Description
Steering wheel airbag for PEUGEOT 307
This steering wheel airbag is a direct-fit replacement designed for Peugeot 307 vehicles. Suitable for professional mechanics and experienced DIYers, the unit is commonly searched by reference numbers 96556746ZR and 4112HW. It restores the driver-side Supplemental Restraint System (SRS) functionality after deployment or electrical failure and is an important safety component of the vehicle interior.
Function And Application
The driver airbag is a pyrotechnic safety device integrated into the steering wheel hub. In the event of a qualifying collision, the squib ignites and the bag inflates to reduce head and chest injuries. The module contains the airbag cushion, inflator/squib, and an electrical connector to the vehicle SRS wiring. It is intended for Peugeot 307 models and is compatible with steering wheels factory‑fitted for the driver airbag.
Technical Information
- Manufacturer: Stellantis / Peugeot
- Model: Peugeot 307 (First Generation)
- Product Codes: 96556746ZR, 4112HW

Installation Recommendations
- Disconnect the vehicle battery and wait at least 10–15 minutes before starting work to allow SRS capacitors to discharge.
- Follow the vehicle manufacturer’s removal sequence: access the airbag fasteners (usually from the rear of the steering wheel), remove the module, and carefully disconnect the electrical connectors.
- Avoid pulling on wires or damaging the clock spring (spiral cable). If the clock spring is damaged, replace it together with the airbag.
- Reinstall by reversing the removal steps. Tighten steering wheel and airbag fasteners to the manufacturer’s torque specifications and reconnect the battery only after the unit is secured.
- After installation, clear SRS fault codes and verify the airbag warning light using an appropriate diagnostic tool. If the warning lamp remains on, further diagnosis of the SRS system is required.
- Do not attempt to disassemble or repair the airbag module; replace with a complete unit if faulty or after deployment.
Why The Part Most Commonly Fails
- Deployment During A Collision: Airbags are single‑use devices and must be replaced after activation.
- Electrical Faults: Corroded connectors, damaged wiring or a defective squib can cause SRS faults and airbag failure.
- Physical Damage: Steering wheel impacts, previous repairs, or improper handling during maintenance can damage the module.
- Environmental Factors: Moisture ingress or prolonged exposure to contaminants can compromise connectors and internal components.
