Purpose and fitment for the BMW 3 E90

The offered item is a complete rear passenger-side door, designed specifically for the BMW 3 Series E90 body. The construction is compatible with factory hinge, lock, and seal mounting points, which facilitates installation and reduces the need for additional bodywork modifications. The characteristic body lines and side profile of this model are preserved, ensuring a seamless connection with the fender, rocker panel, and pillar after installation.

Montegoblau Metallic A51 color – repair benefits

The door is factory-painted in the Montegoblau Metallic A51 shade, which is significant for post-accident repairs and visual corrections. Using a component with the same paint code often allows for limiting the scope of painting to minimal touch-ups, which shortens repair time and reduces costs. The metallic structure of the coating is consistent with BMW's color line, making it easier for a painter to blend adjacent panels if necessary.

Technical characteristics and installation

The rear right door for the BMW E90 is structurally prepared to work with the model's factory components – hinges, lock, door wiring harness, and window. Thanks to the preservation of the original geometry, it is possible to correctly set the gaps between body panels and ensure the proper operation of the lock and seals. This is particularly important for maintaining cabin airtightness, proper closing, and reducing wind noise while driving.

As a used part, this item is a good choice for body shops and individual users looking for an economical solution that is simultaneously compliant with BMW factory specifications. Replacing the entire door is often faster and more predictable than extensive repair of a heavily damaged panel.

Practical application and repair scenarios

The rear right door in Montegoblau Metallic is particularly suitable in situations where:

• there has been side damage in the rear passenger-side door area,
• it is necessary to replace a corroded or deformed panel,
• preserving the original body line and factory fitment is a priority,
• optimizing repair costs while maintaining OEM quality is important.

Because this is an original BMW component, compatibility with factory seals, trim, and hardware is maintained, which facilitates the transfer of equipment from the previous door.
