The weight of the D4HA engine according to the catalog is 214.9 kg. The engine number D4HA is located in the area of the accessory belt. The fuel pump is equipped with a Common Rail Bosch CP4 fuel system with piezo injectors, which is quite demanding in terms of fuel quality and quickly fails due to poor diesel fuel. It immediately starts generating shavings, which clog the entire system, including the injectors. Often, on a mileage of less than 100,000 km, a loud noise or rattling can be heard from the timing system. Sometimes, stretched chains can cause the noise, as their hydraulic tensioner has already weakened, but usually it means that the damping crankshaft pulley has failed and needs to be replaced. Typical problems, like any modern diesel, include clogging with soot and sticking of the EGR valve, limited lifespan of the diesel particulate filter, which sometimes lasts less than 200,000 km. Glow plugs are also often problematic, usually due to faulty wiring or relays. Other weaknesses of this assembly include the boost pressure sensor and the turbine geometry control shaft. By the way, the turbocharger itself is quite reliable and can last up to 300,000 km. Additionally, on engines from the early years, the cylinder head gasket occasionally blew at low mileage.
