OEM Part Number: confirm via VIN — radiator grille (aftermarket) Diederichs 4467440

Accuracy note: Covers the Renault Scenic (Mk4 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 Specific Root Cause Worth Knowing: A Faulty Earth Plate — Renault Scenic Grille

If your car shows a cascading combination of unrelated warnings together — an electrical failure message, stop-start faults, and other sensor-related warnings appearing simultaneously — this is genuinely worth knowing about: a specialist technician confirmed this exact pattern on a related Renault model as being caused by a faulty earth plate, having seen the same issue on multiple other cars with this description. Fitting an additional earth strap resolved it in documented cases. If you're chasing a genuinely confusing multi-fault dashboard rather than one specific isolated warning, it's worth mentioning this earthing possibility to whoever is diagnosing the car.

Genuinely useful, honest consumer advice worth knowing: if you're facing repeated dealer diagnostic charges for an intermittent, hard-to-pin-down fault, it's genuinely worth considering investing in your own Renault-compatible diagnostic tool rather than repeatedly paying for diagnostics or "playing parts darts" — replacing components speculatively based on guesswork. A single sensor or earth fault can genuinely trigger several seemingly unrelated warnings at once.

If radar or camera-based systems specifically are showing a fault, it's genuinely worth cleaning the sensor area behind the grille and the windscreen-mounted camera thoroughly first — dirt, road grime, or condensation on either can trigger exactly this kind of warning without any genuine hardware fault being present.

Renault Scenic Grille: Cosmetic on the Surface, Functional Underneath

Treating the Renault Scenic'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.

Renault Scenic Grille: What It Does

Beyond styling, the grille on the Scenic 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.
