Why is my Ford Mondeo's engine making a rattling noise?

I recently noticed that my Ford Mondeo's engine has been making a strange rattling noise. It only happens when the car is idling or at low speeds. What could be causing this and how can I fix it?

This could be caused by a number of things, such as worn out spark plugs or a loose exhaust manifold. I recommend taking it to a mechanic for a thorough inspection.

I had the same issue with my Ford Mondeo. It turned out to be a problem with the timing belt tensioner. I suggest getting it checked out immediately as it could lead to more serious engine damage if left unchecked.

If your Ford Mondeo has a turbocharged engine, the noise could be coming from a faulty wastegate or a damaged turbocharger. These are both expensive repairs, so make sure to address the issue as soon as possible.
