Основная причина поломки механической части ТНВД VP-44

My name is Oleg. I am doing car repair. The VP-44 high-pressure fuel pump on the Audi A6C5 2.5 TDI V6 suffers from various ailments. But from experience I can say that there are practically no such sores, or in a small amount, if a booster pump is installed in the car in the tank, which creates excessive pressure in front of the injection pump, and this eliminates the possibility of air in the fuel. It is much worse if there is a pumping pump in the tank, in this case the high-pressure pump itself draws fuel from the tank, and if the connections are not tight, air gets into the fuel. Air in the fuel is like an abrasive - it makes shavings and these shavings are then riveted on the walls of the advance piston sleeve. These work hardens begin to scratch the piston and in the end it wedges in the liner and the advance does not work. As a result, the engine starts to smoke and the rpm does not rise above 2000 - 2500 rpm. Registration for repair is possible. I am in Belarus, Grodno.
