Description
Left driver airbag for steering wheel for Citroën C1 model years 2012–2013.
Product Overview
This left driver airbag unit (Steering Wheel Airbag) is intended for Citroën C1 vehicles produced in model years 2012–2013. Supplied with reference numbers commonly used in parts catalogues, the module is suitable for professional workshops and experienced DIY mechanics replacing a deployed or defective driver airbag assembly. The module contains the inflator/squib and the cover assembly matched to the left (driver) position in the steering wheel.
Features And Function
- Primary safety component of the Supplemental Restraint System (SRS) that deploys in a qualifying frontal impact to protect the driver.
- Includes inflator (gas generator) and squib electrical connector that is wired through the steering column clock spring (spiral cable).
- Designed to work together with seat belts, crash sensors and the vehicle SRS control unit to meet the intended occupant protection function.
Replacement Procedure (How It Is Exchanged)
Replacing a driver airbag requires careful adherence to safety procedures and correct handling of pyrotechnic components. Typical replacement steps:
- Park vehicle on level ground, put transmission in park (or neutral) and apply parking brake.
- Disconnect the negative battery terminal and wait at least 10 minutes to allow the SRS system capacitors to discharge.
- Remove steering wheel trim/horn pad retaining clips or screws following manufacturer trim removal procedure.
- Carefully release the airbag module retaining bolts and disconnect the airbag electrical connector(s) from the squib. Label connectors if needed.
- If steering wheel removal is required, mark steering wheel and shaft alignment, loosen the central nut, remove wheel, ensure clock spring remains centered.
- Fit replacement airbag, reconnect squib connector(s), torque retaining fasteners to manufacturer specification and reassemble trim.
- Reconnect battery, test SRS system with an appropriate diagnostic tool and confirm no fault codes or SRS warning light. Clear faults only after repairs are complete.
Installation Recommendations
- Always disconnect the battery and follow the vehicle manufacturer procedure to avoid accidental deployment and component damage.
- Ensure the clock spring (spiral cable) is correctly centered before reinstallation. Incorrect clock spring position can cause airbag faults or loss of steering wheel electronic functions.
- Use correct torque values for steering wheel and airbag fasteners as specified in the workshop manual.
- Inspect connectors and wiring for corrosion or damage; replace damaged connectors or wiring harness sections before reassembly.
- After installation, verify SRS system status with an airbag-capable diagnostic tool and confirm the SRS warning lamp extinguishes after engine start and self-test.
- Handle the module with the trim cover facing away from the body and store/transport following safety rules for pyrotechnic devices.
Common Failure Causes
- Deployment During A Collision — The most frequent reason for replacement is airbag deployment after an accident.
- Clock Spring (Spiral Cable) Wear Or Damage — Loss of electrical continuity through the steering column can trigger SRS faults and prevent deployment.
- Connector Corrosion Or Wiring Damage — Moisture ingress or mechanical damage at connectors can cause open/short circuits in the squib circuit.
- Previous Incorrect Repair Or Tampering — Improper handling after deployment or poor-quality repairs can leave the system inoperative.
- Electrical Faults In SRS Network — Faulty sensor inputs or control unit errors may indicate airbag-related faults though the underlying cause can be elsewhere in the SRS system.

Notes For Professionals And DIYers
This airbag is a safety-critical component. While an experienced technician or competent DIY mechanic can perform the replacement, it must be carried out carefully with correct tools and diagnostics. After replacement, confirm system integrity by reading and clearing SRS fault codes and performing the vehicle self-test. Always follow local regulations for disposal of deployed modules and handling of pyrotechnic safety devices.
