Description
Clock spring under steering wheel (airbag, horn) – rotary contact. For CITROËN C1 and PEUGEOT 107 vehicles. Up to model year 2012.
Product Overview
Replacement clock spring (spiral cable / contact ring) for Citroën C1 and Peugeot 107 (up to 2012), often referenced under code 4112HX. This rotary contact transmits electrical signals between the vehicle body and the steering wheel while allowing continuous wheel rotation. It carries circuits for the driver airbag, horn and, where fitted, steering wheel controls.
Key Benefits
- Restores Reliable Airbag And Horn Functionality: Ensures continuous electrical connection for safety and signalling systems.
- Direct Fit For C1 / 107 Models Up To 2012: Designed to match factory mounting and connector types for straightforward replacement.
- Commonly Searched By Part Code: Many mechanics and DIYers find this part by code 4112HX.
Installation Recommendations
Always follow safe working procedures when replacing a clock spring. Recommended steps:
- Disconnect The Battery And Wait At Least 10 Minutes To Allow Airbag Capacitors To Discharge.
- Center The Steering Wheel And Mark The Steering Column Position To Preserve Alignment.
- Remove The Driver Airbag Module Carefully (Follow Manufacturer Safety Instructions).
- Remove The Steering Wheel Following Manufacturer Torque And Removal Procedures.
- Unplug The Old Clock Spring Connectors And Remove The Unit From The Column.
- Fit The New Clock Spring In The Neutral (Centered) Position — Do Not Rotate The Unit Before Installation.
