OEM Part Number: confirm via VIN — front bumper (aftermarket) Diederichs 4073451 / Klokkerholm 0548901A1

Accuracy note: Covers the Citroen C4 Cactus (2014-2020) 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.

A Genuine Cost Figure Worth Knowing Before Ordering Sensors — Citroen C4 Cactus Front Bumper

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, since not every "compatible" listing is equally reliable.

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, unusual pattern distinct from a simple sensor or wiring failure, pointing toward a module logic issue tied specifically to ignition state rather than the sensors themselves. If you're experiencing this exact pattern, it's worth describing it precisely this way to a technician, since it narrows down the likely cause considerably compared with a generic "sensors don't work" description.

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 before paying for diagnostics: 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 normally has likely failed, letting you narrow down the problem yourself.

Citroen C4 Cactus Front Bumper: More Than Just a Plastic Panel

The Citroen C4 Cactus's front bumper routinely integrates parking sensors, adaptive cruise control radar, and fog light housings, which means replacing it after even minor impact damage often involves more than a straightforward swap.

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.

Citroen C4 Cactus Front Bumper: What It Does

Beyond absorbing minor impacts, the front bumper on higher trims of the C4 Cactus 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.
