Hello. I have a problem with my v50 namely since I bought a car, on a cold engine there was a slight ragging when the car was warmed up, the problem disappeared. I drove like that for 8 months, but recently there has been an error on the motorsystem cockpit worth erforderl which resulted in throttling the engine when adding gas and stalling. On the computer it poured errors and the idle fuel pressure was over 400 bar. I changed the cr siemens high pressure valve on the pump and the problem with high pressure is not resolved, but when I start the engine after a night, the ragging is greater than it was before the failure. The fuel pressure on the cold is 280-300 bar and, as the engine warms up, it oscillates around 270-290bar by jumping. I learned that the pressure on an efficient system should be 280bar evenly without fluctuations. Anyone have any idea? I will add that volvo without dpf originally, the egr was cleaned although it was clean, the car has the power to fire from scratch.] Link [/url]
