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

I noticed that my Ford Mondeo's engine has been making a loud knocking noise lately. It seems to be coming from underneath the hood and I'm worried it could be a sign of a bigger issue. What could be causing this and what steps should I take to fix it?

It sounds like your Ford Mondeo's engine could be experiencing a mechanical issue. It's best to take it to a certified mechanic to get it checked out.

It could be something as simple as low oil levels or a loose belt. Make sure to check your engine oil and have all belts tightened if needed.

I had a similar issue with my Ford Mondeo and it turned out to be a faulty fuel injector. I highly recommend getting it checked by a mechanic as soon as possible to avoid any potential damage to your engine.
