Driver’s Seat Airbag For Citroën C4 Picasso And Grand C4 Picasso. Side Pyrotechnic Inflatable Bag. Version I.
This left front seat side airbag is an OEM-style safety module designed for Citroën C4 Picasso and Grand C4 Picasso (Version I). It provides lateral occupant protection by deploying in side-impact events to reduce thorax and pelvis injuries. The module includes a pyrotechnic inflator (squib) and soft airbag cushion integrated to fit into the seat side bolster. Ideal for mechanics and experienced DIYers who repair interior safety systems or replace deployed modules after an accident. Common search terms include part numbers 9655047480 and 8216PG, Citroën C4 Picasso airbag, left front seat airbag and seat side airbag module.
Function And Application
The seat side airbag is triggered by the vehicle’s SRS control unit during a qualifying side impact. Its role is to create a protective cushion between the occupant and door/structure, reducing the risk of rib and pelvic injuries. This module is intended for the left (driver’s) front seat on Citroën C4 Picasso I and Grand C4 Picasso I vehicles.

Replacement And Installation
Replacing a seat side airbag requires care and basic SRS safety procedures. Typical steps:
- Disconnect the negative battery terminal and wait at least 10 minutes to allow the airbag system capacitors to discharge.
- Adjust the seat to access fixation points, remove trim panels and seat covers carefully to avoid cutting or damaging the airbag housing.
- Unplug the airbag electrical connector(s) by releasing any locking tabs; avoid pulling on wires.
- Remove the mounting fasteners, replace the module with the correct part, and refit fasteners to the manufacturer’s specification.
- Reconnect the airbag connector ensuring a positive lock, reinstall trim, and reconnect the battery.
- Use a diagnostic tool to read and clear SRS fault codes and confirm the SRS warning lamp extinguishes; if the lamp remains on, diagnose the circuit before returning the vehicle to service.
Installation Recommendations
- Always follow manufacturer service procedures and torque specifications where available.
- Work in a dry, static-free environment and avoid exposing the airbag to heat, flame or impact.
- Handle the module by its housing only; do not probe the connector pins or attempt to repair the inflator.
- If uncertain about SRS diagnostics, use professional diagnostic equipment to verify system integrity after replacement.
Why This Part Most Often Fails
Seat side airbags typically fail or require replacement after deployment in a side-impact collision. Other common causes include damage to the airbag wiring or connector due to seat movement or abrasion, moisture-induced corrosion of connectors, prior improper repairs, or electrical faults in the SRS circuit. Aging alone is less commonly the direct cause of failure, but connectors and wiring can deteriorate over many years, increasing the risk of an intermittent fault.
Practical Notes For Mechanics And DIYers
Searches for this part are frequently performed using the original product numbers 9655047480 and 8216PG — include these in listings and search metadata to improve findability. Verify physical fitment by comparing mounting points and connector style before installation. After replacement, always confirm SRS system readiness with a diagnostic scanner and follow safety precautions when working on or around restraint components.
