Why is my BMW 2 Series engine making a rattling noise?

I recently noticed that my BMW 2 Series engine has started making a strange rattling noise. It only happens when I accelerate and becomes louder at higher speeds. Is this a sign of a serious problem? What could be causing this and how can I fix it?

Hi Hannah, the rattling noise could be coming from various issues such as a loose heat shield, worn out engine mounts, or even an internal engine problem. I would advise you to take your car to a mechanic for a thorough diagnosis. It's always better to address potential issues before they become major problems.
