Over time, wiring harnesses can degrade due to various factors, including wear and tear, exposure to moisture, and electrical issues. It’s vital to replace faulty or damaged wiring to maintain the effectiveness of your seat belts, which are essential during collision events.

When replacing the wiring harness, it is advisable to follow the manufacturer’s guidelines to ensure a proper fit and functionality. Regular inspection of the seat belt system is recommended to prevent failures and enhance passenger safety.

Technical Information

Product Codes: 8978FP
Additional Numbers: NFP

Function: The pyrotechnic pretensioner contains a small pyrotechnic charge that, when commanded by the airbag control unit during a collision, fires and rapidly retracts the belt webbing to remove slack. This action reduces occupant movement and improves the effectiveness of the restraint system in the initial milliseconds of an impact.

When To Replace: Replacement is normally required after airbag deployment, if the airbag/SRS warning lamp is illuminated with stored pretensioner faults, or when the retractor or connector shows visible damage. Common failure causes on older PSA vehicles include corrosion, damaged or loose connectors beneath the seat, or internal activation of the pyrotechnic charge.

Fitment And Checks: Confirm compatibility by matching the OEM code 8972S2 and by comparing the mounting points, connector shape and lock/pretensioner location with the original unit. This pretensioner is intended for the right front position (passenger side on left-hand drive vehicles) and is controlled by the vehicle’s airbag control module.

Installation Notes (General Guidance):

• Always disconnect the negative battery terminal and wait several minutes to allow SRS capacitors to discharge before working on the restraint system. Work in an electrostatic-safe environment.
• Move the seat to its rearmost or forward-most position as required to access fasteners, remove seat mounting bolts and carefully disconnect electrical connectors under the seat (airbag/pretensioner).
• Replace the pretensioner assembly as a complete unit following the vehicle manufacturer’s service manual; check wiring and connector condition and secure all fastenings to the specified torque.
• After installation, reconnect the battery and use a diagnostic tool to clear airbag fault codes and verify the SRS system status.

Typical symptoms that indicate pretensioner issues: persistent airbag warning lamp, stored pretensioner fault codes in the airbag control unit, locked or rough seat belt retractor operation, or visible damage to the belt/connector. Always verify exact fitment and safety compatibility before installation.

This is a driver-side pyrotechnic seatbelt pretensioner (pyro-pretensioner) with OEM code 8972WQ, intended for Citroën Xsara and Peugeot 306 vehicles. The unit instantly tightens the lap/shoulder belt during a collision to reduce webbing slack and improve occupant restraint. Supplied as an original PSA part, functionally checked during dismantling and offered as a cost-effective replacement for SRS/seatbelt repairs.

Function

In the event of a crash the airbag control unit sends a trigger signal to the pyrotechnic pretensioner. The small pyrotechnic charge activates and retracts the belt webbing toward the occupant, reducing forward movement and improving the effectiveness of the restraint system. The pretensioner works in conjunction with airbags to improve crash outcome.

Symptoms Of Failure

Common signs that a pretensioner is faulty include an illuminated airbag (SRS) warning lamp, stored SRS fault codes, or noticeably reduced belt tightening on the driver side. Pretensioners most often require replacement after deployment in a collision; they can also fail from corrosion, moisture ingress, wiring or connector faults, or age-related degradation.

Installation Recommendations

Always disconnect the vehicle battery and wait a minimum of 10 minutes to allow airbag system capacitors to discharge before any work. Do not probe or measure the pretensioner connector with a multimeter. Fit the pretensioner in the correct orientation for left/driver side and tighten mounting fasteners to the torque values specified in the manufacturer’s service documentation. After installation clear SRS fault codes with a diagnostic tool and confirm system status. Verify connector type and pin alignment before final assembly.

Compatibility & Verification

This pretensioner is intended for selected versions of Citroën Xsara and Peugeot 306. Compatibility can vary by trim level, body style (3/5‑door, sedan, estate) and production variant. Before ordering, compare the OEM number on your original unit (label on the belt or pretensioner), check connector shape and mounting orientation, or verify by VIN to ensure a correct match.

Condition

Original PSA part removed from dismantling and functionally checked during disassembly. The unit may show normal signs of use consistent with its age but is supplied as a serviceable replacement. The marking NFP indicates the new original part is no longer in production (No Further Production), making this genuine used unit a suitable substitute for repairs.
