About part number 8054021

A rear bumper cover forms the outer bodywork at the back of the vehicle. It protects the structural crash impact bar, covers the internal mountings, and gives the vehicle its finished visual appearance. It is secured to the main body shell and wheel arch liners, and it often houses parts such as parking sensors, reflectors, and number plate lights. When it is correctly fitted, the bodywork lines sit flush and the rear components remain securely protected from road dirt and moisture.

To confirm that this rear bumper is correct for your vehicle, you must match the part number directly. The manufacturer part number for this item is 8054021. On plastic bumper covers, this number is usually stamped or printed onto the inner surface, so you may need to inspect the back of your original cover to read it. Matching this exact number is the only way to guarantee a correct fit, as shape and mounting points vary between different trim options.

A rear bumper cover is usually replaced after low-speed impacts, scuffs, or when the mounting tabs crack and prevent it from sitting correctly. When changing this part, you often need replacement plastic rivet clips, trim fixings, and fresh double-sided tape for any badges or reflectors that must be transferred from the old panel.

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.
