Cheap Mercedes-Benz GLS Turbo

The Mercedes-Benz GLS exists in two main generations: the X166 (2016–2019) and the X167 (2020 onwards), and turbos are not straightforwardly interchangeable across that boundary due to engine and ancillary differences. Within the same generation, fitment is driven primarily by engine code — for example, a 3.0-litre diesel OM656 unit in the X167 will need a turbo matched to that specific code, regardless of the year on the V5. Always confirm with the breaker using your registration or engine code before purchasing.

The 400d and 350d use different engines — the 400d uses the six-cylinder OM656 and the 350d uses the OM642 — so their turbos are not the same part and will not interchange. Engine code is the deciding factor here, not the badge or displacement name on the tailgate. Supply your engine code to the breaker so they can match from the correct donor vehicle.

AMG Line is a cosmetic and equipment trim level, not a separate mechanical specification, so it does not affect which turbo your GLS requires. What matters is the engine code, fuel type, and which generation (X166 or X167) the car belongs to — the AMG Line badges, bodykit, and interior upgrades make no difference to turbo fitment. Confirm your engine code with the breaker and ignore the trim name when sourcing the part.

A 2019 GLS sits in the first generation, the X166 (2016–2019), just before the X167 launched for 2020. This matters significantly for turbo sourcing because the two generations use different engine families, so a turbo from an X167 donor will not be a straightforward fit on your X166. Give the breaker your registration and engine code to ensure they pull from an X166 donor vehicle.

No — petrol and diesel turbos are engineered for entirely different engines and combustion systems, and they are not interchangeable under any circumstances. The GLS range includes both petrol engines (such as the 450 and 580) and diesel engines (such as the 350d and 400d), each requiring turbo units specific to their engine code. Always confirm your fuel type and engine code with the breaker when requesting a quote.

Some modern Mercedes turbos incorporate sensors or actuators whose calibration may interact with the engine management system, and whether coding is required on your specific GLS is something you must confirm with the breaker against your registration rather than assume either way. This is not something that can be stated as a general rule, as it can vary by engine variant and production date. Ask the supplying breaker and your fitting garage to advise before you buy.
