Description
Steering Wheel Airbag For Peugeot 307
This genuine steering wheel airbag is designed for the Peugeot 307 (first generation) and provides reliable driver frontal protection as part of the vehicle SRS system. The unit is an OEM-fit component originally supplied within the Stellantis group and is commonly referenced by factory part codes. It is intended for fitment into the original steering wheel hub and works together with the vehicle’s restraint system (seat belts, crash sensors and SRS control unit) to reduce injury risk in a frontal collision. Mechanics and competent DIYers will appreciate the direct-fit nature of the part and the fact that it is often searched by its product codes when sourcing replacements.
Technical Information
- Manufacturer: Stellantis / Peugeot / Citroën

Function And What To Expect
The steering wheel airbag contains the inflator (squib) and folded airbag cushion. In the event of a qualifying frontal impact, the SRS (Supplemental Restraint System) triggers the inflator to rapidly deploy the airbag, cushioning the driver’s head and chest. The airbag is not a regular wear item — it is serviceable when the original unit has deployed, if it shows SRS fault codes, or if physical or electrical damage is present.
Compatibility And Identification
This unit is intended for Peugeot 307 first-generation models. When ordering, technicians commonly use the part numbers 96556745ZR or 4112HW to confirm fitment. Always match the part code to the vehicle’s original part marking and steering wheel version to ensure correct fit and connector compatibility.
Installation Recommendations
- Always disconnect the vehicle battery and wait at least 10 minutes to allow residual charge in the SRS capacitors to dissipate before beginning work.
- Follow manufacturer procedures for airbag removal: access screws or bolts behind the steering wheel spokes (typically Torx), carefully remove the airbag module, and disconnect its electrical connector(s).
- Inspect the clock spring (spiral cable) and steering column connectors for wear or damage; replace if necessary to avoid subsequent SRS faults.
- Fit the new airbag making sure connectors are properly seated and locking tabs engaged. Refit the module to the steering wheel using the correct fasteners and tightening sequence per manufacturer guidance.
- After installation, restore battery power and use a diagnostic tool to read/clear SRS fault codes and verify correct system status. Do not ignore an SRS warning lamp — it indicates the restraint system is not ready.
- Always follow vehicle manufacturer torque values and alignment procedures for the steering wheel.
Why It Fails Most Often
- Deployment During A Collision: The most common reason for replacement is airbag deployment after an accident.
- Electrical Or Connector Issues: Damaged wiring, corroded connectors or failed squib circuits can trigger SRS faults and necessitate replacement.
- Clock Spring Failure: A worn or broken spiral cable can interrupt the airbag circuit and illuminate the SRS warning lamp.
- Physical Damage Or Moisture Ingress: Damage to the steering wheel area or moisture can degrade connections and inflator components.
Notes For Professionals
Because the airbag is a critical safety device, installation should be performed by a qualified technician or by a competent DIYer who follows official safety procedures and uses proper tools. Always verify SRS system integrity with a diagnostic tool after replacement and adhere to the vehicle manufacturer’s instructions for removal and installation.
