Hinge Rubber Mercedes W203 W204 W207 W212 Trunk Tailgate Cover Stop A2107500226

The Mercedes W203 W204 W207 W212 Tailgate Hinge Buffer is a precise component from the Tailgate and Rear Lid group, responsible for controlled closing and stable guidance of the tailgate at the rear of the body. A properly selected buffer limits unwanted play, reduces noise during closing, and supports the correct operation of the hinges on both the left and right sides.

Purpose and Technical Function

The tailgate hinge buffer in Mercedes C-Class and E-Class models is responsible for absorbing the impact of the tailgate in the final stage of closing and stabilizing its position horizontally. The component operates at the rear of the body, on the left and right sides, cooperating with the hinges and the tailgate lock.

A correctly selected buffer:

• limits tailgate vibrations during driving,
• reduces loads transferred to the hinges,
• minimizes clunks and unwanted noises from the trunk area,
• supports maintaining the correct closing geometry.

Compatibility and Fitment

The presented buffer is designed as a dedicated element for selected generations of Mercedes from the W203, W204, W207, and W212 series, which translates to factory fitment for the tailgate structure. This ensures compatibility with the original mounting point and correct cooperation with the hinges on both sides of the vehicle.

The element belongs to the group of components mounted in the rear section of the body, in the tailgate area, where precise alignment and repeatable operation with each opening and closing cycle are crucial.

Usage Characteristics of a Used Part

The buffer is a used part, meaning it is an original Mercedes component with its working geometry preserved. A used element of this class allows for economical repair of the tailgate system while maintaining factory-like parameters, without the need to resort to cheaper aftermarket alternatives with uncertain performance characteristics.

In practice, using a used buffer is particularly beneficial in situations where:

• the tailgate starts to operate with noticeable play,
• clunks appear when driving over uneven surfaces,
• correction of the closing position is necessary without interfering with the hinges.

Benefits of Correct Buffer Replacement

Replacing a worn buffer with a functional element restores acoustic comfort in the cabin and improves the subjective feel of the tailgate closing. Stable tailgate guidance also reduces long-term wear on the hinges and lock, which is important for long-term vehicle operation.

If you are planning a comprehensive repair or upgrade of the rear section of your Mercedes and need other elements from the same group, such as tailgate hinges, stops, or additional guide elements, check the available parts in the Mercedes Tailgate and Rear Lid category.

How to Sensibly Use Used Parts

For elements like the tailgate hinge buffer, using a used part is often technically justified – the component does not operate under extreme loads, and its wear can be easily assessed visually. For informed users, this means the possibility of reducing service costs while maintaining an appropriate level of safety and functionality.
