how to fix my BMW 5 Series F10/F11 (2010-2017) if the steering wheel is hard to turn

Solution

1. Preparation

• Tools Required: Wrench set, OBD-II scanner, fluid catch pan, safety gloves.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to avoid electrical shorts.

2. Inspect Power Steering Fluid

• Locate the power steering fluid reservoir.
• Remove the cap and check the fluid level; top off with the recommended fluid if low.
• Inspect fluid for contamination; if dirty, it may need to be flushed.

3. Check for Leaks

• Use a flashlight to inspect hoses and connections for signs of leakage.
• If leaks are found, replace damaged hoses or seals as necessary.
• Clean any spilled fluid to prevent slipping hazards.

4. Inspect Power Steering Pump and Belt

• Locate the power steering pump; check for signs of wear or damage.
• Inspect the drive belt for cracks or fraying; replace if necessary.
• If the pump is noisy or not producing pressure, it may require replacement.

5. Check Steering Rack and Components

• Visually inspect the steering rack for any visible damage or leaks.
• Verify that all steering linkage components are secure and free of play.
• If any components are worn, replace them according to manufacturer specifications.

6. Reconnect and Test

• Reconnect the battery and start the engine.
• Turn the steering wheel from lock to lock to bleed air from the system.
• Check for proper operation and fluid level again, topping off as needed.
