Is there a lot of complaints about the failure of the BMW 3 Series steering power grid?

There have been, and there have been recalls, but the after-sales service is relatively good.

Due to the defect of the steering control module, the electronic power steering system may be abnormally closed, and the failure will cause the vehicle to lose steering assistance, so BMW China recalled more than 2,000 units of the 3 series produced in 2010-2012, and my car is also a car in this time period, but the after-sales response is not within the scope of the recall, my steering power will fail during the driving process, and it will recover intermittently after restarting, and go to the 4S store to test that there is no fault**.

Since it is a common problem, then everyone can form a group to go to the car quality network to protect their rights and give feedback.

This should be the case with the steering machine, steering column or booster pump and motor. If the manufacturer can not deal with it or the result is not satisfied, then it can only be dealt with by the third party, and there are more third-party parties in China, but the only credible is only the car quality network, after all, the number of complaints and credibility are very high, and the state also attaches more importance to the complaints of the manufacturer on the car quality network will also be dealt with in a timely manner. So if you want to really solve the problem of the vehicle, you can only go to the car quality network.

BMW 3 Series ( Check price |.)Detailed explanation of the model) If the steering power fails, you can directly go to the 4S shop or auto repair shop to find a technician who specializes in Mingye for maintenance. Power steering is a device that uses external power to generate steering assistance in order to reduce the operating force of the driver's actions on the steering wheel (also known as steering wheel).

Since mechanical hydraulic power assist needs to greatly reduce the power of the engine, people have developed a more energy-saving electro-hydraulic power steering system based on the improvement of mechanical hydraulic power assist. The steering oil pump of this system is no longer directly driven by the generator, but driven by the electric motor, and the electronic control system is installed on the previous basis, so that the size of the steering auxiliary force is not only related to the steering angle, but also related to the vehicle speed. The mechanical structure has added a hydraulic reaction device and a liquid flow distribution valve, and the new electronic control system includes a vehicle speed sensor, a solenoid valve, a steering ECU, etc.

The main components of the mechanical hydraulic power assist system are hydraulic pumps, oil pipes, pressure and fluid control valves, V-type transmission belts, oil storage tanks and so on. This type of power assist converts a part of the engine power output into hydraulic pump pressure, which exerts auxiliary force on the steering system to steer the tires. According to the different fluid flow modes in the system, it can be divided into atmospheric pressure hydraulic assistance and normal flow hydraulic assistance.

The common reasons for BMW steering power failure prompts are as follows:

1.Less directional pressurized oil, such as hydraulic management leakage, liquid reservoir damage, etc.; At this time, it is necessary to add directional boost oil;

Valve circuits, control failures, steering pump failures or AL control unit failures, etc. In this case, the source of the fault is located and the part is repaired or replaced.

3. If there is a false alarm, you can stop, wait for 10 minutes after the ignition is turned off, and then try to restart;

4.Damage to the steering torque sensor or defective steering gear or damage to the disassembly; At this time, you need to go to a repair shop to repair or replace;

5.Reducer damage, EPS control unit failure, wheel speed sensor failure or DSC control module failure; In this case, repair or replace the attachment;

6.Faulty wires or poor contact of steering system related parts, such as loose connectors for various sensors; Check the plugging of each component, and solve the loose problem in time. Millions of car purchase subsidies.
