Why does my BMW X3 engine make a loud knocking noise?

I have noticed that my BMW X3's engine has been making a loud knocking noise while idling. It seems to get worse when I accelerate and it's concerning to me. Any ideas on what could be causing this and how to fix it?

Hi Maria, I understand your concern about the loud knocking noise coming from your engine. There are a few possible causes for this issue such as worn out or damaged engine parts, low oil levels, or a faulty crankshaft position sensor. It's important to address this issue as soon as possible to prevent any further damage to your engine.

Hey Maria, I've had the same issue with my BMW X3 before. It turned out to be a problem with the timing chain tensioner. I suggest taking your car to a trusted mechanic who specializes in BMWs to have it checked and repaired if needed.

Hi Maria, I had a similar experience with my BMW X3 and it turned out to be a misfiring spark plug. This caused the engine to make a knocking noise and also affected the performance of my car. I recommend getting your spark plugs checked and replaced if necessary.
