Purpose and fitment for BMW E90

The presented rear door is designed specifically for installation on the rear left side of the BMW E90 series body. Proper positioning on the vehicle ensures correct alignment with the fender, rocker panel, pillar, and lock, which translates into proper operation of the hinges, lock, and seals, as well as stable closing of the door panel.

Montegoblau Metallic A51 color

The factory Montegoblau Metallic A51 color is a distinctive, metallic shade of blue used by BMW, which emphasizes the side line of the body and works well with both chrome and black trim elements. Using a door in the same color allows for reducing the scope of paint work, facilitates visual matching, and helps maintain a consistent look for the entire side of the vehicle after repair.

Structural characteristics of the door

The door belongs to the Doors and door panels category, meaning it is a structural element of the side body, responsible for proper window operation, mounting of upholstery, lock, hinges, and seals. OEM construction ensures:

• preservation of factory hinge and lock mounting points,
• correct edge geometry relative to the fender and rocker panel,
• compatibility with original seals and trim strips,
• the ability to transfer equipment from the vehicle's previous door.

Condition of the component and use in repairs

The component comes from a used vehicle, making it an attractive solution for accident repairs, corrosion corrections, or replacing damaged doors while keeping costs reasonable. A used OEM component allows for maintaining compliance with the vehicle's factory specifications while reducing the time needed for fitting and preparation for installation compared to aftermarket body parts.
