Description
Side roof airbag for CITROEN C3 vehicles from 2009. Driver’s side.
Product Overview
This left (driver’s side) side roof airbag (side curtain) is a direct-fit safety component for Citroën C3 II (A51) models introduced from 2009. Designed to protect occupants during side impacts and rollovers, the unit sits in the roof rail above the door opening and deploys almost instantly when the SRS control unit detects a qualifying event. Ideal for professional workshops and experienced DIY mechanics who repair collision damage or restore SRS functionality.
Key Features & Function
– Side curtain design protects head and upper torso of front and rear occupants during lateral impacts and rollovers.
– Located along the roof rail and integrated with the vehicle’s SRS wiring and sensors.
– Deploys based on signals from side impact sensors and the central SRS control unit.
– Direct OE fitment when using the correct product codes listed below.
Replacement Procedure (How To Replace)
Only for trained technicians or experienced DIYers with appropriate safety knowledge. Basic replacement steps:
- Disconnect the negative battery terminal and wait at least 10 minutes to allow SRS capacitors to discharge.
- Remove interior trim pieces and headliner fasteners to access the roof rail area (start with grab handles, A‑pillar trims and roof-lining fixings).
- Carefully unclip or unbolt the airbag retaining brackets; avoid excessive bending or flexing of the airbag housing.
- Disconnect the airbag electrical connector(s) using appropriate SRS-safe tools; do not apply power to the connector when exposed.
- Install the replacement unit in reverse order, ensuring correct routing of wiring and secure mechanical fastening.
- Reassemble trims and reconnect the battery. Use an appropriate diagnostic tool to read and clear SRS fault codes; confirm system readiness and perform any required calibrations.
Installation Recommendations
– Always Disconnect The Battery Before Work And Observe Manufacturer Procedures To Prevent Damage And Unintended Deployment.
– Use Genuine Or Correct OE-Equivalent Fasteners And Clips To Preserve Fitment And Safety.
– After Replacement, Clear And Verify SRS Fault Codes With A Professional Diagnostic Tool; Some SRS Faults Require Specialist Equipment To Reset.
– If In Doubt, Have The Job Performed Or Checked By A Workshop Experienced With Citroën SRS Systems.
Most Common Failure Causes
– Deployment During A Collision: Once Deployed, The Airbag Must Be Replaced.
– Connector Damage Or Corrosion: Moisture Or Damage During Previous Repairs Can Cause Intermittent Faults.
– Physical Damage To The Roof Lining Or Rail (From Previous Accidents Or Poor Repair Work) That Affects Airbag Mounting.
– Faults In Associated Sensors Or Wiring Harness Resulting In SRS Warning Light Activation.
