Purpose and Function in the Washer System

The heated hose with windshield washer nozzle in the Mercedes W212 is responsible for precise fluid dispensing onto the windshield and maintaining system flow at low temperatures. This component operates within the category Washer Fluid Tanks, Pumps, and Nozzles, working in conjunction with the vehicle's pump, tank, and electrical system. A properly functioning heated nozzle reduces the risk of fluid freezing in critical sections of the hose, leading to better visibility and stable wiper operation.

Construction and Key Technical Features

The offered component combines a fluid supply hose and a heated spray nozzle in one housing. The OEM solution ensures:

• factory fit for the washer system in Mercedes W212,
• manufacturer-designed fluid spray pattern for the windshield,
• integrated heating circuit compatible with the vehicle's electrical system,
• stable mounting in factory body points.

This ensures predictable installation and that the washer system's operating parameters remain consistent with the vehicle manufacturer's specifications.

Benefits of Using an Original Mercedes Part

Using an original heated windshield washer nozzle helps avoid common problems associated with aftermarket parts, such as incorrect spray angles, uneven fluid streams, or limited durability of heating elements. The main advantages include:

• Compatibility with the Electrical System – the load and parameters of the heater are adapted to the installation in the Mercedes W212.
• Stable Winter Operation – reduced freezing of fluid in the hose and nozzle, making it easier to maintain windshield clarity.
• Replication of Factory Spray Pattern – proper windshield coverage with fluid, without dead zones or excessive fluid consumption.
• Consistency with Other System Components – the hose and nozzle work with the original washer tank and pump.

Condition, Installation, and Service Application

The component is offered as a used part, providing a cost-effective service solution for users seeking original components at a reasonable price. Before installation, a standard visual inspection of connectors, the hose, and the nozzle socket is recommended, as well as verification of the heating circuit's correct operation after installation in the vehicle. Replacing this component is a typical service operation in case of nozzle damage, hose leaks, or problems with washer heating.
