Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface, and the ignition is off.
Disconnect the battery to avoid any electrical shorts.

2. Inspect and Tighten Steering Column Bolts

Locate the steering column access panel and remove it using a screwdriver.
Inspect the bolts securing the steering column for tightness.
Use a torque wrench to tighten the bolts to the manufacturer's specification (consult repair manual for specific torque values).

3. Replace Power Steering Fluid

Locate the power steering fluid reservoir and remove the cap.
Using a turkey baster, remove old fluid from the reservoir.
Refill the reservoir with new power steering fluid recommended by the manufacturer (typically CHF 11S for BMW).
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.

4. Replace Steering Angle Sensor (if faulty)

Disconnect the battery again for safety.
Locate the steering angle sensor, typically mounted on the steering column.
Remove the sensor by unscrewing any securing screws and disconnecting the electrical connector.
Install the new sensor by reversing the removal steps, ensuring it is properly aligned and secured.

5. Reassemble and Test

Reinstall the steering column access panel.
Reconnect the battery.
Start the vehicle and check for any warning lights on the dashboard.
Test the steering for smooth operation and responsiveness.
