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

I recently purchased a 2020 Audi A4 and noticed that when I start the engine, there is a consistent clicking noise coming from the engine. It goes away after a few seconds but I'm concerned about it. Is this normal or should I have it checked out?

The clicking noise you are hearing is most likely the sound of the fuel injectors firing up. This is a common sound in newer Audi models, and as long as it stops after a few seconds, there is no need to worry. However, if you notice any other unusual noises or performance issues, it's always a good idea to have it checked out by a mechanic.
