Telescopic nozzle component description - GF82.15-P-2150GZ
MODEL 164.1/8 with CODE (600) Headlamp cleaning system up to model year 2008/YoM 07
Shown on model 164.1
Location
The telescopic nozzles are located below the left front lamp unit (E1) and right front lamp unit (E2), concealed by flaps behind the bumper.
Design
The telescopic nozzle is a hydraulically extending telescopic element with integrated return springs. It does not have any electrical connection.
Function
Water pressure drives the telescopic nozzles initially into the cleaning position. In doing so the flaps in the bumper are opened. Then, an additional increase in pressure at each telescopic nozzle opens a valve and the washer fluid is sprayed. Following a pressure drop, the telescopic nozzles are retracted with the aid of return springs to their starting position and the flaps in the bumper are closed by the spring action.
