About part number 51128070949

A rear bumper cover forms the outer body panel at the back of the vehicle. It belongs to the exterior bodywork system and mounts directly to the rear structure and inner bumper reinforcement. It protects internal components from minor impacts, helps manage airflow around the back of the car, and provides a neat finish to the vehicle body that the driver sees every time they walk up to the rear.

To confirm that this part is correct for your vehicle, check the manufacturer part number stamped directly onto the plastic moulding. On a rear bumper cover, this number is usually moulded into the inside surface or near the lower mounting tabs. You must match the part number 51128070949 exactly to guarantee correct fitment, as the part number is what determines compatibility.

Rear bumpers are most often replaced due to cosmetic damage, cracks, or scuffs caused by low-speed impacts and parking incidents. Because this item requires a respray to match your paintwork, anyone fitting it will usually need appropriate paint materials, replacement plastic mounting clips, and any trim inserts or parking sensors transferred over from the original panel during installation.

  • Part type: Bumpers & Reinforcements.
  • Specification: colour RESPRAY REQUIRED.
  • Position on the vehicle: Rear.

About this kind of part: bumper covers

A bumper cover is the painted plastic skin across the front or the rear of a car. It is not a structural part. Behind it sit a foam or honeycomb absorber and a steel or aluminium reinforcement bar, and those are what take an impact. The cover carries the grille apertures, the number plate plinth and the openings for parking sensors, washer jets and tow eyes, so one model can take several different covers depending on how it was specified when new.

Why people replace one

  • A knock in a car park or a light collision has cracked or torn the plastic. A tear can be plastic-welded, but it rarely returns to a finish that will take paint without showing.
  • The paint has faded or crazed differently from the panels around it. A bumper flexes and sits low in the spray from the road, so it ages faster than a wing.
  • The mounting tabs along the top edge or inside the wheel arches have snapped, so the cover stands proud of the panel next to it.
  • An earlier repair has been filled and has begun to lift.

Fitting it

  • It is held by screws along the top edge, screws or clips inside each wheel arch, and plastic nuts underneath the car.
  • Lamps, grilles, sensors, washer jets and the number plate plinth usually move across from the old cover.
  • A cover is supplied either in primer or in the colour it was sprayed when new. A matching finish needs the paint code from the car's own identification plate.
  • Parking sensors go back into their own openings, and the trim rings around them are often specific to the colour.

Making sure it is the right one

  • Match the part number moulded into the old cover rather than matching the shape. A facelift changes the number while the outline can look almost the same.
  • Check whether the car has parking sensors. A cover with no sensor openings cannot be used on a car that has them, and drilling one is not a repair.
  • Count the openings and compare them: fog lamp apertures, the tow eye cover and any camera or washer cut-out differ between trim levels on the same model.

What to look for in the photographs

A Part number — Moulded into the inside face, usually towards one end. This is the number to match against your own cover.
B Parking sensor openings — Either a row of openings across the face or none at all. This is what decides whether the cover will fit your car.
C Upper mounting tabs — The row of tabs along the top edge that screw to the slam panel. Look for any that are cracked or missing.
D Wheel arch returns — The ends that wrap around into the wheel arches. These are the first part to crack in a knock, and the easiest to overlook.
E Lamp and grille apertures — The openings for fog lamps, the grille and any camera or sensor. Hold them against your own cover before buying.
