When driving my BWM, I noticed a knocking sound coming from the engine. I'm concerned that this could be a bigger issue. What could be causing this sound and how can I troubleshoot it?
ReplyFirst, you should check your oil level to make sure it's at the correct level. If the oil level is low, it could be causing the knocking sound. If the oil level is fine, then the knocking sound could be caused by low-quality fuel. Try filling up with premium fuel and see if the sound persists.
Another potential cause of engine knocking in a BWM is a faulty spark plug. Check your spark plugs to see if they need to be replaced. If the spark plugs are fine, then it's possible that the knocking sound is coming from worn engine bearings. In this case, it's best to take your car to a mechanic for further diagnosis.
