1 Answers
BMW power steering systems can be broadly divided into two categories: one is the hydraulic power steering system, and the other is the electronic power steering system. 1. Hydraulic power steering system. Common causes of the "Power steering failure" warning include: 1. Low power steering fluid, such as hydraulic pipe leakage or damage to the fluid reservoir. 2. Faulty wiring or control of the ECO valve (electronic flow control valve). 3. Power steering pump failure. 4. AL control unit failure. 2. Electronic power steering system. Common causes of the "Power steering failure" warning include: 1. False alarm. You can try stopping the car, turning off the engine, waiting for 10 minutes, and then restarting. 2. Damaged steering torque sensor. 3. Defective or damaged steering gear. 4. Damaged reducer. 5. EPS control unit failure. 6. Faulty wheel speed sensor. 7. DSC control module failure. 8. Wiring faults or poor contact in steering system components, such as loose sensor connectors.
