Product Overview

Right-side passenger seat airbag designed for Peugeot 307 models (first generation). This SRS seat module is commonly searched by part numbers 5110819, 8216L2 and 8216FH. It replaces the seat-mounted airbag module located in the passenger seat and restores occupant protection after deployment or when the original unit is faulty. Wiring harnesses and connectors are sometimes sold separately, so delivery may not include the seat wiring loom.

Key Benefits

• Direct-fit replacement for compatible Peugeot 307 seat assemblies.
• Maintains factory safety function when installed and coded correctly.
• Commonly available under multiple product codes (see Technical Information).
• Suitable for professional fitters and experienced DIY enthusiasts with SRS knowledge.

Installation Recommendations

Airbag replacement must be handled with care. Follow these general steps and always adhere to the vehicle manufacturer’s service manual:

• Disconnect the negative battery terminal and wait at least 10 minutes to allow the SRS capacitors to discharge.
• Remove seat trim and any covers to access the seat airbag module fixing points.
• Unbolt the airbag module carefully and disconnect the connector(s). Note locking tabs and orientation.
• Install the replacement module, ensuring correct connector engagement and secure fastening of mounting bolts.
• Reassemble trim and reconnect the battery. Use an appropriate diagnostic tool to read and clear SRS fault codes and verify system readiness.
• If wiring is not supplied, inspect the vehicle harness and connectors for damage; replace or repair as required before completing installation.

Why The Part Most Commonly Fails

• Deployment In An Accident: Airbags are single-use devices and must be replaced after deployment.
• Electrical Damage: Damaged squib wiring or connector faults can generate SRS errors or render the module inoperative.
• Corrosion And Water Ingress: Moisture in the seat area can corrode connectors and cause intermittent or permanent faults.
• Physical Damage Or Seat Repair: Repairs to the seat structure or improper handling during removal/installation can damage the airbag or its wiring.
• Age-Related Degradation: While airbags do not have a routine replacement interval, connectors and harness insulation can degrade over many years.

Additional Information For Fitters

This part is intended for professional fitters and experienced DIY mechanics. Always verify part numbers against the vehicle’s original equipment references and inspect the seat wiring and connectors prior to installation. If the vehicle shows SRS warning lamp faults after replacement, a dedicated diagnostic tool should be used to identify and clear codes.

Safety Notice

Do not attempt to repair deployed airbag modules. Always follow safety procedures when working with SRS components: disconnect the battery, wait the recommended time, and avoid contact with the squib connector pins. Improper handling can cause injury or unintended deployment.

Product Overview

High-quality passenger seat airbag module designed for Peugeot 307 vehicles. This airbag assembly is intended to replace a deployed or faulty passenger seat airbag to restore occupant protection and fault-free operation of the restraint system. The airbag does not include the seat wiring harness or connectors; these must be reused from the original vehicle or ordered separately.

Function And Application

The seat airbag inflates during a qualifying frontal or offset collision to protect the front passenger by reducing head and chest impact forces. It is a passive safety component integrated into the passenger seat structure or seatback, depending on the vehicle variant. Correct installation and secure electrical connections are essential for proper deployment and SRS system integrity.

How It Is Replaced

• Disconnect the vehicle battery and wait at least the time recommended by the manufacturer (typically 10–15 minutes) to allow the SRS capacitors to discharge.
• Remove the seat trim and any seat covers to access the airbag module fixing points.
• Unbolt the airbag module from the seat frame according to the manufacturer procedure and carefully disconnect the airbag connector(s).
• Transfer any required trim pieces or mounting hardware to the replacement module if they are not supplied.
• Install the new airbag by reversing removal steps, secure fasteners to the manufacturer torque, reconnect the battery, and clear SRS fault codes with diagnostic equipment if necessary.

Installation Recommendations

• Always Disconnect The Battery Before Any Work On The SRS System And Observe Manufacturer Safety Intervals.
• Handle The Airbag Module With The Trim Side Facing Up And Do Not Place Affected Side On A Hard Surface.
• Use Appropriate ESD/anti-static Precautions When Working Near Airbag Connectors And Control Units.
• After Installation, Use A Diagnostic Tool To Verify SRS System Status And Clear Any Fault Codes.
• Follow Repair Manual Instructions For Fastener Torque And Connector Locking Procedures.

Why The Part Most Often Fails

Seat airbags typically require replacement after deployment in a crash. Additional causes of failure include water ingress, physical damage from seat impacts or heavy loads, connector corrosion, or improper previous repairs. Fault codes from the SRS control unit will often indicate an open or short circuit on the airbag squib circuit when the module is faulty.
