On the C4, 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.

A Genuinely Useful Diagnostic Tip, If Fitted With Adaptive Cruise Control
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 C4 Grille: Cosmetic on the Surface, Functional Underneath
There's more going on behind the Citroen C4's front grille than its styling suggests: it channels air to the radiator, and on plenty of modern cars it also houses or surrounds sensors for adaptive cruise control and parking assistance. Getting the correct part means accounting for all of that, not just appearance.

Grille design varies by trim and whether the bumper has fog lights fitted (some grille sections incorporate fog light openings, others don't), and the 2024 facelift revised the front-end styling. Confirm your exact trim and build date before ordering.
Citroen C4 Grille: What It Does
Beyond styling, the grille on the C4 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.
