I recently noticed a knocking noise coming from my BMW X5's engine while I accelerate. It's been happening for a few days now and I'm worried it could be a serious issue. What could be causing this and what should I do about it?
ReplyIt's possible that your engine is experiencing knocking due to low quality fuel or incorrect octane rating. Try using a higher octane fuel and see if the noise persists.
Another possible cause of engine knocking is a faulty ignition timing. It's best to have a professional mechanic check and adjust the timing if necessary.
