Why does my Audi A5 engine make a ticking noise at idle?

I recently noticed that my Audi A5's engine is making a ticking noise when idling. Is this something I should be concerned about?

It is not uncommon for Audi engines to make a ticking noise at idle. However, if the noise is excessively loud or persists even after the engine has warmed up, it could be a sign of a more serious issue.

One possible cause of a ticking noise at idle could be low oil levels. It's important to regularly check and top off your oil to ensure proper engine lubrication.

Old or dirty spark plugs can also cause a ticking noise in the engine. Consider replacing them if they have not been changed in a while.
