Citroen C4 Front Bumper: Fitment, Sensors & Common Damage

On the C4, a real cost figure worth knowing: genuine parking sensors run around £117 each — plus a distinct fault where sensors disable themselves when the ignition turns on.

Generation covered: this guide is for the current C4 (launched 2021, facelifted 2024), with particular focus on 2021–2023 registered examples now old enough for parts to be a common search. Check your logbook or VIN if you're unsure which generation you have.

A Genuine Cost Figure Worth Knowing Before Ordering Sensors

Worth knowing before pricing up a repair: genuine Citroën/Peugeot parking sensors have been quoted at around £117 each from the dealer — a significant cost if more than one has failed. Quality aftermarket alternatives claiming compatibility with the genuine OEM part number are available considerably cheaper, though it's worth confirming with the seller that colour-coding and genuine fitment compatibility are accurate before ordering.

A genuine, distinct fault pattern worth knowing about: one documented case saw parking sensors that could be manually enabled with the engine off, but automatically reverted to disabled the moment the ignition was turned on — a specific pattern pointing toward a module logic issue tied to ignition state rather than the sensors themselves. If you're experiencing this exact pattern, describing it precisely this way to a technician narrows down the likely cause considerably.

It's also worth knowing that a single faulty sensor can sometimes cause the entire system to log a fault without pinpointing which one — a genuinely useful, free test worth trying: with the sensors switched on, listen closely to each one for an audible buzz or click as it pulses; a sensor that stays silent while others respond has likely failed.

Citroen C4 Front Bumper: More Than Just a Plastic Panel

Even a low-speed knock to the Citroen C4's front bumper can be more involved to fix than it looks, since it usually integrates parking sensors, adaptive cruise radar, and fog light housings — all needing attention beyond a plain panel replacement.

Before you buy: bumper specification varies significantly by trim, particularly around parking sensor cutouts, radar mounting points and fog light provisions. Always confirm against your VIN before ordering.

Accuracy note: Covers the Citroen C4 (2010-2018) as listed in the UK aftermarket catalogues. A front bumper is a body-coloured plastic skin, so what you buy is a primed cover that still needs painting to your paint code, and the right one depends on body style, trim, facelift date and the holes moulded into it for parking sensors, fog lights, headlamp washers or a tow eye cover. A cover without the right holes cannot be drilled accurately at home. The references below are UK aftermarket catalogue listings for this generation, labelled by brand with the fitment details the catalogue gives; carmakers rarely publish the genuine number against these, so order a genuine cover against your VIN if you want a guaranteed match. The splitters, outer sections and trims listed separately are the parts most often sold on their own after a car-park knock.

Front bumper covers (aftermarket)	Prasco CI5101011 (primed, with parking sensor holes); Prasco CI5101001 (primed); Van Wezel 0989575 (primed); Van Wezel 0989574 (primed); Diederichs 4074050 (primed)
Splitters, outer sections & trims	None listed separately
Genuine (OE) numbers quoted	None quoted in the catalogue listings — the genuine cover varies by body style, trim, parking sensors and fog lights, so order it against your VIN
Fitment notes	Match body style, trim, facelift date and the holes for parking sensors, fog lights and washer jets; covers come primed and need painting to your paint code before fitting.

Bumper covers also vary by whether the car has front parking sensors or a front camera pre-fitted, and by fog light equipment — confirm your exact specification matches before ordering, since a bumper with the wrong cutouts (or none at all) isn't a straightforward swap even if it fits physically.

Citroen C4 Front Bumper: What It Does

Beyond absorbing minor impacts, the front bumper on higher trims of the C4 often houses parking sensors, the radar sensor used for adaptive cruise control, and fog lights. A bumper that looks compatible can still be missing the correct cutouts or mounting provisions for your specific trim's equipment.
