Help with hpfp error . E84 , 2.3D (4560)
Hey guys !
I am not exactly fluent in English , especially in all this technical terms but ill try . I bough E84 2011 2,3 D. My wife drowe it for a week and then going on the highway she had put full throttle down and got Engine Fault ( fuel engine power no longer available.) ( 4560 code) So basically High pressure fuel pump died it let metal shavings in nozzle and whole system . After repair , car seemed to work fine but when i tried to put peddle to the metal its again giving us Fuel pressure fault . Nozzles where restored , HPFP was restored , New Fuel pressure sensor , new Rail pressure sensor, new rail pressure regulator , new HPFP sensor , New fuel tank , all tubes where cleaned out , new fuel filter was installed , Pump in tank was also cleaned out . EKps Fuel pump control unit is replaced and coded ( e61) My friend/ mechanic thinks the problem can be in EKPS ecu ( , Rheingold Bmw diagnostic shows pressure of 3.9-4.2 is it normal ? Why does specificated and real revolutions in tank do not match , and why dose it give 4 bar pressure. If anyone got any clues it will be huge help! Again sorry for broken English |
