Product Description
This left seat airbag is a direct-fit safety module designed for the drivers seat in Citroën Xantia and Peugeot 406 vehicles. It is an original-equipment style seat side airbag intended to restore full occupant protection after deployment or damage. Frequently searched by part numbers (9647806880, 8216T8, 9450631280), this module is a practical choice for professionals and experienced DIY mechanics who maintain Stellantis group cars.
Benefits For Workshops And DIY Mechanics
Engineered to meet the demanding requirements of passive safety systems, the airbag module helps ensure correct side-impact protection and SRS performance. Clear part-number references in the listing speed up identification and procurement during repair jobs. The unit is suitable for replacement tasks where the original module has deployed, been damaged by impact, or shows electrical faults related to seat-side systems.
Function And Typical Failure Modes
The seat side airbag is part of the Supplemental Restraint System (SRS). In a side impact event the inflator rapidly deploys the airbag to protect the thorax and pelvis region. Common reasons for replacement include:
- Previous Deployment After A Crash — Deployed inflators and housings must be replaced.
- Physical Damage To The Seat Or Airbag Cover — Tears, cuts, or crushed sections can impair deployment.
- Electrical Faults Or Connector Damage — Corroded pins, broken wires or poor contacts can cause error codes and prevent deployment.
- Seat-Occupancy Sensor Or Wiring Issues — Faults in related circuits may trigger SRS warning lights leading to diagnosis and replacement of the seat module.

Installation Recommendations
Proper installation of SRS components is critical for safety. Follow these recommendations:
- Always Disconnect The Battery First And Wait At Least 10 Minutes Before Working On The Airbag System To Allow The SRS Capacitors To Discharge.
- Follow The Vehicle Manufacturers Procedure For Seat Removal And Refit. Remove Trim Panels Carefully To Avoid Damaging Airbag Covers.
- Disconnect The Airbag Connector Using The Correct Release Method; Do Not Pull On Wiring.
- Replace Any Damaged Clips Or Wiring Looms. Use Correct OEM Fasteners And Tightening Values As Specified By The Manufacturer.
- After Mechanical Fitment, Clear Related Fault Codes With A Suitable Diagnostic Tool And Verify SRS System Status. Do Not Use Simple Test Lights Or Incorrect Electrical Test Methods On Airbag Circuits.
- If You Are Not Confident With SRS Work, Have The Replacement Performed By A Qualified Technician Experienced With Airbag Systems.
Reason This Part Fails Most Often
The predominant cause of seat airbag replacement is prior deployment in a collision. Secondary causes include connector corrosion or wiring damage (often from moisture ingress or seat removal), and physical damage to the airbag cover from wear or impact. Electrical faults in related seat systems can also lead to SRS warning lights and diagnosis that requires module replacement.
Notes For Ordering
Customers commonly search using the OEM part numbers listed above. Verify the numbers printed on the existing module before ordering to ensure compatibility with the Citroën Xantia or Peugeot 406 application. This listing is aimed at mechanics and experienced DIYers familiar with SRS procedures.
