Description
Tailgate handle for CITROEN C4 and C5 II. External opener control for the tailgate. Microswitch tested and functional. Colour EYL – PAINT GREY ICELAND.
Overview
Replacement exterior tailgate handle designed for Citroën C4 and Citroën C5 II models. This handle houses the opening mechanism and an integrated microswitch that signals the locking/central locking system when the tailgate is operated. Supplied in EYL Grey (Iceland) paint finish and identified by product codes 9649858777 and 8726Q8, this part matches the original exterior appearance and connection points for direct fit on compatible vehicles.
Key Benefits
- Direct fit for correct alignment and operation with factory mounting points.
- Integrated microswitch already tested and verified as functional.
- Painted in OEM colour EYL (Grey Iceland) for a seamless visual match.
- Keeps tailgate locking and electrical signalling operating reliably.
Function And Common Faults
The tailgate handle is the external control for opening the boot/tailgate and contains a microswitch that reports position to the vehicle’s central locking or body control module. The most common failure modes are mechanical breakage of plastic components (impact or stress), wear of moving parts, corrosion from water ingress, and failure of the microswitch due to age or moisture. When the microswitch fails, symptoms include the tailgate not registering as closed, intermittent opening, or failure to unlock via the central locking system.
Replacement Procedure (Summary)
Suitable for experienced DIY mechanics and professional workshops. Basic steps:
- Remove interior tailgate trim to access the handle mounting points and wiring harness.
- Disconnect the electrical connector for the microswitch.
- Unscrew or unclip the handle fasteners (retain screws/clips for reuse if undamaged).
- Remove the old handle and fit the replacement, ensuring correct orientation and gasket/seal seating to prevent water ingress.
- Reconnect the microswitch connector and test operation of opening, locking/unlocking, and any associated lights or sensors before reassembling trim.
Installation Recommendations
- Always disconnect the vehicle battery before working on electrical components to avoid short circuits and accidental airbag deployment of related systems.
- Handle plastic clips and trim pieces carefully to avoid damage; use appropriate trim tools.
- Ensure sealing surfaces and gaskets are clean and correctly seated to prevent water ingress.
- After installation, check tailgate alignment, lock/unlock functionality, and that the microswitch correctly signals the closed/open status.
- If wiring corrosion is present, clean or replace connectors to ensure reliable electrical contact.
Most Common Reason For Failure
Yearly exposure to weather, mechanical stress from repeated use, and impacts are the primary causes of failure. Plastic fatigue or cracking around the mounting points and water-induced corrosion of the microswitch are typical. Preventive care—keeping seals intact and avoiding excessive force when closing the tailgate—reduces the chance of premature failure.

Notes For Professionals
When fitting this handle in a workshop environment, verify connector pins for corrosion and confirm that the microswitch wiring integrates correctly with the vehicle’s central locking logic. Test the complete cycle (mechanical opening, electrical signalling, and locking) before returning the vehicle to the customer.
