Technical Information

• Manufacturer: Stellantis (Citroén/Peugeot)
• Model: Peugeot 407 (incl. Sedan / SW / Coupé range)
• Product Codes: 1517A7, 151877
• Other Numbers: EXL (Paint Code – Obsidian Black)

How To Replace

Replacement is straightforward for experienced technicians and skilled DIYers. Typical steps:

• Open the fuel flap and remove the inner trim or access panel to reach fasteners.
• Remove screws or clips holding the housing and hinge in place (keep track of fasteners and plastic clips).
• If present, unplug the locking actuator connector before removing the assembly.
• Carefully detach the flap and housing from the body, avoiding damage to surrounding paint.
• Install the new unit, align the hinge and latch, reconnect the actuator, and secure all fasteners.
• Check operation of the flap, latch engagement and (if applicable) central locking function.

Estimated labor time: approximately 0.5–1 hour depending on access and whether the locking actuator or trim must be removed.

Installation Recommendations

• Use plastic trim tools to avoid scratching surrounding paint and panels.
• Replace any damaged clips or corroded screws with new fasteners for a secure fit.
• Lubricate hinge points lightly and check the rubber seal for signs of wear; replace seal if degraded.
• When working near the painted area, protect surfaces with tape or soft cloth; touch up exposed paint to prevent corrosion.
• After installation, verify flap alignment and smooth opening/closing; adjust hinge or striker if necessary.

Common Failure Reasons

• Impact Damage: Minor collisions or knocks at the filler area commonly crack or deform the flap.
• Hinge Or Latch Wear: Plastic hinges and clips fatigue over time and can break, preventing proper closure.
• Corrosion: Rusted fasteners or body corrosion around the filler housing can seize components or cause deformation.
• Locking Actuator Faults: On models with a locking mechanism, the actuator can fail electrically or mechanically.
• Paint Damage And Chipping: Exposed metal from chips accelerates corrosion and further weakens the assembly.
