Intended Applications

Designed for use on Peugeot 407 Sedan models that require a replacement fuel filler cap/cover in KKQ Red Profond. Suitable for body repair shops, service garages and experienced DIY mechanics replacing a damaged fuel flap assembly.

Installation Recommendations

Recommended Steps: Remove the old fuel flap assembly by opening the filler door, removing the visible screws or plastic retainers, and releasing the hinge clips. Disconnect any retaining springs or the filler cap lock mechanism if present. Install the new assembly by aligning mounting points, snapping hinge clips into place and securing with the original or OEM-equivalent fasteners. Check the filler cap seal for proper compression and ensure the door closes flush with the surrounding body panel. Avoid overtightening fasteners to prevent cracking the plastic. If paint touch-up is required, mask surrounding panels to protect finish.

Common Failure Causes

Fuel filler covers typically fail due to external impact (minor collisions or parking scrapes), broken hinge pins or plastic clips, corrosion where metal components contact road salt, and wear of seals or latches from repeated use. Paint damage and fading are common on exposed flaps, especially on older vehicles. Replacement is usually required after physical damage or when the door no longer closes or seals correctly.

Practical Tips For Fitment

• Verify color code KKQ against the vehicle’s paint code to ensure a close match.
• Retain original fasteners where possible; replace damaged clips to ensure secure mounting.
• Inspect the filler neck seal and locking mechanism during replacement and renew if hardened or torn.
• Perform a final check with the fuel cap installed to ensure no rubbing or misalignment that could damage the paint.

Additional Notes

This assembly includes the filler neck housing and is intended as a bodywork replacement part. Suitable for professional installation but can be fitted by experienced DIY mechanics familiar with exterior panel fastenings and trim clips.

This fuel filler cap cover is designed for the Peugeot 407 Sedan and is commonly searched under the code 1517A6. Built as an exterior body part, it restores the original look of the vehicle, protects the fuel filler neck from dirt and moisture, and ensures proper closure of the filler opening. Ideal for professional workshops and DIY enthusiasts who prefer to order parts by product code, the panel comes painted in Manitoba Gray (Color Code EZQ/EZQC) for a direct visual match on vehicles with the same paint option.

Function And Fit

The filler cap cover protects the fuel filler neck from water, dust and road debris while contributing to the vehicle’s exterior aesthetics. It must align precisely with the surrounding bodywork and latch securely to prevent rattles and ingress. Correct paint code matching ensures minimal visual difference when fitted.

Replacement / Installation

• Open the fuel filler flap and inspect retaining screws or hinge fasteners.
• Remove fasteners (typically screws or bolts) securing the hinge and release the flap assembly; keep original screws if reusing.
• Transfer any latch components, gasketing or paint-protected clips from the old cover to the replacement if required.
• Fit the new cover, align to body panel gaps and torque the fasteners to manufacturer recommendations.
• Check operation of the flap and latch; correct alignment if rubbing or misclosure is observed.

Installation Recommendations

• Perform replacement on a level surface and avoid forcing the flap to prevent damage to hinge pins or latch components.
• If painting is required, use the exact paint code (EZQ/EZQC) and allow proper curing before installation to avoid scuffs.
• Inspect surrounding sealing and hinge brackets for corrosion or damage and replace as needed for a long-term repair.

Why This Part Fails

Fuel filler covers most commonly fail or require replacement due to minor collisions (side or rear impacts), corrosion of hinge or fasteners, latch wear, vandalism or paint damage from road debris and environmental exposure. In many cases the structural panel remains intact but the hinge or latch becomes worn, causing misalignment or an inability to close securely.

This replacement fuel filler cover is designed for Peugeot 407 sedan models and is often searched by part numbers 1517A6 and 151877 (EYLC). The unit includes the complete fuel filler neck housing, ensuring correct fitment and an OEM-style finish in Grey Iceland. Robust construction and original mounting points make it a direct-fit exterior body part that restores appearance and protects the fuel inlet from dirt, moisture and minor impacts.

Technical Information

• Model: Peugeot 407 Sedan
• Product Codes: 1517A6, 151877
• Other Numbers: EYLC (Color Code EYL – Paint Grey Iceland)

Part Function

The fuel filler cover conceals and protects the fuel filler neck and cap. It prevents contamination from dirt and water, preserves the vehicle’s exterior appearance, and maintains the correct interface for a sealing fuel cap. The attached filler neck housing secures the fuel inlet components and ensures proper alignment with the fuel cap.

Compatibility and Fitment

Fits Peugeot 407 Sedan models that use part numbers 1517A6 or 151877 (check the code on the original part). The unit is supplied in the factory color EYL (Grey Iceland) for a seamless exterior match. Common searches reference the codes 1517A6 and 151877 — include these when verifying fitment for faster results.

Replacement Procedure

Basic removal and installation steps (overview for experienced mechanics and DIY enthusiasts):

• Open the fuel filler door and remove any visible fasteners securing the filler flap assembly.
• Access the rear of the filler housing from inside the luggage compartment or wheel-arch liner; remove trim or liner panels as required.
• Disconnect any release cable or actuator and unclip the mounting tabs holding the filler housing.
• Remove the complete old assembly and transfer any required clips, gaskets or actuator components to the new unit if not supplied.
• Fit the new filler cover and housing, secure all fasteners, reconnect the release mechanism and test operation for smooth opening/closing and correct alignment.
• Reinstall trim panels and verify paint finish and gap alignment.

Installation Recommendations

• Use Correct Tools: Use plastic trim tools to avoid scratching inner panels and a torque screwdriver where specified.
• Check Seal Condition: Replace any worn gaskets or clips during installation to ensure weather-tight fitment.
• Paint Protection: If performing bodywork or paint touch-up, mask surrounding panels to maintain the factory finish.
• Test Operation: Verify release actuator and latch function after installation, and confirm the filler cap seals correctly.
• Professional Help: If the assembly includes an integrated actuator or if access requires major disassembly, consider professional installation.

Why This Part Fails Most Often

• Impact Damage: Collisions with fuel nozzles, minor parking impacts or vandalism can crack the flap or break hinge mounts.
• Broken Hinges or Clips: Plastic hinge pins and mounting clips deteriorate over time and can shear off.
• Corrosion and Wear: Long-term exposure to moisture and road salt leads to corrosion of metal components and poor fitment.
• Latch/Actuator Failure: Mechanical latches or central-release actuators can seize or fail, preventing proper closure.
• Paint Damage: Chipped or damaged paint around the filler increases corrosion risk and reduces visual match.

Choose the correct part number (1517A6 or 151877) and color code (EYLC) to ensure a perfect fit and finish. Replace worn seals and damaged clips at the same time to restore reliable operation and preserve the vehicle appearance.
