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

I recently noticed that my Audi A4's engine is making a ticking noise when idling. It's not insanely loud but it's noticeable. Has anyone else experienced this?

The ticking noise you are hearing could be caused by a few different things. It's important to get it checked by a mechanic to determine the exact cause, but it could be something as simple as a loose belt or a minor engine issue. It's always better to be safe and have it checked out before it potentially turns into a bigger problem.

I had the same issue with my Audi A4 and it turned out to be a faulty exhaust manifold gasket. It's not a serious issue, but it's important to have it replaced to avoid any future problems. It's an easy fix that any mechanic should be able to handle.
