1. Fluid Leak: If there is a leak in the power steering system, the pump may continue to run to compensate for the loss of fluid. Check for any visible leaks in the hoses or lines connected to the power steering pump.
2. Low Fluid Level: Low power steering fluid can also cause the pump to run continuously as it struggles to maintain adequate pressure in the system. Check the power steering fluid level and top it up if necessary.
3. Faulty Pressure Switch: The power steering pressure switch monitors the pressure within the system and signals the pump to turn on or off as needed. If the pressure switch is faulty, it may send an incorrect signal to the pump, causing it to run constantly.
4. Malfunctioning Pump: In some cases, the power steering pump itself may be faulty and may need to be replaced. This can be the result of wear and tear, contamination, or other internal problems.
5. Electrical Issues: Electrical issues, such as a faulty relay or wiring problem, could also lead to the power steering pump running constantly. Check the electrical connections and wiring related to the power steering system.
If you are unable to identify the cause of the problem yourself, it is best to have the vehicle inspected by a qualified mechanic or at a Mini Cooper dealership to diagnose the issue and perform the necessary repairs.
