Why does my Audi A4 engine make a clicking noise during startup?

I have noticed that my Audi A4 makes a clicking sound whenever I start it up in the morning. The noise goes away after a few minutes of driving. Is this a cause for concern?

This could potentially be a sign of a weak battery or a starter issue. It is best to have it checked by a mechanic to determine the exact cause.

It's normal for an engine to make some noise during startup, but excessive clicking could indicate a potential issue. Have a professional take a look at it just to be safe.

It's possible that there is a problem with the engine's valves or lifters, causing the clicking noise. It's best to have it checked by a mechanic to prevent any further damage.
