Why does my Audi A3's engine make a strange noise when idling?

I've noticed that my Audi A3's engine makes a strange noise when the car is idling. It's almost like a rattling or clicking sound. Is this cause for concern, or is it a normal part of the car's operation? Has anyone else experienced this issue? Any insights would be greatly appreciated. Thanks!

It's possible that your car's oil level is low, and the engine is not getting enough lubrication. Check the oil level and top it up if necessary. If the noise persists, it's best to take your car to a mechanic for a professional inspection.
