3's engine has been making a loud ticking noise when idling. It's becoming concerning, what could be causing this and is it something I should get checked out?

The ticking noise you're hearing could be due to a lack of oil in your engine. It's important to regularly check your oil levels and top up as needed. If the noise continues, it's best to take your car to a mechanic for further diagnosis.

Another possible cause could be a worn out timing belt or tensioner. These components are crucial to the smooth operation of your engine and should be replaced every 60,000-100,000 miles. If it's been a while since these were replaced, it's best to have them checked.
