Cheap Mercedes-Benz GLS Engine Mount

The GLS spans two distinct generations here: the X166 (2016–2019) and the X167 (2019 onwards), so a 2017 mount comes from a different generation than a 2020 car. Mounts are engine-code specific, and even where the same engine family carried across generations, the mounting geometry and subframe design changed between X166 and X167. You should confirm with the breaker against your exact registration and engine code before purchasing.

Yes, the engine code is the single most important detail for this purchase — the GLS was offered with multiple petrols and diesels across both the X166 and X167 generations, and each engine has its own mount configuration. Your engine code is on your V5C or can be retrieved via a VIN check, and it is the first thing any breaker will need from you. Quoting your engine code upfront will save time and reduce the risk of ordering the wrong mount.

Trim names on the GLS reflect the engine fitted, so a GLS 350d and a GLS 400d run different engines with different engine codes, and the mounts are not necessarily interchangeable. The good news is that trim-level cosmetic differences — interior spec, colour, optional equipment — have no bearing on engine mount fitment whatsoever. Always match by engine code rather than badge, and confirm with the breaker that the donor vehicle's engine code matches yours.

The X166 GLS received a facelift in 2019 before the generation ended, but whether ancillary mounting components changed during that mid-production update is something you should confirm with the breaker against your registration rather than assume. Engine mounts primarily follow the engine code, so if the donor car shares your exact engine code, fitment is more likely — but mid-production mounting changes can occur. Give the breaker both your registration and engine code so they can cross-reference against the donor vehicle.

Yes, petrol and diesel variants of the GLS use different engines with different engine codes, and the mounts are specific to each engine rather than shared across fuel types. A mount from a GLS 350d diesel will not suit a GLS 400 petrol even if both cars are from the same year. Always confirm your fuel type and engine code with the breaker before they pull the part.

Yes, engine mounts are fitted to every variant of the GLS regardless of engine or drivetrain — they are a fundamental component that secures the engine to the subframe on all petrol and diesel models across both the X166 and X167 generations. There are no GLS variants where engine mounts are absent, unlike parts such as intercoolers which only appear on certain engine types. The key variables are engine code and generation, both of which you should supply to your breaker when requesting a quote.
