Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface.
Safety note: Disconnect the negative battery terminal to prevent any electrical issues.

2. Check Tire Pressure

Use a tire pressure gauge to measure each tire's pressure.
Adjust tire pressures to match the manufacturer’s specifications as indicated on the driver's side door jamb.

3. Inspect and Adjust Alignment

Tools Required: Alignment machine, socket set, torque wrench.

Position the vehicle on the alignment machine.
Follow the alignment machine's instructions to measure the alignment angles (caster, camber, and toe).
If adjustments are needed:
- Loosen the adjustment bolts on the control arms or tie rods as necessary.
- Adjust the toe angle to the manufacturer's specifications (typically 0.10-0.20 degrees for most BMWs).
- Re-tighten the adjustment bolts to the manufacturer's torque specifications.

4. Test Drive

After adjustments, take the vehicle for a test drive to ensure the steering wheel is centered and the vehicle tracks straight.
