Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a level surface and turn off the engine.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Locate the Leak
  • Sub-steps:
    • Remove any covers or shields obstructing access to the power steering system.
    • Clean the area around the power steering pump and hoses with a degreaser to identify the leak source easily.
3. Replace Leaking Components
  • Sub-steps:
    • If the power steering pump is leaking, remove the pump by loosening the mounting bolts and disconnecting the fluid lines. Replace with a new pump and ensure proper torque on the bolts (typically 18-22 Nm).
    • If hoses are leaking, replace them by loosening the clamps at both ends and installing new hoses. Ensure all connections are secure and without kinks.
    • For leaking steering racks, it may be necessary to replace the entire unit. Remove the old rack by disconnecting it from the steering column and the tie rods. Install the new rack and align it properly.
4. Refill and Bleed the System
  • Sub-steps:
    • Fill the power steering reservoir with the recommended fluid (usually CHF 11S for BMWs).
    • Start the engine and turn the steering wheel from lock to lock to purge air from the system.
    • Check the fluid level and top off as necessary.
5. Final Checks
  • Sub-steps:
    • Inspect all connections for leaks while the engine is running.
    • Reinstall any covers or shields that were removed.
    • Reconnect the battery terminal.
