Description
Clock Spring (Airbag, Horn) – Rotary Contact. For CITROËN C1 and PEUGEOT 107 vehicles. Up To Model Year 2012.
This used steering column clock spring (spiral cable) is designed to restore electrical continuity between the steering wheel and the vehicle wiring for airbag, horn and steering wheel controls on Citroën C1 and Peugeot 107 models (up to 2012). Ideal for professional workshops and experienced DIY mechanics searching by part number 4112HX.
Product Overview
The clock spring (also known as a spiral cable or rotary contact) provides a reliable rotating electrical connection that allows the driver’s airbag, horn and steering wheel switches to remain connected while the wheel is turned. Common symptoms of a faulty unit include persistent airbag warning lamp, non-functional horn, or loss of buttons on the steering wheel. Replacing a worn or damaged clock spring typically resolves these issues.

Installation Recommendations
Follow a safe, methodical procedure when replacing the clock spring. If you are not experienced with airbag systems, have the work performed by a qualified technician.
- Disconnect The Battery: Always isolate the battery and wait the manufacturer-recommended time before starting to prevent accidental airbag deployment.
- Remove Airbag Module: Carefully remove the driver airbag following the vehicle manufacturer’s procedure and store it facing upward in a secure area.
- Mark Steering Wheel Position: Centre the steering wheel and mark its position relative to the steering column to ensure correct reinstallation.
- Remove Steering Wheel: Unfasten and remove the steering wheel to access the clock spring.
- Replace Clock Spring: Unplug electrical connectors, remove the old clock spring and install the new unit making sure it is centered (neutral position) before tightening.
- Reassemble And Torque To Spec: Refit the steering wheel and airbag, torque fasteners to the manufacturer’s specification and reconnect the battery as the last step.
- Verify Functionality: Check Airbag Lamp, Horn, And Steering Wheel Controls After Installation.
Why This Part Fails Most Often
Clock springs typically fail due to internal ribbon cable wear or breakage caused by repeated full-angle steering movements over time. Common causes include friction and abrasion of the flat flex cable, incorrect installation (misalignment or installing in a non-centred position), or damage during steering column repairs. Signs of failure are intermittent or permanent loss of horn function, inoperative steering wheel buttons, and an illuminated airbag warning light.
Additional Notes For Mechanics
When sourcing parts by code, use the product code 4112HX to speed up identification. There Is No Fixed Replacement Interval — Replace On Failure Or After Airbag Deployment. Handle All Airbag Components With Care And Follow Safety Precautions.
