Purpose and fitment for BMW 3 Series E90 / E90N LCi

The presented rear left door is dedicated to the BMW 3 Series E90 and E90N facelift (LCi) generations, ensuring compatibility with the factory body construction of these versions. The placement on the vehicle is the rear zone on the driver's side, making this part the right choice for repairing the side bodywork after a collision or due to corrosion.

The original BMW origin guarantees the preservation of correct hinge, lock, and seal mounting points, which translates into proper alignment with the rocker panel, pillars, and roofline. This is particularly important for premium-class cars, where assembly accuracy affects not only aesthetics but also interior acoustics and body sealing.

Montegoblau Metallic color – A51 and the benefits of a pre-painted finish

The door is factory-painted in the Montegoblau Metallic – A51 shade, characteristic of many BMW 3 Series units of this generation. Using the original metallic paint reduces the scope of paintwork required – in many cases, simply matching the shade and light polishing is sufficient instead of painting the entire component from scratch.

For the user, this means:

• shorter body repair time,
• reduced paintwork costs,
• easier maintenance of color consistency across the entire side of the vehicle.

The metallic Montegoblau paint harmonizes well with the E90 design line, emphasizing the dynamic character of the body and maintaining the car's original appearance after repair.

Construction, function, and application in the door zone

The door belongs to the Doors and door panels category, meaning it is a key structural element of the side body. It is responsible for proper window guidance, interaction with seals, and correct closing and locking of the latch. The original construction ensures compatibility with factory fittings, wiring harnesses, handles, and other components mounted in the door.

A used body component is a good solution in situations where:

• mechanical damage to the door has occurred as a result of a collision,
• advanced corrosion appears on the edges and the lower part of the panel,
• it is necessary to replace the entire panel instead of performing local bodywork repairs.

Choosing an original BMW door allows you to maintain the factory panel gaps, which is important both visually and technically.

Used condition and the advantages of using OEM parts

The door is offered in used condition, which enables an optimal combination of quality and reasonable repair costs. The original OEM part retains the proper structural rigidity and is designed according to the manufacturer's safety standards. Compared to aftermarket body parts, factory doors usually work better with existing body elements, which facilitates the adjustment of hinges and locks.

For body shops and private users, this means:

• easier alignment of the component during assembly,
• lower risk of problems with closing and adjustment,
• preservation of the original characteristics of the BMW 3 Series body.
