The Mercedes-Benz OM607 is a 1.5-liter, four-cylinder turbocharged diesel developed from the Renault K9K engine architecture for Mercedes applications. In the original 2012 A 180 CDI (W176), the OM607.951 combines common-rail injection, a timing-belt-driven camshaft, a variable-geometry turbocharger and a diesel particulate filter. The same Mercedes engine designation also appears in documented A-Class, B-Class, CLA,…
The Mercedes-Benz OM606 is a 2,996 cc inline-six diesel engine with a 24-valve cylinder head, indirect prechamber injection and both naturally aspirated and turbocharged versions. It was fitted to E-Class, S-Class and G-Class models during the 1990s. Although the variants share the OM606 designation, their fuel-pump control, intake arrangements, vehicle installations and diagnostic systems are…
The Mercedes-Benz OM605 is a 2.5-litre, five-cylinder diesel engine used in selected C-Class and E-Class models during the 1990s. It combines a 20-valve, twin-camshaft cylinder head with prechamber fuel injection and a Bosch inline injection pump. Mercedes offered naturally aspirated versions in the W124, W202 and W210, and turbocharged, intercooled versions in the W202 and…
The Mercedes-Benz OM604 is a naturally aspirated, four-cylinder diesel engine with a 16-valve cylinder head, chain-driven overhead camshafts and electronically controlled Lucas EPIC fuel injection. It appeared in selected W202/S202 C-Class and W210 E-Class diesel models. Two displacements were offered: the 1,997 cc OM604 D20 and the 2,155 cc OM604 D22. The distinction between an…
The Mercedes-Benz OM603 is a family of inline-six diesel engines used in the W124 E-Class, W126 and W140 S-Class, and selected G-Class applications. It combines indirect diesel injection, a single overhead camshaft, a cast-iron cylinder block, and an aluminum cylinder head. The principal passenger-car versions have either 3.0 or 3.5 liters of displacement, with naturally…
The Mercedes-Benz OM602 is a family of five-cylinder diesel engines used in passenger cars, G-Class models and commercial vehicles. It includes 2.5-liter and 2.9-liter versions, naturally aspirated and turbocharged configurations, and two substantially different fuel-injection architectures. The full 602.xxx engine number—not simply the OM602 family designation—is needed to identify the correct specification and repair procedure….
The Mercedes-Benz OM601 is a family of four-cylinder, indirect-injection diesel engines used in passenger cars and light commercial vehicles. The family includes naturally aspirated 2.0-, 2.2- and 2.3-liter versions, plus the turbocharged 2.3-liter OM601.970. Applications include the W201 190 D, W124 200 D, W202 C 200 Diesel, T1 and T2 vans, first-generation Sprinter and W638…
The Mercedes-Benz OM617 is a five-cylinder prechamber diesel engine family that appeared in passenger-car applications in the 1970s and evolved through both naturally aspirated and turbocharged versions. Verified application evidence begins with the W115 240 D 3.0 and extends through W123 and W126 models into the mid-1980s. OM617 should not be treated as one fixed…
The Mercedes-Benz OM616 is a naturally aspirated four-cylinder indirect-injection diesel family used in Mercedes passenger cars, G-Class models and commercial vehicles. It should be treated as an engine family rather than as one fixed specification: individual variants such as 616.916, 616.912, 616.936 and later commercial versions differ in displacement details, output, compression ratio, installation and…
The Mercedes-Benz OM615 is a naturally aspirated, four-cylinder prechamber diesel engine found in several W115 and W123 passenger-car applications. The important distinction is the suffix: 615.912, 615.913, 615.940 and 615.941 do not all share the same displacement, output, compression ratio or service configuration. The verified passenger-car versions divide into 1,988 cc and 2,197 cc engines….
