Purpose and vehicle placement

The presented wiper arm is designed for installation on the right side (driver's side) in Mercedes W219 and W211 class vehicles. It is responsible for the proper guidance of the blade across the windshield surface, maintaining the factory range of motion and wiper system kinematics. Thanks to its correct profile and fitment to the mechanism arm mount, the component works seamlessly with the original drive, minimizing vibration and noise during operation.

Technical and functional characteristics

The wiper arm is an OEM construction part, which means it maintains factory parameters for length, angle, and blade mounting point. This configuration allows for:

• maintaining the correct windshield cleaning area on the driver's side,
• even pressure of the blade against the glass along its entire length,
• proper cooperation with the wiper mechanism and tension spring,
• stable operation across a wide range of driving speeds.

By maintaining the original geometry, the arm does not cause excessive wear on the blades or the windshield, and the wiper system operates in a predictable and repeatable manner, in accordance with the vehicle manufacturer's specifications.

Condition of the item and benefits of use

The offered wiper arm is a used component, which in practice represents a favorable compromise between purchase cost and the preservation of original manufacturing quality. Compared to low-budget replacements, the original arm provides better fitment to the mount, proper rigidity, and adequate resistance to deformation during wiper operation. This solution is particularly recommended for repairs where maintaining the factory parameters of the windshield cleaning system is crucial.

Selection by numbers and compatibility verification

The wiper arm has a dedicated OEM part number and associated replacement numbers, which facilitates precise identification and selection for a specific vehicle configuration. Before purchasing, it is worth comparing the markings with the existing component or service documentation to ensure full compatibility with the specific Mercedes W219 or W211 unit.
