What are the causes of BMW X5 powertrain failure?
1 Answers
BMW X5 powertrain failure causes: 1. Abnormal speed in hydraulic transmission system: For faults caused by speed abnormalities, it is necessary to individually adjust variable structures such as throttle valves, relief valves, variable displacement pumps, and speed control valves, then compare their speed range values with technical reference values for analysis. 2. Abnormal operation in hydraulic transmission system: For faults caused by operational abnormalities, observe the operating status of relevant system actuators to determine normalcy, identify malfunctioning directional valves, and then inspect travel control to locate abnormal areas in the hydraulic system. 3. Abnormal pressure in hydraulic transmission system: To determine if faults are caused by pressure abnormalities, use a pressure gauge to measure pressure values at reserved test points on system pipelines, then analyze differences between measured values and standard values to identify the fault location causing abnormal pressure.
