Car from 2005 130kW. He came to me with a problem of power drops. I diagnose him with a carman. At first it goes ok as cold (the owner said that not always). After light heating, when I take gas and add it, it has a total power drop. ESP lights up which in errors tells to check the engine but no errors in ecu. Parameters if there is no strength and I keep pressed the pedal into the floor is max.pmp pressure fuel, turbine pressure increases slowly from 1300mbar to 2000mbar but the car does not drive. When the car has strength, the turbine at 2150mbar captures up to 2000mbar. 145Mpa fuels. Egr clean. Throttle walks lightly. When driving with silted and pressed gas, sometimes something gives him a bounce and goes like a rocket, but just declutch and change gear and already lime. The car had a dpf dumped six months ago, physically and electronically. Since then, the customer has not had problems until now. I suspect the denso cr3 fuel system on piezaki. (Filling valve in the pump, control on the rail or injection) I am surprised by the lack of errors in ecu. What do you say?
