What causes the abnormal noise when the BMW X3 is running?
1 Answers
BMW X3 running with abnormal noise may be caused by the following reasons: Oil problem: The engine oil does not fully lubricate all parts of the engine. It takes some time for new oil to evenly lubricate all components. If the noise persists after a while, it may indicate severe wear. Additionally, cleaning the internal parts of the engine can enlarge the gaps caused by wear. Poor sealing: Large gaps and poor sealing can lead to deteriorating engine conditions, which may also cause noise. It is recommended to have it checked at a repair shop. Maintenance issue: Lack of maintenance may result in excessive carbon buildup (such as in the engine, throttle, spark plugs, etc.). Cleaning at a repair shop can resolve this issue.
