Compatibility
Intended for Peugeot 407 series (including Saloon/Sedan, SW Estate and Coupé variants). Always verify that the left front driver-side belt corresponds to your vehicle’s configuration and mounting points before installation.
Replacement Procedure (Overview)
- Disconnect the negative battery terminal and wait at least 10 minutes to allow the SRS capacitors to discharge.
- Remove interior trim panels covering the B-pillar and lower anchor points to access mounting bolts and electrical connector for the pretensioner.
- Carefully disconnect the pretensioner electrical connector (SRS connector) and unbolt the retractor and anchor points.
- Fit the new belt ensuring correct routing of the webbing and secure all bolts to the manufacturer’s torque specifications.
- Reconnect the pretensioner connector, reassemble trim and reconnect the battery.
- Perform a diagnostic scan of the SRS system and clear any fault codes; verify that the airbag/SRS warning lamp behaves correctly.
Installation Recommendation
Work Should Be Carried Out By A Trained Technician Or A Mechanic Familiar With SRS Systems. Always Isolate The Battery Before Removing Or Installing Any Component Connected To The Supplemental Restraint System. Use Correct Tools And Torque Values From The Manufacturer’s Repair Manual. After Installation, Perform An SRS Diagnostic Check To Confirm Proper Communication With The Pretensioner Circuit. Replace Any Fasteners Or Clips That Are Damaged During Disassembly.
Why This Part Commonly Fails
- Deployment In A Collision: Pyrotechnic pretensioners Are Single-Use Devices And Must Be Replaced After Any Airbag/Seatbelt Deployment.
- Wear And Tear: Frayed Or Abraded Webbing From Prolonged Use Or Improper Routing Can Compromise Belt Integrity.
- Corrosion Or Mechanical Damage: Mounting Bolts, Retractor Mechanism Or Anchors Can Corrode Or Jam, Preventing Smooth Operation.
- Electrical/Connector Faults: Loose Or Corroded Pretensioner Connectors Can Cause SRS Fault Codes And Pretensioner Non-Function.
- Aging: Internal Retractor Components (ratchet/spring) May Gradually Degrade, Causing Locking Or Failure To Retract.
Important Safety Note: Replace The Seat Belt If The Pretensioner Has Been Activated, If The Webbing Is Damaged, Or If The Retractor Does Not Operate Smoothly. Do Not Reuse Deployed Or Damaged Components.
