Why is the BMW X3's engine making a strange noise?

I recently noticed that my BMW X3's engine is making a strange noise. It's like a rattling sound whenever I accelerate. What could be causing this and how can I fix it?

It's possible that your car's engine is just dirty and needs a good cleaning. Try using a fuel injector cleaner or taking it to a professional for a thorough engine cleaning.

Check your engine's oil level. Low oil can cause the engine to make strange noises. If it's low, top it off and monitor it closely. If it continues to happen, there may be a leak that needs to be addressed.
