Citroen C3 Grille: Fitment, Sensors & Common Damage

On the C3, the front grille is rarely just a styling panel — on ACC-equipped trims it also houses the radar sensor behind a small panel, worth knowing about if a fault develops.

OEM Part Number: confirm via VIN — radiator grille (aftermarket) Diederichs 4007040 / Prasco CI3312206

Accuracy note: Covers the Citroen C3 (2016-) as listed in the UK aftermarket catalogues. Grilles are sold by trim and facelift, and many generations had different grilles for base, mid and top trims, with or without a radar or camera opening. Where the catalogue splits a grille into left and right or upper and lower sections, buy both halves if both are damaged. 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 match a genuine grille against your VIN if you want a guaranteed fit.

A Genuinely Useful Diagnostic Tip, If Fitted With Adaptive Cruise Control — Citroen C3 Grille

If the radar sensor itself genuinely is at fault, a real, well-corroborated first step before any paid diagnostics: the sensor sits behind a small panel low in the front grille, and simply cleaning this panel thoroughly has resolved the fault entirely in multiple documented cases.

Citroen C3 Grille: Cosmetic on the Surface, Functional Underneath

Treating the Citroen C3's grille as a purely cosmetic part is a common mistake — it also manages radiator airflow, and on many newer models incorporates or surrounds the sensors for adaptive cruise or parking assistance. That functional role is exactly why the correct part number matters more than it might seem.

Before you buy: grille design varies significantly by trim, and higher trims may integrate radar or camera sensors behind or within the grille itself. Always confirm against your VIN before ordering.

Citroen C3 Grille: What It Does

Beyond styling, the grille on the C3 directs airflow to the radiator and, on trims equipped with adaptive cruise control, may house or sit directly in front of the radar sensor used for that system. A grille that looks compatible but lacks the correct sensor cutout can interfere with these systems even if it fits physically.
