Description
Left Front Upper Seat Airbag For Peugeot 308 CC. Driver Side.
This driver-side left front upper seat airbag is a direct-fit safety component designed for Peugeot 308 CC models. Intended for professional workshops and skilled DIY mechanics, this part restores occupant protection after airbag deployment or damage. Frequently searched by OE numbers 9684113780 and 8216WY, the unit fits into the seatback top section and integrates with the vehicle’s SRS wiring and connectors.
Function And Application
The seat airbag is a supplemental restraint device mounted in the seatback to provide additional lateral protection for the driver during certain side impact events. It works together with door and curtain airbags and the vehicle’s airbag control module to help reduce the risk of injury. This part is specifically intended for Peugeot 308 CC models and replaces the factory-installed left front upper seat airbag.
How Replacement Is Performed
- Disconnect the negative battery terminal and wait at least 10 minutes (or follow manufacturer-specified interval) to allow the SRS system capacitors to discharge.
- Remove seat trim and upholstery panels carefully to access the airbag module retaining points. Keep trim clips and screws organized for reassembly.
- Unbolt the airbag module from the seat frame and disconnect the airbag connector(s). Note connector orientation and locking tabs.
- Install the replacement airbag in the correct orientation, reconnect the locking connector(s), and secure the module to the seat frame with the original fasteners using the correct torque where specified.
- Reattach seat trim and upholstery, reconnect the battery, and verify SRS system status with a diagnostic tool. Clear fault codes if required and confirm the SRS warning lamp extinguishes after system checks.
Mounting Recommendations
- Always Disconnect The Battery Before Work: Prevent accidental deployment by isolating the vehicle electrical system and waiting the recommended time.
- Observe Static Precautions: Avoid impact, compression, or exposure of the airbag inflator to heat or sparks during handling.
- Use Correct Fasteners And Torque Values: Reuse original bolts where possible and follow manufacturer torque specifications to ensure secure mounting.
- Check Connector Locking Mechanisms: Ensure SRS connectors are fully engaged and locking tabs are intact to avoid intermittent faults.
- Final System Check With Diagnostic Tool: Verify SRS status and clear codes using an appropriate diagnostic device after installation.
Why The Part Most Commonly Fails
Seat airbags generally do not fail in normal service life but require replacement after deployment in a collision. Other common causes for replacement include physical damage to the module or seat (for example from impact or improper repairs), water ingress or corrosion of connectors, wiring damage or chafing in the seat harness, and improper previous installations. Faults in the SRS circuit or damaged connector pins can also trigger airbag warnings and necessitate replacement.
Recommended Replacement Interval
There Is No Routine Service Interval For Airbags; Replace After Deployment Or If The Module/Connectors Are Physically Damaged Or Show Electrical Faults. Any SRS Warning Lamp Indication Requires Diagnostic Investigation And Rectification.
