Why does my Audi A1 engine make a rattling noise when starting up?

I've noticed that my Audi A1 makes an unusual rattling noise when I start the engine. It soon goes away, but it still concerns me. Is this something I should be worried about?

The rattling noise is most likely due to a worn timing chain tensioner. It's a common issue with Audi A1 engines.
