Description
Product Overview
The left roof airbag designed for Citroën C8 and Peugeot 807 is a driver-side Supplemental Restraint System (SRS) module mounted in the roof lining above the door. It inflates within milliseconds during a qualifying impact to protect the head and upper torso, helping reduce injury risk in side and rollover collisions. Technicians and DIYers frequently search by part number, so this unit is listed as 1400418980 / 8329SG for quick identification.
Benefits And Application
This airbag is an OEM-fit replacement intended to restore the vehicle’s original passive safety after deployment or module failure. It is suitable for workshops and competent self-repairers who follow correct SRS procedures and use proper diagnostic equipment to verify system status after installation.
Common Failure Modes
- Deployment in a collision (airbags are single-use safety devices).
- Electrical faults such as damaged or corroded connectors that trigger SRS warning lights.
- Water ingress, roof liner damage, or improper previous repairs affecting module function.
Installation Notes
Airbag replacement requires care and adherence to SRS safety protocols. Typical replacement steps are:
- Disconnect the negative battery terminal and wait at least 10 minutes to allow residual charge to dissipate (follow vehicle manufacturer recommendations).
- Remove roof trim and headliner panels as needed to access the airbag module and mounting hardware.
- Carefully unplug the SRS connector and remove the mounting bolts holding the module in place.
- Fit the new module in the correct orientation, secure it with the specified torque, and reconnect the SRS connector securely.
- Reinstall trim, reconnect the battery, and clear SRS codes using a compatible diagnostic tool. Verify system readiness and that no fault codes remain.
While experienced DIYers can perform this replacement, it is recommended to confirm correct function with a diagnostic scanner and consult a professional technician if any SRS faults persist.
