Vehicle Application and Function

The presented door airbag is a component of the side safety system, activated in the event of an impact to the vehicle's side. Mounted in the right front door, it works in conjunction with collision sensors and the SRS control unit, forming a cohesive protection system for the driver or front right passenger. The airbag's design has been specifically developed for the door architecture of the BMW E38 and E39, ensuring stable mounting and predictable performance upon deployment.

Compatibility and Service Fitment

The airbag is designed as an OEM part for specific generations of the BMW 5 and 7 Series, meaning it is compatible with factory mounting points and the original electrical harness. The component has an assigned part number and interchangeable numbers, which facilitates verification of compatibility with a specific vehicle configuration in service catalogs. This allows a mechanic or diagnostician to select the correct airbag for a given year and equipment version in a controlled manner, minimizing the risk of incorrect selection.

Technical Characteristics and Installation

The front right door airbag is structurally adapted to operate within the confined space inside the door panel. The module's shape, mounting point locations, and electrical connector have been optimized for:

• proper airbag deployment upon activation,
• interference-free operation with the window and lock mechanisms,
• maintaining seal integrity and stability over long-term use.

During installation, it is crucial to follow manufacturer procedures, including disconnecting power, proper handling of the airbag connector, and checking for errors in the SRS control unit after completing the work. Using an original module allows for maintaining the integrity of the safety system with the vehicle's factory settings.

Condition, Origin, and Practical Application

The offered airbag is a used part, sourced from disassembly, making it an attractive cost-effective solution for vehicle repairs where restoring full SRS system functionality is required after a collision or replacement of damaged doors. Such components are frequently used in professional workshops specializing in the BMW brand, where both adherence to factory specifications and cost-effective servicing are important.
