Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the negative battery terminal to ensure safety while working on the electrical components.
2. Check and Top Up Power Steering Fluid
  • Locate the power steering fluid reservoir.
  • Remove the cap and check the fluid level; top up with the recommended fluid type (usually ATF or CHF fluid for BMW).
  • Replace the cap securely.
3. Inspect Power Steering Pump and Belt
  • Locate the power steering pump, usually found at the front of the engine.
  • Inspect the drive belt for cracks or excessive wear; replace if needed.
  • Use a socket set to remove the pump if it appears damaged or faulty.
4. Bleed the Power Steering System
  • After topping up the fluid, start the engine and turn the steering wheel from lock to lock multiple times to purge any air from the system.
  • Check fluid level again and top off if necessary.
5. Test and Replace Electric Power Steering Module (if applicable)
  • If the issue persists after checking fluids and bleeding the system, test the electric power steering module.
  • Remove any connectors and bolts securing the module.
  • Replace with a new module if it fails the functionality test.
