The electric power steering gear does not need to use steering oil. The electric power steering gear is completely powered by electronic components and electric motors, and no longer relies on hydraulic pumps and hydraulic pipelines, so it does not require hydraulic oil for lubrication or power.

For leaks at the hose or accessories, replacing the damaged hose or accessories is the best way to stop the leak. Aging or damage to the hose is one of the main causes of power steering pump leakage, so it is very important to check the condition of the hose regularly and replace it in time.

Abnormal The driver will feel that the steering wheel becomes unusually heavy, especially at low speeds or when parking. This situation not only makes driving more difficult, but also increases the danger of driving, especially in emergency situations.

Hydraulic power steering system is one of the earliest technologies to replace traditional rack and pinion steering systems. The system greatly reduces the force required by the driver to turn the steering wheel through the pressure provided by the hydraulic pump, thereby improving the comfort of control.

Damage to the power steering rack may affect the flow of power steering fluid. Under normal circumstances, the fluid circulates in the system to play a lubricating and cooling role. If the power steering rack is damaged, the fluid may not flow properly, causing localized temperature increases.

The wear of the rack may cause the meshing between the rack and the pinion to no longer be smooth, or even gaps or abnormal contact. Especially when driving on bumpy roads, the vibration of the vehicle will aggravate this wear, causing the power steering rack to make a "clicking" sound.

Normally, the rack of the power steering rack should not move excessively. The purpose of the rack design is to fix the steering rack so that it can move smoothly during the steering operation and provide assistance to the driver through a hydraulic or electric power system.

After turning off the power, it is recommended to wait a few minutes to ensure that the electric steering system is completely powered off. This step is critical to the smooth progress of the reset process and ensure that the electronic control unit (ECU) inside the system no longer retains any cache or error codes.

If the EPS warning light is on, it is recommended to use a car diagnostic instrument to read the fault code. The fault code can help determine the specific cause of the fault and guide the maintenance personnel to prescribe the right medicine.

Hydraulic power steering is a technology that BMW has traditionally adopted on a large scale. This system generates hydraulic pressure through a hydraulic pump driven by the engine belt, which then delivers hydraulic oil to the steering rack and pinion system through an oil pipe.
