Second Hand Mercedes-Benz GLS Bonnet

The GLS has two main generations: the first-generation X166, produced from 2016 to 2019, and the second-generation X167, which launched in 2020 and received a facelift in 2023. Bonnets are not interchangeable between the X166 and X167 as they are entirely different platforms with different front-end designs. Within each generation, the bonnet is shared across the range regardless of engine or specification, so focus your search on matching the correct generation to your registration.

Yes, both a 2017 and a 2019 GLS are X166-generation models, so the bonnet panels come from the same platform and should be compatible. The X166 ran from 2016 to 2019 without a significant facelift that affected the bonnet itself, so year differences within that range are not a concern for fitment. Always confirm the exact part with the breaker against your registration to be certain.

The X167 GLS received a facelift in 2023, and while the facelift primarily affected the front grille, lights and bumper, whether the bonnet itself interchanges across that 2023 boundary is something you should confirm with the breaker against your specific registration. Name the facelift year clearly when contacting breakers so they can check whether the panel is the same pressing or a revised one. Do not assume compatibility across that boundary without verification.

Trim level does not affect bonnet fitment on the GLS — the same bonnet panel is used across standard, AMG Line and any other specification within a given generation. You may find that bonnets sourced from different trim levels look identical, though you should be aware that cosmetic differences in badges or any trim-mounted features are separate items. Confirm the generation matches your registration and the trim level can be disregarded for the bonnet itself.

No — a 2018 GLS is an X166-generation car while a 2020 GLS is an X167, and these are completely different platforms with different front-end structures and styling. These bonnets are not interchangeable, so you must source a bonnet from an X167 (2020 onwards) to match your car. Make sure the breaker you contact knows you need an X167 part and confirm against your registration.

No — engine choice and wheelbase make no difference to bonnet fitment on the GLS, as the front-end panel is shared across all drivetrain and body configurations within a generation. The key detail to get right is the generation: X166 (2016–2019) or X167 (2020 onwards), and whether your car falls either side of the 2023 X167 facelift. Confirm the correct generation with your breaker and the other variables can be set aside.
