Audi A5 Coupe Grille: Fitment, Sensors & Common Damage

On the A5, an internal heater unit in the radar sensor on related models can genuinely fail separately from the main sensor.

Generation covered: this guide is for the second-generation A5 Coupe (F5 platform, 2016–2024) — the two-door coupe discontinued when Audi renamed the A4 saloon to A5 in 2024. These are entirely different cars despite sharing a name; if your car is a four-door saloon or estate bought new since 2024, this guide does not apply to it. Check your logbook or VIN if you're unsure which car you have.

Cosmetic on the Surface, Functional Underneath

There's more going on behind the Audi A5 Coupe'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.

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.

OEM Part Number: confirm via VIN — radiator grille (aftermarket) Diederichs 1046243

Accuracy note: Covers the Audi A5 Coupe (8T 2007-2016) 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.

Radiator grille (aftermarket)	Diederichs 1046243 (black, glossy); Diederichs 1046940 (chrome/black, glossy); Diederichs 1046242 (chrome/black)
Genuine (OE) numbers quoted	None quoted in the catalogue listings — the genuine grille varies by trim level, facelift and sensor options, so order it against your VIN

S Line and S5/RS5 models use a genuinely different grille design to standard Sport trim, and the 2019 facelift changed the grille shape — pre- and post-facelift grilles aren't interchangeable. Various finish options (chrome, gloss black, dark chrome) also affect which specific part you need.

Audi A5 Coupe Grille: What It Does

Beyond styling, the grille on the A5 Coupe 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.

A Genuinely Useful Piece of Context Worth Knowing About Radar Sensor Faults — Audi A5 Coupe Grille

If the adaptive cruise control has become unavailable, this is genuinely worth knowing before assuming the whole sensor needs replacing: the radar sensor contains an internal heater unit on related Audi models, and this specific heater has been documented failing on its own, with the main sensor remaining fine.

A genuinely important clarification worth knowing about fault codes: a specific diagnostic code referring to the sensor being misadjusted or incorrectly positioned does not automatically mean a new sensor is required — it may simply need proper recalibration by a dealer.

It's also genuinely worth knowing that removing the front bumper for entirely unrelated work has been documented damaging the radar units or their wiring in the process on related models.
