Why is my Audi making a loud ticking noise when it starts?

I recently noticed that my Audi is making a loud ticking noise when I start the engine. It goes away after a few seconds, but it's a bit concerning. Any ideas on what could be causing this?

It's likely that your engine is just a bit cold and needs some time to warm up. This can cause a ticking noise that dissipates once the engine reaches normal operating temperature. Try waiting a few seconds before starting to see if the noise goes away.
