About part number 8Y4809906

A fuel tank filler flap cover protects the fuel cap and filler neck from dirt, water and road debris while maintaining the smooth bodyline of the vehicle. Situated on the outer wing, it forms part of the exterior bodywork and latches securely into the body structure when closed. When functioning correctly, the flap sits flush with the surrounding bodywork, opens smoothly when released, and latches firmly to keep weather and grime away from the fuel area.

To confirm this part is correct for your vehicle, you must match the part number 8Y4809906 directly with the number stamped or printed on your original flap. On a part like this, the manufacturer reference is usually stamped into the plastic housing on the inner face or near the hinge mechanism. Matching this exact part number is the only way to ensure the hinge mounts, latch mechanism and outer profile fit correctly.

When replacing a filler flap cover, you may also need replacement mounting clips, a latch spring, or the rubber seal that sits around the housing. Drivers usually replace this part because the outer panel has suffered bodywork damage, or because the plastic hinge mechanism has snapped and no longer holds the door closed against the body.

  • Part type: Oil Drain Plugs, Filler Caps & Dipsticks.
  • Specification: country of origin Germany; colour Black.

About this kind of part: fuel filler flaps

A fuel filler flap is the small painted door over the filler neck, with its hinge and usually a spring or a damper behind it. On an electric or a hybrid car the same part covers the charging socket and is often larger and electrically released. It is painted to match the body, which is why it is replaced far more often than it fails: the flap sits where people lean, and it is one of the few painted parts a careless hand touches every week.

Why people replace one

  • The flap has been creased or dented, usually by being pushed shut against the filler cap or by a knock at a pump.
  • The hinge has broken or the spring has failed, so the flap no longer stays shut or no longer stays open.
  • The paint has faded or the lacquer has lifted, which shows badly because the flap sits in the middle of a large flat panel.
  • The release mechanism or the electric actuator has failed and the flap no longer opens from inside the car.
  • A rear quarter panel has been repaired and the original flap was damaged in the process.

Fitting it

  • Most flaps unbolt from the hinge inside the filler recess, sometimes with the hinge as one assembly and sometimes as a separate part.
  • On a car with an electric release, the actuator and its loom stay with the car and the flap comes off on its own.
  • The seal or the foam around the recess is worth checking at the same time, because it is what stops water collecting in the bottom of it.
  • A flap is supplied in primer or in the colour it was sprayed when new, and a matching finish needs the paint code from the car's own identification plate.

Making sure it is the right one

  • Match the part number. A petrol or diesel flap and a charging flap for the same model are different parts, and so are the versions before and after a facelift.
  • Check whether yours comes with the hinge. Some models sell the flap alone and some sell it as an assembly, and the hinge is often the part that broke.
  • Compare the curvature against your own panel. A flap is pressed to the shape of one body line and will not sit flush in another.
  • Treat a painted used flap as a starting point for colour rather than a match, because it has aged with the car it came off.

What to look for in the photographs

A Part number — Stamped or on a label on the inner face, often under the hinge.
B Hinge — Whether the hinge is included and whether it is straight. A bent hinge is why most flaps no longer sit flush.
C Spring or damper — The mechanism that holds the flap open or shut. It is often what has failed, and it is sometimes a separate part.
D Inner face — The back of the flap, where water sits and where corrosion starts on a steel one.
E Outer surface — Look across the face at a shallow angle. A crease or a dent in a flat panel this small is invisible in a straight-on photograph.
