Why is the BMW X4's engine making a loud knocking noise?

I recently bought a BMW X4 and have noticed that the engine is making a loud knocking noise. It seems to happen randomly and gets louder when I accelerate. Any advice on what could be causing this issue?

This could be caused by a variety of issues including worn out engine parts, low oil levels, or even a faulty fuel pump. I would recommend taking your car to a certified BMW mechanic to diagnose and fix the issue.
