Description
Complete AFIL unit assembly, seat vibration for Citroën C5 and other models
This AFIL seat vibration module is designed to provide tactile lane-departure alerts (AFIL – Alerte Franchissement Involontaire de Ligne) for compatible Citroën and Peugeot vehicles. Supplied with the manufacturer part code 8906CJ, the unit restores the haptic warning function built into the driver’s seat, improving safety by delivering clear vibration pulses that help the driver notice unintentional lane drift without adding extra audible alerts. Ideal for professional workshops and experienced DIY mechanics who service Stellantis vehicles.
Key Benefits
– Restores AFIL seat vibration feedback for safer driving and improved lane-departure awareness.
– Direct-fit part for vehicles using part number 8906CJ (see Technical Information for compatibility notes).
– Compact, robust design intended to integrate with the existing seat structure and wiring harness.

Compatibility And Fitment
This AFIL seat vibration assembly fits vehicles from the Stellantis group that use the 8906CJ part code. Common fitment includes Citroën C5 variants equipped with the AFIL system; some Peugeot and other Citroën models may share the same part depending on factory options and build configuration. When searching, technicians commonly reference the part number 8906CJ to locate the exact unit.
How The Part Is Replaced
Replacement is straightforward for a competent technician or experienced DIYer with basic tools. Typical procedure:
- Disconnect the vehicle battery before any work to avoid electrical shorts and to protect occupant restraint systems.
- Move the seat to its rearmost/foremost position to access fixings; remove lower trim panels as required.
- Unplug the seat wiring harness connectors that supply the AFIL unit (note connector retention clips) and unbolt the module from the seat frame.
- Install the new unit in reverse order, ensuring connectors are fully seated and trim panels are refitted securely.
- Reconnect the battery and verify AFIL seat vibration operation through a road test or the vehicle’s onboard diagnostics where applicable.
Installation Recommendations
- Always Disconnect The Battery: Remove the negative terminal and wait a few minutes before working on seat electronics to reduce risk of airbag faults.
- Use Correct Tools: Avoid forcing connectors or trim; plastic clips are fragile after years of service.
- Check Wiring And Connectors: Inspect harnesses for corrosion, chafing, or damaged pins and repair before fitting the new unit.
- Test Functionality: After installation, confirm the AFIL vibration activates under test conditions and that no related fault codes remain in the vehicle control units.
- If In Doubt, Use A Workshop Manual: Follow the vehicle manufacturer’s seat removal and refit procedures to avoid damaging seat mechanisms or occupant safety systems.
Most Common Failure Causes
- Connector Corrosion Or Poor Contact: Moisture ingress or long-term oxidation can interrupt power or signal to the vibrator motor.
- Electrical Faults: Short circuits, damaged wiring or failed solder joints inside the module can stop the unit from operating.
- Mechanical Wear: The vibration motor or its mounting can deteriorate over many years of use, reducing effectiveness or causing noise.
- Impact Or Water Damage: Seat floods, heavy spills or collision forces can damage the unit or its connectors.
- Intermittent Problems After Seat Removal: Improper reconnection of harnesses or incorrectly routed cables during reassembly can create faults.
Service Life And Expectations
There is no strict replacement interval; many AFIL seat vibration units last the lifetime of the vehicle. Failures are more commonly observed in older cars, vehicles exposed to moisture, or after seat removal/accident repairs. If the seat no longer provides haptic alerts or fault codes appear related to AFIL, replacing the vibration assembly with the correct part number (8906CJ) is a common repair.
Notes For Workshops And DIY Mechanics
Search engines and technicians often look up this part by code 8906CJ, AFIL seat vibration, or Citroën C5 seat buzzer/module. Include these keywords in inventory and repair records to speed up future sourcing. Follow safe working practices when handling seat electronics and occupant safety systems.
