^ Headlight reflector detached or broken.
^ Alignment of the headlight to the body not correct.
^ Vibrations of the vehicle at idle.
Production Solution

Service
1. Check the mounting points of the headlight for correct fit.
2. Check the mounting of the reflector inside the headlight assembly.
3. Align the headlight to the body.
4. Position the headlight assembly with rubber wedges as shown in Figure 1 to isolate the vibration.
Observe the following points:
^ Minor vibrations of the light beam are still possible. This is normal.
^ A replacement of the headlights under warranty is only permitted if the reflector of the headlight is detached or broken.
