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

I recently noticed that my 2018 Audi A1 makes a loud, rattling noise for a few seconds when I start the engine. It only happens on cold starts, and the noise goes away after a few seconds. Is this a cause for concern?

This is a common issue with Audi A1 engines, especially in colder temperatures. It's likely caused by a faulty timing chain tensioner that can be replaced for a relatively low cost at a certified Audi service center.

Don't worry, this noise is just the engine settling into its idle speed. However, if the noise persists for longer than a few seconds or becomes louder, it may be a sign of a bigger issue and you should take it to your mechanic for a check-up.
