The part is commonly referenced by its product codes and is suitable for professional workshops and experienced DIY mechanics who perform SRS repairs and seat disassembly.
Function And Fitment

How Replacement Is Carried Out
Basic replacement steps (overview):
- Disconnect the negative battery terminal and wait at least 10 minutes to allow the SRS capacitor to discharge.
- Remove seat trim and upholstery carefully to access the airbag module. Keep trim clips and fasteners organized.
- Unplug the airbag connector(s) using a proper locking-release technique. Avoid pulling on wiring.
- Remove retaining screws or clips securing the airbag module and extract the unit from the seat.
- Install the replacement airbag in the correct orientation, secure fasteners to the manufacturer’s specification, and reconnect the electrical connector.
- Reinstall seat covers and trim, reconnect the battery, and perform an SRS system scan with a diagnostic tool to confirm fault clearance and system readiness.
Installation Recommendations
- Always follow Manufacturer Procedures. If in doubt, have the replacement carried out by a qualified technician.
- Disconnect the battery before any work on the SRS system. Wait at least 10 minutes after disconnecting before touching airbag connectors.
- Handle the airbag module with care: store it facing upward and away from heat sources and static discharge.
- Do not use damaged connectors or harnesses. Repair or replace damaged wiring before reinstallation.
- After installation, verify the SRS system with a suitable diagnostic scanner and clear any stored fault codes. If the airbag warning lamp remains on, further diagnosis is required before the vehicle is returned to service.
Most Common Causes Of Failure
- Deployment In A Prior Collision — Airbags Must Be Replaced After Deployment.
- Connector Or Wiring Damage — Chafing, Corrosion, Or Loose Pins Can Interrupt Circuit Continuity.
- Water Ingress Or Seat Moisture — Prolonged Exposure Can Cause Electrical Faults.
- Improper Repairs Or Improper Reassembly — Poorly Secured Modules Or Damaged Clips Affect Function.
- Manufacturing Age Or Environmental Stress — Insulation And Connectors May Degrade Over Many Years.
Notes
No scheduled replacement interval exists for airbag modules; replacement is required after deployment or when the SRS system reports a fault related to the seat airbag. Always use the correct part codes (9684113780 / 8216WY) to ensure proper compatibility with the Peugeot 308 CC seating assembly.
