Why does my Audi A6's engine make a clicking sound?

I've noticed that my Audi A6's engine makes a clicking sound when I start it up. It only lasts for a few seconds, but I'm concerned that it could be a sign of a bigger problem. Can anyone tell me what might be causing this and if it's something I should be worried about?

It's normal for your Audi's engine to make a clicking sound when starting up. It's just the sound of the valves and lifters adjusting to the engine's oil pressure. However, if the sound continues or gets louder, it could be a sign of a more serious issue such as low oil pressure or a faulty valve.
