The product has a dedicated OEM part number and assigned replacement numbers, which facilitates verification of compatibility with specific equipment versions. When selecting, it is advisable to compare the markings with the currently installed component to ensure full compatibility with your specific BMW model.

Condition, Origin, and Benefits of Using a Used Part

The seat belt buckle is a salvaged part offered as an original BMW part in used condition. This means it retains the factory construction, materials, and operating parameters intended by the vehicle manufacturer. In practice, this translates to:

• consistency with the factory safety system – no need for adaptations or modifications to mounting points,
• preservation of original ergonomics – correct positioning of the buckle relative to the seat and backrest,
• favorable cost-to-functionality ratio – ability to restore full seat belt system functionality without investing in expensive aftermarket parts.

For many users, choosing a used OEM part is a sensible compromise between quality and budget, especially for older vehicle generations like the BMW E39.

Installation and Usage Aspects

The rear center seat belt buckle is intended for installation in the rear of the vehicle at the factory mounting point. When replacing, it is recommended to:

• check the condition of screws and mountings – if necessary, use new fasteners in accordance with manufacturer recommendations,
• verify the correct operation of the latching mechanism after installation – buckle and unbuckle the belt multiple times,
• check the seat belt routing relative to the seat and backrest to avoid twisting the webbing.

A properly installed buckle ensures secure belt fastening, user comfort, and predictable safety system behavior in everyday use.
