Second Hand Mercedes-Benz GLS Bonnet Latch

The GLS (X166) ran from 2016 to 2019, and the second-generation GLS (X167) arrived in 2019 with a significant redesign, so these two generations do not share a bonnet latch. Within the X167 generation, a facelift arrived in 2023 updating the front end, and whether the bonnet latch itself interchanges across that 2023 boundary is something you should confirm with the breaker against your registration. Always quote your reg when requesting a quote so the breaker can cross-reference the exact part.

Engine choice makes no difference to bonnet latch fitment on the GLS — the latch is part of the front bodywork structure and is shared across diesel, petrol, and hybrid variants within the same generation. So a latch from a 350d and one from a 400d of the same generation are the same part. Just make sure you and the breaker are comparing the same generation (X166 or X167) rather than mixing years across the 2019 redesign.

Trim level does not affect bonnet latch fitment on the GLS — whether the car is a standard GLS, AMG Line, or AMG 63, the latch mechanism itself is the same within a generation. There may be cosmetic differences to the surrounding front-end panels between trims, but the latch is a functional component that does not change. Confirm the generation year with your breaker and you should be fine.

A 2018 GLS is the first-generation GLS, built on the X166 platform, which covers the 2016 to 2019 model years in the UK. Tell the breaker it is an X166 GLS and give them your registration, as this is the most reliable way for them to pull the correct part number. The X167 second generation that replaced it from 2019 uses a different bonnet latch design and the two will not interchange.

Yes — the GLS is a conventional front-engined SUV with a forward-opening bonnet, so it has a standard bonnet latch and release mechanism. This applies to every variant across both the X166 (2016–2019) and X167 (2019–present) generations regardless of engine, drivetrain, or trim. You are looking for the right part on the right model, so proceed with your enquiry quoting your registration for the most accurate match.

The GLS moved from the X166 to the all-new X167 platform in 2019, and a 2021 car is firmly within the X167 generation, so both a 2019 X167 and a 2021 X167 should be the same generation for latch purposes. However, the 2019 changeover year can sometimes mean early and late production cars differ in detail, so it is worth asking the breaker to verify the part number against both registrations before you commit. This is a straightforward check any experienced Mercedes breaker should be able to do quickly.
