Purpose and function in the vehicle

The roof curtain airbag mounted in the headliner on the right side is responsible for protecting the head and upper torso of passengers during side impacts and selected rollover scenarios. The element is an integral part of the passive safety system of the Audi A4 B9 generation, working in conjunction with collision sensors and the airbag control unit.

Thanks to its factory geometry and mounting points, the curtain adapts to the shape of the pillars and roof edges, which allows for maintaining the correct deployment zone of the airbag at the moment of activation. The appropriate design of the pyrotechnic charge and gas channels ensures predictable inflation in accordance with the manufacturer's specifications.

Construction and mounting compatibility

The element belongs to the Headliner and parts group, which means it is structurally adapted for installation in the upper part of the cabin, along the roof edge on the passenger side. The applied mounts, wiring harness routing, and electrical connector comply with factory Audi standards, which facilitates installation in place of the original curtain without the need for modifications.

The placement on the right side of the vehicle is important both in terms of safety and proper fitment to the interior trim. Proper positioning relative to the headliner, pillars, and door seals is crucial for the correct deployment of the airbag during system activation.

Condition, verification, and selection by part numbers

The product is offered as a used OEM element, which in practice means maintaining the factory construction and operating parameters while optimizing repair costs. Before installation, it is recommended to perform a standard verification of the SRS installation in the vehicle, including checking for errors in the control unit and inspecting the wiring harness and connectors.

To select the correct curtain for a specific version of the Audi A4 B9, it is worth using the part number and interchangeable numbers assigned to this component. Detailed markings can be found in the technical specifications section, which facilitates matching to the model year, body version, and equipment configuration.

Benefits of using an original Audi curtain

Using an original roof curtain in the Audi A4 B9 ensures:

• maintenance of factory side protection parameters for passengers,
• secure fitment to the headliner construction and body pillars,
• cooperation with the existing SRS system controller and sensors,
• consistency with other passive safety elements in the vehicle.

Thanks to this, a post-collision repair or replacement of a damaged curtain can be carried out in a technically correct manner, maintaining the manufacturer's assumptions regarding the protection of vehicle users.
