Why does my Audi A4's engine make a clicking noise when it's idling?

Recently, I noticed that my Audi A4's engine makes a clicking noise when it's idling. It's not very loud, but it's definitely noticeable. Has anyone else experienced this issue? Is this something I should be concerned about?

The clicking noise is most likely caused by an issue with the valve train. It could be due to worn valve lifters or pushrods. I recommend visiting a certified mechanic to diagnose and fix the issue.

I had the same issue with my Audi A4. It turned out to be a faulty ignition coil. I suggest getting it checked and replaced if necessary.
