Fitment And Application
Fits the left (driver side) roof-mounted side curtain location on Peugeot 407 saloon and estate versions. Check the part numbers 966098980 or 8331AE when searching for compatibility in parts catalogs or during ordering. This airbag replaces the factory-fitted curtain module in the roof lining.
Function
The curtain airbag deploys in significant side impacts to reduce the risk of head injury by cushioning and separating the occupant from side structures and intruding objects. It also helps reduce injuries during rollovers by providing coverage along the window/roof rail area.
Replacement Procedure
- Always work with the vehicle battery disconnected. Follow the manufacturer waiting period after disconnecting the battery to ensure the SRS capacitors discharge.
- Remove interior trim and headliner clips carefully to access the curtain airbag module and retain all fasteners for reuse or replacement as required.
- Disconnect the airbag electrical connector(s) and remove mounting bolts or clips securing the module to the roof rail.
- Install the replacement module in the reverse order: secure fasteners to the correct torque, connect electrical connector(s) firmly, and refit trim and headliner ensuring correct seating of clips and seals.
- After installation, restore battery power and use a diagnostic tool to check the SRS system, clear any stored fault codes and verify that the airbag warning lamp functions correctly.
Installation Recommendations
- Handle the airbag module as a safety device: store it away from heat sources and static-sensitive areas, and avoid impact to the inflator.
- Observe anti-static precautions and do not probe connectors with power applied.
- Use appropriate trim tools to avoid damaging interior panels and clips. Replace any broken clips or damaged trim pieces.
- If SRS fault codes remain after installation, diagnose and repair wiring, connectors or control modules before returning the vehicle to service.
- For safety-critical procedures and SRS diagnostics, consider professional installation if you are not fully experienced with airbag systems.
Why This Part Most Commonly Fails
Curtain airbags do not have a scheduled service life and only require replacement after deployment. Common reasons for replacement or failure include previous deployment in a collision, physical damage from intrusion, water ingress or roof damage, corrosion or broken connectors, and incorrect prior repairs. If the SRS warning lamp is illuminated and diagnostic trouble codes point to the curtain circuit, inspect connectors and wiring harness routing before replacing the module.
