Why does my Audi A1 make a rattling noise when idling?

I've noticed that my Audi A1 makes a rattling noise when idling, but it stops when I start driving. Is this something I should be concerned about and should I take my car to a mechanic?

It's possible that there is an issue with your car's engine or exhaust system. It's best to have a professional mechanic inspect your car to determine the exact cause of the rattling noise.

It could also be something as simple as a loose heat shield. Have a mechanic take a look to confirm and fix the issue.

It might be a worn out belt or pulley in your car's engine. This can lead to more serious problems if not addressed, so it's best to have a mechanic check it out.
