The weight of the D4CB engine according to the catalog is 263.2 kg. The engine number D4CB is located in the front part of the cylinder head and faces downwards. In 2008 and 2009, the engines were replaced under warranty due to a fracture in the connecting rod caused by defective bolts. In engines after 2011 with Common Rail Delphi fuel pump, chip production was often observed. The most well-known malfunction of this diesel engine is the burning of the copper washers under the injectors, which leads to rapid carbonization of the engine with very sad consequences. Another common problem with this engine is a clogged oil pickup. It is advisable to periodically check it, otherwise unexpected bearing rotation may occur. The gas distribution mechanism consists of three chains, and the weakest one is the lower chain that drives the oil pump and balancers. Usually, when it breaks, the main timing chain also breaks. Other weak points include crankshaft bearings, hydraulic compensators, vacuum control system, variable geometry turbocharger, and EGR valve.
