Peugeot 108 Grille: Fitment, Sensors & Common Damage

On the 108, if fitted with radar-based cruise, a dealer confirmed a faulty sensor was a known Peugeot issue and replaced it under warranty — a case worth knowing about.

Accuracy note: genuinely worth knowing: grille design on the 108 varies genuinely by trim and radar/camera fitment — cars with adaptive cruise control or lane-keep assist often have a specific grille section with a radar-transparent panel or cutout that standard trims don't need, so a grille that looks identical can be the wrong part if it lacks this feature.

A Genuine, Reassuring Real Case Worth Knowing About

If your adaptive cruise control or collision warning system shows a persistent fault even after cleaning the sensor thoroughly, this is genuinely worth knowing: one documented case saw a dealer investigate a persistent radar fault and confirm it was a genuinely faulty sensor behind the radar grille panel on the front bumper — described directly to the owner as a known issue to Peugeot, and covered under warranty with no charge for the replacement part. If cleaning the sensor and grille area thoroughly hasn't resolved a persistent fault, it's genuinely worth pursuing a proper dealer investigation rather than assuming you'll need to pay, particularly if the car is still within its warranty period.

A genuinely useful, distinct finding worth knowing: if a radar or ACC fault appeared specifically after the battery was disconnected (for any reason — fitting an aftermarket accessory, a jump start, or battery replacement), this can trigger a temporary fault that clears itself once the battery has had a genuine chance to recharge through normal driving — one documented case resolved entirely after roughly 20-30 minutes of driving following a battery disconnect, with no actual sensor fault present at all. If your fault appeared right after any battery work, this is worth trying before assuming a genuine hardware problem.

It's also worth understanding a genuine technical distinction: automatic emergency braking for pedestrians specifically relies on the optical camera near the rear-view mirror rather than the radar behind the grille, since pedestrians don't reflect radar signals as reliably as metal vehicles do. This means a radar fault and a camera-related fault are genuinely different problems affecting different safety functions.

Cosmetic on the Surface, Functional Underneath

The front grille does more than shape a car's face — it manages airflow to the radiator and, on many modern cars, houses or surrounds sensors for adaptive cruise control or parking assistance, meaning the correct part depends on more than just how it looks.

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.

What It Does

Beyond styling, the grille on the 108 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.

Fitment & Compatibility

Grille design differs between trims and across facelifts of the 108, with sportier trims often using a more aggressive mesh design that isn't interchangeable with standard trim grilles. Always confirm the exact part for your specific trim and equipment level before ordering. Whether you're sourcing a replacement grille for your Peugeot 108 from a dealer, specialist, or online marketplace, always check compatibility against your registration or VIN before buying.
