BMW 7 Series: Headlight Washer System
ADJUSTING WASHER JETS FOR HEADLIGHT WASHER SYSTEM
NOTE: The washer jets of the headlight washer system have been adjusted at the factory and normally this setting is not altered (except by an accident). The nozzles therefore do not have to be adjusted.
The washer jets do not have to be adjusted even in the event of replacement as the washer jets themselves and the telescopic nozzle form a single unit (highpressure nozzle) and are already preset.
