Why is my Ford Mondeo making strange noises while idling?

I recently noticed that my Ford Mondeo has been making strange noises whenever I'm idling at a traffic light or in a parking lot. It almost sounds like a rattling or knocking noise. What could be causing this and how can I fix it?

It's possible that your engine is not getting enough oil, which can cause the internal components to make strange noises. I would recommend getting your oil level checked and also getting an oil change if it's been awhile.

Another possible cause could be a loose or worn out belt in your engine. This can also make rattling or knocking noises. I would recommend taking it to a mechanic to get it checked out and possibly replaced.

Check your exhaust system as well. A loose or damaged exhaust pipe can also make strange noises while idling. It's important to get this fixed as soon as possible as it can affect your car's performance and emissions.
