Solution

1. Preparation

Tools Required: Socket set, wrench set, fluid catch pan, OBD-II scanner, flashlight.
Safety Warnings: Disconnect the battery before starting work to avoid electrical shorts. Allow the engine to cool before beginning repairs.

2. Locate the Leak

Sub-steps:
1. With the vehicle on a level surface, lift the front of the vehicle using a jack and secure it with jack stands.
2. Clean the area around the power steering components to remove old fluid and debris for better visibility.
3. Start the engine and turn the steering wheel from lock to lock while observing components for any leaks.

3. Repair the Leak

Sub-steps:
1. If the leak is from a hose, disconnect the affected hose using the appropriate wrench.
  - Tools Required: Hose clamp pliers, wrench set.
2. Replace the damaged hose with a new OEM or compatible part. Ensure all clamps are secure.
3. If the leak is from the power steering pump, remove it by loosening the mounting bolts and disconnecting the fluid lines.
  - Torque Specification: Refer to the vehicle's service manual for correct torque values when reinstalling.
4. Replace the power steering pump if damaged or leaking. Install the new pump and reconnect fluid lines.
5. If the leak is from the steering rack, it may require rebuild or replacement, which involves removing the rack from the vehicle.

4. Refill and Bleed the System

Sub-steps:
1. Refill the power steering fluid reservoir with the recommended fluid type (typically BMW CHF 11S).
2. Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
3. Check the fluid level again and top off as necessary. Look for any signs of leaks during this process.
