How to diagnose and fix strange noises in my Audi A3 engine?

I recently noticed some strange noises coming from my Audi A3 engine. It's making a clicking sound that is getting louder and more frequent. What could be causing this and how can I fix it before it becomes a major problem?

It's possible that the clicking sound is due to a worn out timing chain tensioner. This is a common issue in Audi A3s and can cause serious damage if not addressed. I recommend taking your car to a reputable mechanic for a diagnosis and repair.
