Why does my Audi A3's engine make a clicking noise when starting?

I recently purchased a used Audi A3 and noticed that the engine makes a clicking noise when I start it. It goes away after a few seconds, but I'm wondering if this is a cause for concern or if it's normal for this model.

The clicking noise is most likely from the starter motor engaging and disengaging. It is a common sound in Audi A3 engines and is generally not a cause for concern. If it becomes a persistent and loud noise, it may be worth checking with a mechanic.
