- The 245 hp version utilizes the BorgWarner R2S bi-turbo system. - The weight of the OM 654 engine according to the catalog is 168.4 kg. - The engine number OM654 is located at the junction of the block and the oil pan. - A known weak point of this diesel unit is the low lifespan of the rockers. - If you miss this problem, you will have to replace the camshaft and hydraulic compensators. - The Bosch CP4 fuel system with piezo injectors does not tolerate substandard fuel. - Intake channels in the cylinder head and valves quickly clog up with carbon deposits from poor diesel fuel. - As always, eco-friendly features such as EGR, SCR, and particulate filters cause a lot of trouble.
