Description
Left front seat airbag for Peugeot 308 T7. Driver side.
This driver-side seat airbag is intended for Peugeot 308 (T7) vehicles and is a direct-fit replacement for the left/front seat airbag module. It restores side-impact protection for the driver seat and is a commonly required part after an airbag deployment or when the SRS system reports a related fault. Keywords: Peugeot 308 airbag, driver seat airbag, seat airbag module, Peugeot 308 T7 airbag.
Function and Application
The seat side airbag inflates instantly in the event of a qualifying side impact to reduce risk of thorax and pelvis injuries. The module is integrated into the side of the seat (seatback or seat bolster, depending on trim) and works as part of the vehicle’s Supplemental Restraint System (SRS). It is designed to operate together with crash sensors and the airbag control unit to provide occupant protection during a collision.
Typical Replacement Procedure
Replacing a seat airbag requires care and adherence to safety procedures. Typical steps for replacement:
- Disconnect the vehicle battery and wait at least 10 minutes to allow SRS capacitors to discharge (follow manufacturer guidance for exact wait time).
- Remove seat trim panels and any seat covers to access the airbag module mounting points.
- Unplug the airbag electrical connector(s) by releasing the safety locking tab—do not pull on wires.
- Unscrew the module from the seat structure and fit the replacement in the same orientation; secure fasteners to the original torque where specified by the manufacturer.
- Reconnect the connector ensuring the locking mechanism is fully engaged and reassemble seat trim.
- Reconnect the battery and clear SRS fault codes with a suitable diagnostic tool; verify system status and SRS lamp extinguishes.
Installation Recommendations
Work on airbag systems should be performed by a trained technician or a competent DIYer who understands SRS safety rules. Always disconnect the battery before starting and follow the vehicle manufacturer’s service procedures. Use appropriate tools and a diagnostic scanner to clear fault codes and confirm proper system operation after replacement. Inspect the seat wiring harness and connector for corrosion or damage and replace any compromised components. Never attempt to repair an airbag inflator or wiring; replace the entire module if damaged.

Why This Part Fails Most Often
The most frequent reasons for seat airbag replacement are deployment during a collision and physical damage to the module or wiring. Other common causes include connector corrosion, damaged seat mechanisms that chafe wiring, and SRS faults triggered by prior improper repairs or poor electrical connections. Airbags are designed to remain functional for the life of the vehicle but must be replaced after deployment or when the SRS indicates a fault affecting airbag readiness.
Notes For Mechanics and DIYers
This part is intended for professional installation or experienced DIY maintenance. After installation, confirm successful communication with the airbag control unit and clear any stored fault codes using PSA-capable diagnostic equipment where available. Proper installation ensures occupant safety and prevents persistent SRS warnings on the instrument cluster.
