Mercedes-Benz W22 Headlamp Washer Nozzle A2218601447 - Used Original Parts

Diagnosis and Common Symptoms

The headlamp washer nozzle on the W221 S-Class chassis is a mechanical component tied into the high-pressure washer circuit that activates alongside the windscreen washers or headlamp cleaning cycle. Failure typically presents as weak or absent spray from one or both headlamp jets, a nozzle that fails to extend/retract with the telescopic washer arm, or visible cracking and leakage around the housing. Drivers often notice water pooling under the bumper, an uneven spray pattern, or the washer pump running audibly while no fluid reaches the headlamp lens. While this component does not usually trigger a hard fault code, on some W221 variants a stuck or jammed nozzle mechanism can cause the washer pump to draw excessive current, occasionally logging a washer system malfunction in the fluid level or washer relay circuit. Corrosion at the nozzle-to-arm linkage and UV-cracked plastic housings are the most common wear points after years of service.
