Purpose and fitment for BMW 3 Series E90

The presented item is a complete rear right door designed for the BMW 3 Series E90 generation, mounted on the rear exterior of the passenger side. The construction is based on the factory BMW body geometry, which facilitates proper alignment with the fender, rocker panel, pillar, and door opening seals. As a result, after replacement, you can achieve an even gap line and stable closing of the door leaf.

Montegoblau Metallic A51 color and paint properties

The door is finished in the original Montegoblau Metallic A51 color, characteristic of selected BMW 3 Series E90 versions. The metallic paint ensures visual consistency with the rest of the body in the same color code, which facilitates matching during post-accident repairs or local body and paint corrections. The use of the factory shade limits the scope of potential blending and allows for maintaining a uniform appearance of the vehicle's side.

Structural and functional characteristics

As an element from the Doors and door panels group, the product is responsible for protecting the side of the cabin, proper window guidance, and cooperation with the lock and seals. The rear right door in the BMW E90 serves the following functions:

• load-bearing for opening and closing mechanisms,
• protective for the interior against external factors,
• structural in terms of side body rigidity.

The factory design facilitates the installation of equipment specific to a given vehicle unit, such as upholstery, lock, wiring harness, or window mechanism, without the need for modifying the door panel.

Condition, origin, and service application

The item is used, which in practice means it comes from vehicle dismantling and may show signs of wear typical for aftermarket parts. For many BMW 3 Series E90 users, this is a cost-effective service solution – it allows for reducing repair costs while maintaining the original body structure and factory color. This type of door works well both for post-accident repairs and for replacing a corroded or mechanically damaged component.

Support in selection and other BMW body parts

To facilitate identification, the product has assigned warehouse markings and manufacturer numbers, which allows for precise matching to a specific version of the BMW 3 Series E90. If necessary, you can compare the placement on the vehicle and the color with the car's factory data to minimize the risk of incorrect selection.

If you are planning a comprehensive repair or modernization of the side body zone in your BMW and need other elements from the same group, such as skins, exterior panels, or other door leaves, check the available parts in the BMW Doors and door panels category.
