Key Features
- Direct fit for specified Citroën Xsara and Xsara Picasso models (pre-2003).
- Original part numbers referenced: 96447629ZL, 4112FN (NFP flagged in some records).

- Suitable For Mechanics And Competent Self-Repairers Familiar With SRS Safety Procedures.
Function
The steering wheel airbag is a key component of the Supplemental Restraint System (SRS). In the event of a qualifying frontal impact, the module rapidly inflates to help reduce driver injury by cushioning the head and chest. The airbag integrates with the vehicle crash sensors and SRS control unit to deploy only under specified conditions.
Why The Part Most Often Fails
- Deployment During A Collision: Once deployed, the airbag must be replaced — the inflator and cushion are single‑use.
- Connector Or Wiring Damage: Corroded or damaged clockspring (spiral cable) connectors can interrupt the circuit and trigger SRS faults.
- Previous Improper Handling: Incorrect removal or electrical shorting during work on the steering column can damage the module or its connectors.
- Environmental Damage: Moisture ingress or contamination in the steering column area may lead to corrosion and poor electrical contact.
Replacement Procedure (Overview)
Recommended For Experienced Technicians Or Confident DIYers With Proper Tools.
- Safety First: Always Disconnect The Negative Battery Terminal Before Starting Work And Wait At Least 10 Minutes For The SRS Capacitors To Discharge (Or Follow The Vehicle Manufacturer’s Specified Interval).
- Access: Remove Steering Column Trims To Access The Airbag Fasteners — On Many Xsara Models The Airbag Is Secured From The Rear Of The Wheel With Retaining Bolts Or Clips.
- Disconnect: Carefully Release Airbag Electrical Connectors (Clockspring/Spiral Cable Connectors). Use Appropriate Tools And Avoid Pulling On Wiring.
- Fit New Unit: Position The Replacement Airbag, Reconnect The Electrical Plugs, And Secure Fasteners To Manufacturer Specification.
- Reassembly And Checks: Refit Trim Panels, Reconnect The Battery, And Perform A Full SRS System Check With A Diagnostic Scanner To Clear Any Fault Codes And Verify Proper System Operation.
- Torque And Alignment: Ensure Steering Wheel Nut/Torque Settings And Wheel Alignment/Clock Position Are Reinstated Per Manufacturer Procedure.
Installation Recommendations
- Always Follow The Vehicle Manufacturer’s Procedures And Torque Specifications.
- Disconnect The Battery Before Demounting And Keep Terminals Isolated During Work.
- Handle The Airbag Module With Caution — Store With The Cover Facing Up And Avoid Impacting The Unit.
- Inspect The Clockspring/Spiral Cable And Steering‑Column Wiring Harness; Replace If Any Damage Or Excessive Wear Is Found.
- After Installation, Use A Compatible Diagnostic Tool To Reset SRS Faults And Confirm System Readiness.
