The weight of the F9Qt engine according to the catalog is 172 kg. The engine number F9Qt is located at the junction of the block and the gearbox. The fuel system's Bosch fuel pump is very reliable, but on long distances, it is prone to leaks and air suction due to loss of sealing. The seals in it age and deteriorate. Electronic control unit malfunctions and wear of the plunger pair often occur here. Turbocharger: Saving on oil or rare replacement of the air filter leads to turbine wear, which can start oiling as early as 150,000 km. This is a very common problem here. Overheating: All engines of this family are afraid of overheating, and the gasket here often breaks through. The main danger is that sooner or later, the cylinder head will crack due to high temperatures. Other weak points: These engines are also prone to oil and coolant leaks, especially from the oil separator, contamination of the EGR valve, and regular electrical failures due to weak wiring.
