Description
Left front pyrotechnic seatbelt for Citroën C1 and Peugeot 107. For vehicles manufactured up to 2013. Driver’s seat. 5-door.
This left front pyrotechnic seatbelt (driver’s side) is a direct-fit safety component designed for Citroën C1 and Peugeot 107 5-door models produced up to 2013. The unit combines a conventional retractor with an integrated pyrotechnic pretensioner that activates in a collision to remove slack and improve occupant restraint together with the airbag system. Ideal for professional workshops and experienced DIY mechanics looking for a reliable OEM-compatible replacement, the part is frequently searched for by its product codes—include these when ordering to ensure compatibility.
How It Works
The pyrotechnic pretensioner contains a small pyrotechnic charge that, when triggered by the vehicle’s SRS control unit during a crash, rapidly tensions the belt webbing to secure the occupant. After deployment the pretensioner and belt must be replaced. The retractor mechanism also locks under sudden deceleration to restrain movement.
How To Replace
Basic replacement steps (for qualified technicians or experienced DIYers):
- Park vehicle on level ground, engage handbrake.
- Disconnect the negative battery terminal and wait at least 10 minutes (follow manufacturer recommendations) to allow the SRS capacitors to discharge.
- Remove seat trim and covers to access the belt retractor and anchor bolts.
- Disconnect the pretensioner electrical connector carefully.
- Unbolt the retractor and lower anchor, remove the old belt assembly.
- Install the new belt assembly, reconnect the electrical connector, and secure all bolts to the manufacturer’s torque specification.
- Reinstall trim, reconnect the battery, and verify SRS system status with a diagnostic tool; clear any fault codes if present.
Installation Recommendations
- Always disconnect the battery and follow the vehicle manufacturer’s prescribed waiting time before working on SRS components.
- Do not attempt to repair or reuse a pretensioner once deployed; replace with a new unit.
- Use correct tools and torque settings specified by Citroën/Peugeot for seatbelt and anchor bolts.
- After fitting, check the airbag/SRS system with a diagnostic scanner and clear any related fault codes; if warning lamp persists, diagnose with a professional tool.
- If electrical connectors are corroded or damaged, renew them to ensure reliable signal transmission to the SRS ECU.
Why This Part Fails Most Often
Pyrotechnic seatbelts typically fail or require replacement for the following reasons:
- Deployment During A Collision: The pretensioner is single-use and must be replaced after activation.
- Electrical Faults Or Damaged Wiring: Faulty connectors or wiring can prevent the pretensioner from arming or trigger SRS faults.
- Corrosion Or Contamination: Moisture ingress or corrosion at connectors or mounting points can degrade function.
- Mechanical Damage: Damage during accident, improper seat removal, or rough handling can impair the retractor or webbing.
- Age And Wear: Although durable, belts and retractors can wear over many years; inspect periodically for fraying or impaired locking.
