I have a knocking noise coming from my Ford S-Max engine, what could be causing it?

I have noticed a knocking noise coming from the engine of my Ford S-Max. It seems to happen when the engine is idling or when I accelerate. The noise is quite loud and it's been going on for a couple of weeks now. What could be causing this and should I be concerned?

The knocking noise could be caused by a variety of issues, such as worn engine components or low oil levels. It's best to take your Ford S-Max to a mechanic for a proper diagnosis.

I had a similar issue with my Ford S-Max and it turned out to be a loose belt causing the knocking noise. Check your belts and see if they need to be tightened or replaced.
