Why is my Audi A1 making a rattling noise while idling?

I recently noticed that my Audi A1 is making a rattling noise when I'm at a stop. It seems to disappear when I start driving again. What could be causing this and how can I fix it?

This could be caused by a loose heat shield, which can rattle when the car is idling. Take your car to a mechanic to have them check and potentially tighten or replace the heat shield.

Another potential cause could be an issue with the exhaust system, such as a loose or broken muffler or exhaust pipe. Have a mechanic inspect and repair any damaged components to resolve the rattling noise.
