What are the reasons for mini power steering failure?
2 Answers
mini power steering failure mainly has the following reasons: 1. False alarm, you can stop the car, turn off the engine and wait for 10 minutes before restarting. 2. Damage to the steering torque sensor; defects or damage to the steering gear. 3. Damage to the reducer; EPS control unit failure; wheel speed sensor failure, etc. Other reasons include: 1. DSC control module failure; 2. Wiring faults or poor contact in steering system components, such as loose sensor connectors. 3. Power steering pump belt breakage. If the belt breaks, the vehicle can still be driven if the power steering pump has a separate belt, but without power assistance, it should be repaired as soon as possible; if it is a combined belt (connected to the air conditioning and generator), the vehicle should only be driven for a short distance and time, as the vehicle is in a non-generating state, and the battery will run out, causing the vehicle to stall.
I've dealt with quite a few cases of MINI power steering failure. The most common issue is problems with the power steering pump, such as a loose or broken belt—you'll hear squeaking when turning the wheel in these cases. The hydraulic system is also prone to trouble; insufficient power steering fluid or leaks can make the steering wheel heavy, especially in older cars where aging hoses are susceptible to seepage. Cars with electronic power steering are more complex—faults in the torque sensor or control module can cause the system to misjudge, and poor contact in wiring connectors is also a frequent culprit. Once, I encountered a car where a blown fuse cut power to the steering assist, and replacing the fuse fixed it. If you face this situation, never force the car to drive. First, turn off the engine and check the fluid reservoir level. If you're unsure, just call a tow truck immediately—low-speed turns are particularly dangerous when power steering fails.
