I recently purchased a BMW X7 and have noticed a rattling noise coming from the engine. It occurs randomly and seems to be more prevalent when the engine is cold. What could be causing this and how can I fix it?
ReplyIt is possible that the rattling noise is being caused by a loose component in the engine, such as a pulley or belt. It could also be a sign of low oil levels or a faulty oil pump. I suggest taking your X7 to a mechanic to diagnose and fix the issue as soon as possible.
I had a similar issue with my BMW X7 and it turned out to be a malfunctioning valve in the engine. I recommend taking your car to a certified BMW dealership for a thorough inspection and potential replacement of the valve.
