Purpose and function in the vehicle

The presented mirror belongs to the Wing Mirrors category and is designed for installation on the left side of the BMW X3 E83 vehicle. It is responsible for direct monitoring of the side and rear zones, which is important both when changing lanes and when maneuvering in the city or in a parking lot.

The heated mirror glass supports rapid moisture evaporation and reduces frost accumulation, which translates into stable visibility during the autumn and winter season. As a result, the driver gains a more predictable field of view in changing weather conditions.

Color and matching of Montegoblau Metallic A51 paint

The Montegoblau Metallic – A51 paint is a distinctive, metallic shade of blue used by the factory in BMW vehicles. Using the original color on the mirror housing allows for visual consistency with other body elements, without the need for additional painting when the correct body version is selected.

The metallic structure of the paint coating improves light reflection and emphasizes the side lines of the BMW X3 E83, which is particularly visible in daylight and artificial light. This is a beneficial solution both for post-accident repairs and for the aesthetic replacement of a damaged mirror.

Technical characteristics and installation

The mirror has been designed as a component dedicated to a specific model, which facilitates installation in the factory door mounting points. The integrated heating is prepared to work with the vehicle's electrical system, so that after proper connection, it maintains the mirror defrosting function.

As a used part, the mirror is a practical solution for repairs where it is important to combine functionality with cost control. The original design supports proper fitment with the door line and maintains the correct geometry of the setting relative to the driver.

Practical application and user benefits

• repairs after side collisions or parking damage,
• replacing a component with a damaged heating mechanism,

Compatibility and reference numbers

The component has a dedicated OEM part number and associated interchangeable numbers, which facilitates verification of compatibility with a specific version of the BMW X3 E83.
