Used Mercedes-Benz GLS Front Grille

The GLS nameplate covers two main generations: the first-generation X166, sold from 2016 to 2019, and the second-generation X167, which launched in 2020 and is still current. Grilles are specific to their generation, so an X166 grille will not fit an X167 and vice versa. Always quote your registration to the breaker so they can confirm the exact generation before ordering.

Both the 2017 and 2019 GLS belong to the same first-generation X166 platform, so the front end architecture is shared across those years. That said, confirm with the breaker against your registration, as minor running changes to trim attachments or sensor cutouts can affect fitment even within a generation. A good breaker will cross-reference your VIN to be sure.

The X166 GLS received a facelift in 2019, so a 2016 car and a 2018 car are both pre-facelift models and should share the same front-end design. However, if you are looking at a 2019 part for an earlier car or the other way around, that crosses the facelift boundary and you must confirm directly with the breaker against your registration, as grilles and surrounding panels commonly change at facelifts. Never assume interchange across that boundary without checking.

Engine choice and trim level do not affect which front grille shell fits your GLS, as front-end panels are shared across the range within a generation. That said, AMG Line and AMG-badged variants often carry a different grille design with a distinctive mesh or chrome surround compared with the standard trim, so a direct swap from a different trim may look visually different on your car. Confirm the grille style with the breaker so you get one that matches your existing front end.

Engine specification has no bearing on front grille fitment for the GLS — the panels are shared across petrol, diesel, and AMG variants within the same generation and facelift period. The key things to match are generation (X166 or X167) and whether the car is pre- or post-facelift. Quote your registration to the breaker and they will identify the right part without needing to know your engine code.

Give the breaker your full registration number, as this allows them to confirm the exact generation, facelift status, and any trim-specific grille design. It is also worth checking whether your car has any parking sensors or cameras mounted in the grille, as these require matching cutouts on the replacement part. A reputable breaker will cross-reference all of this before sale, but fitment is never guaranteed, so confirm everything before parting with money.
