Purpose and compatibility for BMW E90

The presented rear left door has been designed specifically for the BMW 3 Series E90 body structure. Proper positioning on the rear left side of the vehicle ensures correct alignment with the rocker panel, pillar, and rear fender, which is crucial for both body geometry and proper door closing.

As a component from the Doors and door panels category, this part serves as a structural base for windows, seals, locks, and upholstery, allowing for the transfer of existing equipment from damaged doors without the need to interfere with the body structure.

Montegoblau Metallic - A51 color and paint aspects

The factory Montegoblau Metallic - A51 color is a distinctive metallic blue shade used by BMW, which effectively highlights the side profile of the body. Using the correct paint code facilitates:

• reducing the scope of potential blending on adjacent panels,
• maintaining visual consistency with other body panels,
• speeding up the preparation process for painting or polishing.

As a result, the door can be used both in post-accident repairs and vehicle restoration, where color compatibility with the rest of the body is essential.

Structural characteristics and performance parameters

The rear left door for the BMW E90 serves as a load-bearing element for opening mechanisms, window guides, and seals, and also influences the rigidity of the side of the body. The properly selected weight of the structure promotes the maintenance of the vehicle's correct balance and the proper operation of hinges and the lock.

As a used component, the product allows for economical vehicle repair while maintaining original geometry and door operating characteristics. In practice, this means the ability to restore proper closing, correct seal adhesion, and appropriate alignment of gaps between body elements.

Technical markings and interchangeable numbers

The door has a dedicated OEM part number and associated interchangeable numbers, which facilitates verification of compatibility with a specific equipment version and model year of the BMW E90. This allows for precise selection of the component for your vehicle, minimizing the risk of mismatch in terms of construction, mounts, or body lines.

The presence of multiple reference numbers is particularly important for workshops and service centers specializing in the BMW brand, where quick identification of parts and the ability to compare with manufacturer catalogs are valued.

Condition, application, and benefits of installation

As an aftermarket component, the rear left door for the BMW E90 is a practical solution for body repairs where combining reasonable costs with maintaining the original body structure is key. This type of part will work well both in professional service centers and in independent workshops carrying out post-accident repairs and vehicle reconstructions.

The main benefits of using this component include:

• the ability to use existing sub-assemblies (windows, lock, wiring, upholstery),
• maintaining the factory side line of the BMW body,
• easier preparation for painting thanks to the matching paint code.
