Mercedes-Benz W211 W219 Windshield Washer Fluid Reservoir 2118600560 - Used Original Parts

Diagnosis and Common Symptoms

From the workshop floor, the W211 and W219 platforms commonly present with washer reservoir failures due to age-related plastic fatigue. The primary symptom is a persistent "Check Washer Fluid" or "Top Up Washer Fluid" warning on the instrument cluster, even with a full tank. This is typically caused by a faulty internal fluid level sensor. Visually, you may find fluid pooling under the front passenger-side wheel arch, indicating a crack in the reservoir body itself. In some cases, a fault code such as B1064 ("Signal from component S44 - Windshield washer fluid level indicator switch is faulty") will be stored in the SAM (Signal Acquisition Module), confirming an electrical failure of the sensor integrated into this unit.

Introduction

This is a Genuine Mercedes-Benz washer fluid reservoir, not a low-quality aftermarket copy.

We verify the integrity of the plastic by performing a leak-down test and confirm the functionality of the integrated fluid level sensor to ensure it communicates correctly with the vehicle's electronics. You are purchasing a fully operational, reliable component ready for installation.
