Fitment And Compatibility
Intended for Citroën C4 Grand Picasso models that require the above part numbers and painted in KGQ (Kyanos Blue). Always verify the part number stamped on the original filler cover before installation.

Function
The fuel filler cap cover protects the filler neck and cap from environmental contamination and mechanical damage while maintaining the vehicle’s exterior appearance. It forms the visible outer part of the fuel filler assembly and ensures proper sealing and alignment with the surrounding bodywork. On some trim levels the fuel flap operation is integrated with the vehicle’s central locking system; this listing refers to the external cover/panel itself.
Installation Recommendations
- Prepare Tools: small ratchet, Torx/Phillips bits or screws as used on the vehicle, trim clip tools, and a torque driver if specified by the repair manual.
- Removal: Open the filler flap and remove hinge fasteners or clips. On some model years access to the hinge fasteners may be easier from the inner wheel arch or trunk side by removing the liner.
- Fitment: Align the new cover with the hinge and latch points, tighten fasteners evenly and check for correct gap and flush fit with surrounding body panels.
- Adjustment: If alignment is off, loosen hinge fasteners slightly, adjust position and retighten to the correct torque. Ensure the latch releases and closes smoothly without binding.
- Finish: Inspect paint finish for any transport scuffs before installation. If repainting or touch-up is required, follow manufacturer paint-preparation procedures to avoid mismatch.
Replacement Frequency & Maintenance
Fuel filler flaps do not have a fixed service interval. Replacement is normally required after impact damage, corrosion of hinge/latch components, or progressive paint deterioration. Regular cleaning of the hinge and latch area and occasional lubrication of moving points will extend service life.
Why The Part Most Often Fails
Common causes of failure include stone chips or minor collisions that break the hinge or deform the flap, corrosion of hinge pins and fasteners from road salt and moisture, loss of paint adhesion from UV exposure, or vandalism. Latch failure can result from debris ingress or corrosion preventing proper engagement.
Notes For Professionals And DIYers
This part is suitable for bodyshops and independent mechanics needing a direct-fit, color-matched replacement. Because many customers search by OE number, listing the correct codes (9654052080, 1517E4, 1517E3) speeds up finding the right item. When replacing the flap, check hinge hardware and latch condition and replace corroded fasteners to ensure a durable repair.
