Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and set the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Repair Steering Components

Inspect Steering Angle Sensor:
- Remove any panels covering the steering column if required.
- Disconnect the steering angle sensor connector.
- Test the sensor's resistance using a multimeter; compare readings to manufacturer specifications.
- If faulty, replace the steering angle sensor.
Check Power Steering Fluid System:
- Locate the power steering fluid reservoir and check the fluid level; top off with the recommended fluid if low.
- Inspect hoses for leaks; replace any damaged hoses and tighten connections as needed.
Examine Steering Rack and Tie Rods:
- Lift the vehicle using a jack and secure it with jack stands.
- Inspect the steering rack for leaks or physical damage.
- Check tie rods for wear or play; replace if necessary.

3. Reconnect and Reprogram (if applicable)

Reconnect any electrical connectors that were disconnected.
Reconnect the battery terminal.
Use the BMW-specific diagnostic tool to recalibrate the steering angle sensor if replaced.
