Description
Passenger seat airbag for Citroën C3 from 2009. Passenger seat.
High-quality replacement airbag module for the passenger seat of Citroën C3 II (A51) vehicles introduced in 2009. This part (commonly searched by part number 9802546280) restores the passive safety system after prior deployment or when the original module shows SRS faults. Designed for professional fitment but suitable for experienced DIYers who follow safety procedures, the module is intended to match the original equipment in form and function and help return the occupant protection to factory specification.
Technical Information
- Manufacturer: Stellantis / Citroën
- Model: Citroën C3 II (A51) – Passenger Seat (from 2009)
- Product Codes: 9802546280
- Additional Numbers: 9802546280
Function And Application
The passenger seat airbag is an occupant protection device mounted in the seat structure or seatback. In the event of a qualifying frontal or side collision, the airbag inflates to reduce the risk of injury to the front passenger by cushioning and controlling forward motion. The unit is part of the vehicle SRS (Supplemental Restraint System) and interfaces with crash sensors and the vehicle airbag control module.
How To Replace
- Safety First: Disconnect the vehicle battery and wait at least 3 minutes (many manufacturers recommend up to 10 minutes) to allow SRS capacitors to discharge before starting work.
- Remove Trim: Carefully remove seat trim and any covers to access the airbag fasteners and connector. Keep plastic clips intact where possible.
- Unbolt Seat Airbag: Unscrew the mounting bolts securing the airbag module to the seat frame. Support the module to avoid stressing the connector.
- Disconnect Connector: Release the airbag connector latch and remove the connector. Inspect wiring and connector for damage or corrosion.
- Install New Module: Mount the replacement airbag, torque fasteners to manufacturer specifications, and reconnect the connector ensuring a clean, secure fit.
- Reassemble And Test: Refit seat trim and reconnect the battery. Use a PSA-compatible diagnostic tool (for example DiagBox on Citroën/Peugeot vehicles) to clear SRS fault codes and confirm system readiness.
Installation Recommendations
Installation should be performed by a qualified technician or an experienced DIYer who understands SRS precautions. Always follow manufacturer torque values and wiring routing. Avoid probing airbag connectors with test equipment unless using proper isolation methods. If SRS fault codes persist after replacement, perform a full diagnostic check and address related sensors, seat occupancy mat, or wiring harness issues before returning the vehicle to service.
Why This Part Fails Most Often
Common causes of airbag module failure include prior deployment in a crash, electrical faults due to connector damage or corroded contacts (often from moisture or improper handling during seat removal), and failures in associated sensors or the seat occupancy mat that generate SRS warnings. Mechanical damage to the seat structure or wiring harness after an impact is another frequent reason the module must be replaced.
Notes For Mechanics And DIYers
This airbag is frequently searched and ordered using the part number 9802546280—listing the part number in diagnostics and parts searches speeds up identification. Replacement time typically ranges from 30 to 90 minutes depending on trim complexity and access. After installation, always verify the SRS system status with a diagnostic tool and ensure no residual fault codes remain before returning the vehicle to use.
Buying the correct airbag module and following proper installation procedures restores occupant protection and prevents persistent SRS warnings. If you are unsure about any step, seek workshop-level support to ensure safe and correct installation.
