Function And Fitment

The seat-mounted driver airbag cushions and protects the torso and pelvis in side impacts and certain collisions. It is mounted inside the left-side driver seat (seatback/cushion area depending on the variant) and integrates with the vehicle SRS (Supplemental Restraint System). This unit is intended for Peugeot 407 models; verify correct part code match before installation. If the original airbag has been deployed, damaged, or triggers an SRS warning light, replacement is required to restore full system functionality.

Recommended Installation

• Disconnect the negative battery terminal and wait at least 10 minutes to allow SRS capacitors to discharge.
• Remove seat trim and covers carefully to avoid tearing cloth/leather and damaging clips.
• Unbolt the airbag module from the seat frame using hand tools; avoid impact tools that can damage the unit.
• Disconnect the airbag electrical connector by releasing locking tabs—do not pull on wires.
• Install the replacement airbag in reverse order. Use manufacturer torque values for seat and airbag fasteners (refer to the workshop manual).
• After installation, reconnect the battery and use an appropriate diagnostic tool to check and clear SRS fault codes. Confirm that the airbag warning lamp behaves normally during key-on self-test.
• Handle and store the airbag with the pad facing upward and avoid exposure to heat sources, sparks or static discharge.

Most Common Failure Causes

• Deployment In A Collision: Airbags are single-use; any deployed airbag must be replaced.
• Electrical Damage Or Corrosion: Moisture ingress, connector corrosion, or damaged wiring can cause SRS faults and loss of function.
• Connector Or Harness Damage During Seat Removal: Rough handling when removing seats or interior trim can damage the airbag connector or wiring.
• Mechanical Damage: Seat impact, excessive wear, or improper repairs can impair module mounting or inflate performance.
• Faults Detected By SRS Control Unit: Sensor or module faults logged by the SRS control unit will illuminate the airbag warning light and necessitate diagnosis and possible replacement.

Replacing the airbag should be performed by qualified technicians or experienced DIYers who follow SRS safety procedures and have access to the vehicle workshop manual and diagnostic equipment. Proper installation ensures reliable operation and passenger protection in the event of an accident.

This airbag is tailored for the Peugeot 407 model, making it an ideal replacement part for both professional mechanics and experienced DIY enthusiasts. Installation is straightforward, requiring careful disconnection of the battery and proper handling of the connector cables to ensure full functionality and safety compliance.

Fitment

Fits Peugeot 407 models from the 2004–2011 production period where factory equipment includes a driver’s seat side airbag. Compatibility depends on seat type and original part number; verify that the original airbag part number matches 96625550ZD before installation.

Function

The seat-mounted side airbag protects the torso and pelvis in a side impact by deploying between the occupant and the intruding structure. It is a single-use safety device: if deployed in a collision, it must be replaced. Proper function depends on intact wiring, connectors, and seat mounting.

Replacement Procedure

• Disconnect the negative battery terminal and wait at least 10 minutes to allow capacitors in the restraint system to discharge.
• Move the seat to an accessible position. Remove seat trim panels carefully to access the airbag module retaining screws or bolts.
• Disconnect the airbag electrical connector (typically yellow) by releasing the locking tab; do not pull on wiring.
• Remove fasteners and extract the old airbag module from the seat. Fit the replacement in the correct orientation and secure with the original fasteners.
• Reconnect the airbag connector ensuring a positive lock. Reinstall seat trims and reconnect the battery.
• Clear any fault codes with appropriate diagnostic equipment and confirm SRS system reports no active faults.

Installation Recommendations

• Always disconnect the battery before starting work and follow the vehicle manufacturer’s safety instructions.
• Observe electrostatic discharge (ESD) precautions when handling airbag modules and connectors.
• Do not use excessive force or probe airbag connectors with test equipment while connected to the vehicle.
• Replace any damaged clips, fasteners, or seat trim items to ensure correct fitment and deployment path.
• After installation, use a diagnostic tool capable of reading the SRS system to confirm correct functionality and to clear fault codes.
• When in doubt, have the final check and code clearing performed by a qualified technician with appropriate diagnostic equipment.

Most Common Failure Reasons

• Deployment in a previous collision — airbags are single-use and must be replaced after deployment.
• Damaged or corroded connectors and wiring due to moisture ingress or seat removal/repair.
• Incorrect repairs or aftermarket modifications to the seat compromise the airbag system.
• Mechanical damage to the airbag module caused during vehicle disassembly or interior work.

Notes

Replace the airbag only with a correct part matching the original part number. Do not attempt repairs on an airbag module. Follow all safety procedures to avoid accidental deployment and injury.
