About part number L1BJ-17096-A

A rear bumper cover and diffuser assembly forms part of the exterior bodywork at the back of the vehicle. It mounts to the rear body structure and chassis brackets, shielding internal components from road spray and light impacts. The diffuser section helps to manage airflow beneath the vehicle. When fitted correctly, it aligns with the surrounding body panels to give a clean finish and a secure housing for rear parking sensors, reflectors, or lights.

To confirm this part matches your vehicle, check the engineering part number stamped into the plastic on the reverse side of your original casing. The part number for this item is L1BJ-17096-A. Matching this exact number against the old part is the only way to guarantee correct fitment, as physical shape and mounting points vary across different specifications.

Rear bumper assemblies are commonly replaced after low-speed impacts, parking incidents, or when the mounting tabs break. When replacing this unit, you usually need replacement plastic retaining clips, fixing bolts, and any trim clips that hold the wiring loom for parking sensors or number plate lights in place.

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.
