How do I fix the rattling noise in my Ford Mondeo's engine?

I have a Ford Mondeo and recently noticed a rattling noise coming from the engine. It seems to be more pronounced when the car is idling or when I accelerate. What could be causing this and is there a way to fix it?

It's likely that the noise is coming from a loose or worn out engine component. You should take your car to a trusted mechanic to have it checked out.

I had a similar issue with my Ford Mondeo and it turned out to be a loose heat shield. I was able to tighten it myself and the noise went away.
