Mercedes-Benz A-Class Grille: Fitment, Sensors & Common Damage

Confirmed: on this platform, the adaptive cruise control radar sensor is positioned in the lower front bumper behind the grille mesh, not behind the central star emblem — plus an honest account of a "Distronic-compatible" aftermarket grille still breaking the system.

OEM Part Number: confirm via VIN — radiator grille (aftermarket) Van Wezel 2929510 / Diederichs 1682541

Accuracy note: Covers the Mercedes-Benz A-Class (W176 2012-2018) 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)	Van Wezel 2929510; Diederichs 1682541 (chrome/black); Diederichs 1682443 (black, glossy); Prasco ME3302001 (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

Mercedes-Benz A-Class Grille: Cosmetic on the Surface, Functional Underneath

The Mercedes-Benz A-Class's front grille isn't purely cosmetic, even though styling is what most buyers notice first — it directs airflow to the radiator, and on many current cars, doubles as a mounting point for adaptive cruise radar or parking sensors. That means picking the right part is about more than matching the look.

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.

Mercedes-Benz A-Class Grille: What It Does

Beyond styling, the grille on the A-Class 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.

Confirmed: A Genuinely Specific Finding Worth Knowing — Mercedes-Benz A-Class Grille

If you're trying to locate the adaptive cruise control radar sensor, this is genuinely worth knowing specifically for this model: on this platform, the sensor is positioned in the lower front bumper behind the grille mesh, rather than behind the central Mercedes star emblem as it is on some other models — worth knowing this specific location before assuming you're looking in the wrong place.

A genuinely honest, real account worth knowing before fitting an aftermarket grille: one documented case saw an aftermarket grille, specifically marketed as being compatible with this system and using the same badge and camera-look housing, still trigger a constant "radar sensor dirty" message once fitted, disabling cruise control, lane assist, collision assist, and active park assist simultaneously all at once. Putting the original grille back on resolved the issue entirely for that owner, worth knowing marketing claims of compatibility aren't always reliable, and worth being prepared to revert to the original grille as a troubleshooting step if a similar fault appears after fitting a replacement.

It's also genuinely worth knowing that a persistent radar fault can sometimes simply be a cable that wasn't fully reconnected after other front-end work, such as headlight-related recall work, worth checking this specific connection before assuming a genuine sensor fault, particularly if the fault appeared shortly after other work was carried out on the front of the car.
