Function And Application
The roof (curtain) airbag deploys in side impacts and certain rollover events to protect the head and upper torso of the occupants. Installed along the roof rail, the left roof airbag shields the driver’s side windows and pillars, reducing the risk of head injury during lateral collisions.
How The Part Is Replaced
- Disconnect the negative battery terminal and wait at least 10–15 minutes to allow SRS capacitors to discharge.
- Carefully remove the relevant interior trim: A‑pillar trim, roof lining edge covers and fasteners to access the airbag housing. Keep trim clips and fasteners for reinstallation.
- Unbolt the airbag module from the roof rail (typically 1–3 Torx/hex fasteners depending on model year) and disconnect the electrical connector(s). Note the connector orientation and any locking tabs.
- Fit the replacement module in the original position, secure fasteners to the manufacturer’s torque where available, and reconnect the electrical connector ensuring the locking mechanism engages.
- Reinstall trim panels in reverse order. Reconnect the battery.
- Use a diagnostic tool to read and clear SRS fault codes. Verify System Status: confirm no residual airbag faults and perform SRS readiness checks.
Installation Recommendations
- Always Disconnect The Battery Before Work: Remove negative terminal and wait the recommended time to avoid accidental deployment.
- Follow Manufacturer Procedures: Use correct fasteners, torque settings and trim removal techniques to avoid damaging clips, wiring or the roof lining.
- Use A Diagnostic Scanner: After installation clear SRS fault codes and confirm system integrity with a capable diagnostic tool (workshop grade scanner recommended).
- Handle Pyrotechnic Components With Care: Do not strike, heat or expose the airbag inflator to impact. Store flat and away from strong electrical sources.
Why This Part Fails Most Often
The left roof airbag is most commonly replaced after deployment in an accident. Other frequent causes of failure or removal include electrical faults (damaged connectors or wiring), water ingress causing connector corrosion, or physical damage from interior work/incorrect disassembly. Age and long‑term exposure to humidity can contribute to connector degradation and unreliable deployment signals.
Notes For Professionals And DIYers
Intended For Experienced Technicians And Competent DIY Mechanics: Airbag systems are safety‑critical. If you are not confident in SRS procedures, seek professional installation. After replacement, always verify SRS readiness using a diagnostic tool and follow Peugeot safety guidelines.
Search Tip: This part is frequently looked up by OE numbers 9676859780 and 8338U8—use these codes when searching catalogs or ordering to ensure you receive the correct left roof airbag for Peugeot 308 first series.
