Other Numbers: E 00 (as referenced in supplier listings)
Function And Fitment
The actuator operates the central locking mechanism in the left rear door, converting electrical signals from the vehicle’s central locking system into mechanical movement that locks or unlocks the door latch. It is intended for fitment to the left rear door of Peugeot 407 models. The unit connects to the vehicle wiring harness via a multi-pin connector and mounts directly to the door lock assembly.
How The Part Is Replaced
- Remove the interior door trim panel and any trim clips carefully to avoid damage.
- Peel back the water/sound insulation membrane to access the lock assembly.
- Disconnect the actuator electrical connector and any linkages connected to the latch.
- Unscrew the mounting bolts securing the actuator to the door latch and remove the faulty unit.
- Install the replacement actuator, reconnect linkages and electrical connector, and test locking/unlocking before reassembling the door trim.
- Reattach the insulation and trim panel, ensuring all clips and screws are secure.
Typical workshop time for replacement: approximately 30–60 minutes depending on experience and vehicle equipment.
Installation Recommendations
- Work on a cool, dry car and disconnect the battery if you will be handling exposed connectors for an extended time.
- Inspect harness connectors for corrosion or broken pins; clean and apply dielectric grease to prevent future corrosion.
- Check the door latch mechanism and linkages for wear or bent rods; replace or adjust as needed for smooth operation.
- Test the actuator operation with the door open before refitting the trim to confirm proper function.
Why This Part Commonly Fails
Actuators most often fail due to water ingress and corrosion, worn electric motor brushes, or broken plastic gears inside the mechanism. Frequent use, exposure to moisture over time and mechanical strain from misaligned latch components accelerate wear. Symptoms include intermittent locking, slow or noisy operation, or complete loss of locking function on the affected door.
Additional Notes For Buyers
When searching or ordering, customers often use the OEM numbers 9660699280, 9137K8 or 9137Q7—include these codes in your search to find the correct part. Suitable for Peugeot 407 left rear door replacement; verify physical match against the existing actuator during installation (mounting points and connector type).
