Purpose and fitment for BMW 3 Series E90/E90N

The presented rear left door is dedicated to the BMW 3 Series E90/E90N generation, which ensures the preservation of factory mounting points, correct geometry, and compatibility with original interior equipment and seals. Its placement at the rear on the driver's side allows for a direct replacement of the damaged component without interfering with the vehicle's body structure.

Color Black Sapphire Metallic – 475

The door is finished in Black Sapphire Metallic paint, corresponding to the factory BMW color code 475. This makes it possible to limit the scope of paint work, especially for vehicles in the same shade, which translates into time and cost savings while maintaining a consistent look for the entire bodywork.

Construction and performance parameters

The item belongs to the Doors and door panels group, meaning it has been designed as a load-bearing part of the side body structure, responsible for proper window operation, interior sealing, and stable hinge mounting. The weight of the part specified in the technical data helps maintain the proper balance of the vehicle and the correct operation of the hinges and lock, which is important for daily driving comfort.

Condition and benefits of choosing a used part

The part is offered as used, which represents a reasonable compromise between cost and functionality. Its original origin ensures dimensional compatibility with the BMW body and the ability to use existing mounting points without the need for modifications. For workshops and individual users, this means predictable installation and easier alignment with the remaining body elements.

Practical installation tips

Before installation, it is recommended to:

• verify the compatibility of the vehicle model with the E90/E90N version,
• check the condition of the hinges and lock on the car,
• compare the body lines and gaps with the existing side of the body.

This approach facilitates achieving even gaps, proper closing, and adequate acoustic and water sealing, which is important for both comfort and operational durability.
