The headlight washer is a very useful option, equipped with a Volkswagen Passat seventh generation vehicle. But it doesn't work every time. The mandatory condition for the activation of the headlamps of the headlamp on the Volkswagen Passat B7 is the dipped-beam headlamps switched on. If they are turned on, the headlight washer will trigger every fifth click on the windshield washer button.
It is not possible to deactivate the driver of the headlamps to Volkswagen Passat B7. This function can be deactivated through VAG-COM.
