Purpose and function in the BMW E90

The presented air module is a component mounted within the headliner on the left side of the vehicle, on the passenger side. It is responsible for the correct positioning and operation of the curtain airbag along the side of the cabin, working in conjunction with the factory BMW airbag system. By maintaining the original geometry and mounting points, the module allows for stable seating in the roof structure and proper integration with the headliner upholstery.

Construction and fitment to the headliner

The module has been designed as an integral part of the Headliner and parts group, meaning its shape, bracket placement, and cable routing are tailored to the factory headliner of the BMW 3 Series E90. The design provides for:

• dedicated placement on the left side of the vehicle,
• maintaining the appropriate distance from the roof lining and side pillars,
• compatibility with factory mounts and wiring harness routing.

Such a solution facilitates service work, reduces the need for modifications, and allows for the preservation of the original headliner component layout.

Benefits of using the original module

Choosing an original BMW curtain airbag module translates into a number of practical advantages in daily operation:

• Factory fitment – maintaining the correct position of the curtain relative to the pillars and side windows.
• Consistency with the safety system – the module works with the original electronics and BMW interior architecture.
• Stable installation – the manufacturer-intended mounting points minimize the risk of looseness and unwanted noises from the headliner area.

As a result, this component provides a solid foundation for post-accident repairs, replacing a damaged headliner, or restoring the car to its factory specification.

Condition and service application

The module is offered as a used part, making it an attractive cost-effective solution for bodywork repairs and interior component replacement tasks. It is particularly useful in situations where it is necessary to restore the completeness of the curtain airbag system after repairing the side of the body or replacing the headliner.

Integration with other BMW headliner components
