Purpose and fitment for BMW E90

The presented component is designed as a rear left door for the BMW E90 series, maintaining factory geometry and mounting points. This ensures proper alignment with the body lines, sills, pillar, and rear fender, as well as correct compatibility with factory hinges, locks, and seals.

Placement in the Rear, Left zone ensures compatibility with the body structure, which is crucial for accident repairs, replacing corroded components, or reconstructing the side part of the bodywork. By maintaining the original structural integrity of the door, it is possible to transfer factory closing forces, ensure proper window operation, and maintain a tight seal against gaskets and moldings.

Color: Montegoblau Metallic – A51

The door is in the factory color Montegoblau Metallic – A51, characteristic of many BMW E90 configurations. The metallic paint from the manufacturer's palette allows you to:

• minimize the scope of painting when replacing the component,
• achieve a consistent visual effect with the remaining body panels,
• maintain the original character and stylistic line of the vehicle.

For body and paint shops, this means less preparatory work and easier shade matching during the restoration process.

Component characteristics and service application

As a part from the Doors and door panels group, this component serves both a structural and protective function. It is responsible for proper window operation, mounting of interior upholstery, locks, handles, and any electrical installations, as well as protecting the interior from external factors.

Doors of this type are particularly useful for:

• accident repairs of the side body section,
• removing the effects of corrosion in the lower parts of the door,
• restoring the factory appearance of the vehicle after parking damage,
• professional BMW E90 body restorations.

The used condition allows for an economical replacement of the component while maintaining the original construction and factory origin of the part.

Benefits of using original BMW doors

Using original doors in Montegoblau Metallic color brings a number of practical advantages:

• Factory fitment – preserved geometry and mounting points facilitate installation and adjustment of gaps between body elements.
• Visual consistency – the original metallic paint reduces the need for full panel painting, which shortens repair time.
• Seamless integration with equipment – the ability to transfer existing components (lock, window, wiring, upholstery) while maintaining factory functionality.
• Service solution compliant with BMW construction – the component comes from the same technological line as the other body panels, which promotes the durability of the repair.
