Purpose and vehicle placement

The presented airbag is designed for installation in the rear right door of BMW 7 Series E65/E66 vehicles. The component works with the factory airbag control unit and crash sensors, creating a cohesive side protection system for rear seat passengers.

Placement in the door means the airbag acts locally in the passenger's hip and torso area, complementing the operation of other passive safety system components. This allows for a more even distribution of forces acting on the body during a side collision.

Construction and technical compatibility

The airbag has been designed as an OEM component for a specific generation of the BMW 7 Series, which translates into precise fitment to the door structure and factory mounting points. The electrical connectors are prepared for integration with the original SRS wiring harness, which facilitates installation and reduces the risk of assembly errors.

Thanks to the use of dedicated part numbers and interchangeable numbers, the component can be used as a replacement within the configurations provided by the manufacturer, while maintaining compliance with factory safety requirements. This is a particularly beneficial solution for post-accident repairs, where both technical correctness and service economy are important.

Condition, origin, and advantages of using a used part

The airbag comes from dismantling and is offered as a used part, which allows for a significant reduction in repair costs compared to a new OEM component. At the same time, the original manufacturer's specification is maintained, including geometry, connector type, and pyrotechnic charge performance characteristics.

Choosing a used airbag for a BMW is a solution often used in professional workshops specializing in post-accident repairs of premium vehicles. With proper verification of origin and technical condition, one can achieve a favorable combination of quality, safety, and price, while maintaining consistency with the vehicle's factory safety system.

Practical installation and operational tips

Due to the nature of the component, the installation of the airbag in the rear right door of a BMW E65/E66 should be performed by a qualified service center, following safety procedures regarding pyrotechnic systems. It is crucial to:

• disconnect the vehicle's power supply before starting work on the SRS installation,
• use appropriate tools and tightening torques for fasteners,
• check the correctness of electrical connector connections,
• verify errors in the airbag control unit after installation is complete.

A properly installed door airbag restores the functionality of the passive safety system in the rear right part of the cabin, which is important both from the point of view of passenger protection and the vehicle's compliance with technical inspection requirements.
