Mercedes G-Class 350 CDI engine for sale

Mercedes G-Class 350 CDI engine for sale

Product Overview

For sale is a complete matched engine and transmission package from a 2018 Mercedes-Benz G-Class 350 CDI, recording just 38 kilometres — factory commissioning mileage only. The package comprises the 3.0-litre V6 CDI diesel engine, code 642.887, and the 7G-Tronic 7-speed automatic transmission, code 722.903 — both from the same vehicle, at the same 38km mileage, and supplied together as a complete, matched drivetrain unit.

At 38 kilometres, every component of both the engine and transmission is in factory-new condition. The engine’s V6 diesel internals, turbochargers, injectors, and all ancillaries, along with the transmission’s torque converter, valve body, multi-plate clutches, and all gear sets, have experienced no meaningful operational use. This is the closest available alternative to new Mercedes dealer supply for both units simultaneously.

Drivetrain Specification

About the Engine and Transmission

The Mercedes OM642 — engine code 642.887 in this application — is the 3.0-litre twin-turbocharged V6 CDI diesel that has powered the G-Class 350 CDI across multiple years of the W463’s production run. It is one of the most widely deployed and durable diesel V6 engines Mercedes-Benz has produced, fitted across the E-Class, ML/GLE, GL/GLS, Sprinter, and numerous other platforms as well as the G-Class. In the G-Class 350 CDI specification, the OM642 produces 155 kW (211 hp) and 540 Nm of torque — well suited to the G-Class’s demanding on and off-road requirements.

The 722.903 transmission is a variant of Mercedes-Benz’s 7G-Tronic 7-speed automatic— the torque converter automatic transmission that has been the standard automatic choice across Mercedes’ passenger car and SUV range for over two decades. In the G-Class application, the 7G-Tronic provides the smooth, progressive shifts suited to both high-speed motorway use and the low-speed, high-torque off-road driving for which the G-Class is specifically engineered. The 722.903 code identifies the specific calibration variant fitted to the G 350 CDI application.

The G-Class is one of the most durable and sought-after vehicles in Mercedes-Benz’s range — a platform with over four decades of unbroken production history and a combination of genuine off-road capability and premium road presence that no competitor has successfully replicated. Sourcing a 38km, 2018 engine and transmission package for this vehicle is an opportunity that does not appear commonly in the secondary market.
