Compatibility And Fitment
Intended for Peugeot 407 saloon and estate (SW) body styles equipped with roof-side curtain airbags. Fits the passenger (right) side roof rail. Verify the part numbers against the vehicle’s existing module before installation; many technicians locate this part by its OEM code 9660989280 or the reference 8331AC.
Installation Recommendations
Work On Airbag Systems Should Be Performed With Care. Before starting, isolate the vehicle electrical system by disconnecting the negative battery terminal and waiting at least 10 minutes to allow SRS capacitors to discharge. Remove necessary trim and headliner panels to access the roof-rail airbag module. Unbolt the module mounting points, carefully disconnect the airbag connector and any retaining clips, and replace with the new unit. Refit trim and secure all fasteners to the manufacturer’s specified torque values. After installation, use an SRS diagnostic tool to confirm correct wiring, clear fault codes and ensure the airbag indicator behaves normally. If in doubt, have the final checks performed by a qualified technician.
Why This Part Most Often Fails
Curtain airbags Are Typically Replaced After Deployment Following A Collision. Other common causes of failure or removal include prior accident repairs where the airbag or its wiring was damaged, water ingress from roof or door seals leading to connector corrosion, and physical damage during interior work. Electrical faults such as broken wiring, corroded connectors or failed inflator mechanisms can trigger SRS warning lights and necessitate replacement. Regular inspection after collisions or when SRS faults appear will help identify issues early.
For workshops and self-repairers, choosing the correct OEM-referenced airbag (9660989280 / 8331AC) ensures proper fit and restore of side-impact protection on the passenger side of the Peugeot 407.
