BMW X5 knocking noise on driver side after water pump, oil, spark plugs, and coils replacement on BMW X5

Some BMW X5 owners report experiencing a knocking noise on the driver's side after replacing the water pump, oil, spark plugs, and coils. This noise may be attributed to several factors, including worn-out suspension components such as bushings, control arms, or stabilizer links. Additionally, issues with engine components, like incorrect ignition timing or worn spark plugs, can also lead to knocking sounds. Owners should ensure that the water pump was installed correctly to avoid leaks or malfunctions, and using the correct type and amount of oil is crucial to prevent further engine knocking. Furthermore, proper installation of coils and spark plugs is necessary to maintain engine performance. If the knocking persists, it is recommended to have the vehicle inspected by a qualified mechanic for a thorough diagnosis and resolution.
