Description
Left roof-mounted side airbag for PEUGEOT 407 saloon and estate. Driver side.
This left roof-side airbag is a direct-fit replacement for the driver-side roof lining on the Peugeot 407 saloon (sedan) and estate (SW). It provides side-impact and rollover protection by deploying from the roof rail to reduce head and thorax injuries. The part is frequently identified by product numbers 966098980 and 8331AE, so many mechanics and DIYers search using these codes when sourcing a replacement.

Installation Recommendations
Installation should be performed by a trained technician or an experienced DIYer familiar with SRS systems. Follow these steps and safety rules:
- Disconnect the negative battery terminal and wait at least 3 minutes to allow the airbag system capacitors to discharge.
- Work with the ignition off and avoid static discharge near the airbag module.
- Carefully remove the roof lining trim panels to access the airbag; avoid damaging trim clips and harnesses.
- Unplug the airbag connector using the locking mechanism; do not pull on wires.
- Remove mounting fasteners, fit the replacement module, and secure fasteners to the manufacturer’s torque specification.
- Reattach connectors ensuring positive locking, refit trim, reconnect the battery, and clear SRS fault codes with an appropriate diagnostic tool.
- Verify Correct Operation: Confirm that the airbag warning lamp extinguishes after codes are cleared and the system completes its self-check.
Common Failure Reasons
- Deployment In A Collision: The most obvious cause—if deployed, the module must be replaced.
- Electrical Faults Or Connector Corrosion: Moisture ingress or corroded contacts can interrupt the circuit and trigger SRS errors.
- Water Ingress Through Sunroof Or Door Seals: Persistent leaks may damage the module or wiring inside the roof area.
- Damage During Previous Repairs: Incorrect trim removal or rough handling can break connectors or the inflator mechanism.
- Sensor Or Wiring Faults Elsewhere In SRS System: Faults may present as a bad airbag module when the root cause is a damaged sensor or harness.
Typical Fitment Note: This item is suitable for Peugeot 407 models produced in the 2004–2011 range (saloon and estate) for the driver-side roof position. Searching by code 966098980 or 8331AE will help locate the correct replacement for workshop use or self-repair projects.
