Solution
1. Preparation
  • Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, power steering fluid, and a funnel.
  • Ensure the vehicle is parked on a level surface, and the engine is turned off.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Check and Refill Power Steering Fluid
  • Locate the power steering fluid reservoir (refer to the owner’s manual for exact location).
  • Remove the cap and check the fluid level against the markings on the reservoir.
  • If low, use a funnel to add the appropriate power steering fluid specified for BMW (usually CHF 11S).
  • Reattach the reservoir cap securely.
3. Inspect and Replace Power Steering Pump (if necessary)
  • Remove the drive belt from the power steering pump:
    1. Loosen the tensioner using a socket wrench.
    2. Slide the belt off the power steering pump pulley.
  • Disconnect the power steering pump from the steering system:
    1. Remove the bolts securing the pump to the engine.
    2. Disconnect the power steering lines (ensure to have a catch pan for any fluid).
  • Install the new power steering pump:
    1. Position the new pump and secure it with bolts to the engine.
    2. Reconnect the power steering lines and torque to manufacturer specifications.
  • Reinstall the drive belt, ensuring it is properly aligned on all pulleys.
4. Electrical System Check
  • Reconnect the negative battery terminal.
  • Use a multimeter to check the voltage at the power steering module.
  • Ensure that the connections to the EPS motor and control module are secure and free of corrosion.
5. Clear Error Codes and Test Drive
  • Use the OBD-II scanner to clear any stored error codes.
  • Start the vehicle and allow it to idle.
  • Perform a test drive to ensure the EPS light remains off and steering is smooth.
