Description
Right pyrotechnic seatbelt pretensioner for Citroën C2, C3 and C3 Pluriel. Passenger seat.
This replacement pyrotechnic seatbelt pretensioner is designed for the right (passenger) side of Citroën C2, C3 and C3 Pluriel models. The pretensioner tightens the seatbelt immediately during a collision to reduce occupant movement and improve airbag effectiveness. It carries OE reference numbers commonly used when searching for direct-fit parts, making it suitable for professional workshops and competent DIY mechanics who maintain or repair occupant restraint systems.

Function And Notes
The pyrotechnic pretensioner is a one‑shot safety device that activates in a crash to remove slack from the belt webbing. After deployment the pretensioner must be replaced. The unit contains an initiator charge and electrical connector; it is part of the vehicle’s supplemental restraint system (SRS) and must be handled with care.
Replacement And Fitment
Fitment is usually direct to the vehicle’s existing seatbelt anchoring points. Depending on equipment level and build date, the pretensioner may be integrated in the retractor assembly or attached to the buckle/anchor. Typical replacement steps for an experienced technician or competent DIYer:
- Isolate the vehicle electrical system: disconnect the negative battery terminal and wait the manufacturer‑recommended time for SRS capacitors to discharge (commonly 10–15 minutes).
- Remove necessary trim panels to access the pretensioner mounting and connector.
- Unplug the SRS electrical connector and unbolt the pretensioner from its mount.
- Install the new pretensioner in correct orientation, torque fasteners to manufacturer specifications and reconnect the SRS connector.
- Reassemble trim panels, reconnect the battery and verify SRS warning lamp behaviour per manufacturer procedure.
Installation Recommendations
Always follow manufacturer procedures and torque settings when working on the restraint system. Wear appropriate personal protective equipment. Do not attempt to recondition or tamper with the initiator charge. After fitting, perform an SRS system check with proper diagnostic equipment to confirm fault codes are cleared and the airbag warning lamp operates normally. If any doubt exists about the diagnosis or coding, have the work carried out or verified by a qualified technician.
Most Common Causes Of Failure
Pretensioners typically become non‑functional after deployment in a collision. Other common reasons for replacement include electrical connector damage, corrosion from water ingress, physical impact to mounting points during vehicle repair, or wiring harness faults. Age alone rarely triggers deployment, but environmental damage and accidents are the primary causes of failure.
Why Choose This Part
This part lists the OE reference numbers used by Stellantis and matches the applications shown above, making it a practical choice for technicians searching by part number. Replace pretensioners with correct application parts to preserve occupant protection and compliance with safety standards.
Important Safety Reminder
Disconnect the battery before removal or installation and follow the vehicle manufacturer’s safety procedures to avoid accidental activation or damage to the restraint system.
