Why is my BMW X5 engine making a weird noise when I accelerate?

I've noticed that whenever I accelerate in my BMW X5, the engine makes a strange noise. It's not a loud noise, but definitely noticeable. What could be causing this and is it something I need to get checked out?

There could be several reasons for this noise, but one common reason is that the engine might be low on oil. It's important to regularly check and maintain the oil levels in your X5. If the noise persists, it's best to take it to a mechanic for further inspection.

Another possible cause could be a problem with the spark plugs or ignition system. These components can wear out over time and can cause strange noises in the engine. I would recommend getting these checked and replaced if necessary.
