Hi sir; I’m kindly request to help I have a serious problem of EDC 3779. My engine is power engine of MAN engine of 720KW. I follow all your steps. I changed all injectors, fuel pressure limit valves, pressure sensors, fuel pump - and others. If you can please help me and give me your contacts to contact you!?
How did you actually undetstand that the measuring unit was faulty? 3779 fault appears when the unit gets 10% or more load during low idle, which means huge overflow rate the unit can't manage with. Normal load rate for the measuring unit is about 1-5% during low idle. First of all you should measure the overflow from injectors, normally it's 50-80 ml per minute on low idle. If it's ok, then you test the rail overflow valve, it should be fully sealed. Only then you check the inlet connectors, but usually the have no problems. If you found no trouble in those things, then you should test the high-pressure pump on the test bench. As a matter of fact the problem is in one of the named things, if not - only then we can treat the measuring unit as faulty. But in 99% instances faulty measuring units are consequence, but not cause.
Hi, I have a problem with MAN TGA 18310 2002 d2866 engine. throws error EDC 638-02. when it turns on the error, the engine shuts off and the pump starts to rattle. The pump was taken to the mechanic, he says it's fine. is there anything that needs to be checked
Hi my friend, maybe you can show me where the man tga 2005 fuel shakes are, thank you so much hi my friend, can you show me where the Fuel Sprays of Man tga 2005 are, thank you very much
sir nagawa ko na po lahat ng procedure niyo kaso di pa rin po nakuha..from 2006 bar limiter bumabagsak sa 862 bar..pag tinaggal ko ang socket ng limiter valve balik siya sa 2006 bar..ano pa po kaya pwd gawin?
Hi Sir.ZBR 04401.Motor central lubrication system. Check the motor and electrical wirings of grease pump motor.located near cabin lift cylinder.near the right side front wheel.thanks
Hello sir in the fault alarm edc 03781.most of the trouble is in the metering unit.metering unit is to control the fuel pressure in the rail.but you said you already changed metering unit and pressure sensor.please check the current supply sir
Sorry sir d kita nareplayan dito.bz kc lagi.don sa comment mo na tinatanong mo fb ko may reply ako doon.baka sir d masyado mahigpit yong locknut na nagpupush doon sa fuel pipe connector papunta sa injector.check nyo muna yon isa isa.kung nagpalit kayo ng injector dapat isinama nyo na rin palitan ang metering unit.
Korek sir kc ang nagigibg sanhi madalas ng pagkasira ng metering unit ay maruming fuel at may halong tubig.kahit sa injector kadalasan dito may tubig ang diesel
Hello sir,sensya na late reply may nilakad kc ako ngayon.bali sa experiece ko dito edc 03778 hangang 0381.halos lahat ng yan ang problema ay nasa metering unit.kc ang trabaho ng metering unit ay icontrol ang fuel pressure sa rail.kapag nagmalfunction ang metering unit.magbabago bago ang pressure sa rail.
Bali ang ibig sabihin ng fault code na yan sir.EDC 03780 rail pressure:high controller output when idling...and ibig sabihin naman ng -01 ay TOO HIGH try nyo muna buksan ang metering unit para malinisan at mamasundot na rin yong check valve sa loob baka nag sstuck sya minsan.check mo link sir.thanks ingat jan kabayan ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YD_G9ogQCgQ.html

Sir.. magandang araw po.. paano po malalaman ang code? Wala kasing lcd ung man truck namin.. pero almost same ang situation, low power.. biglang nababa ang acceleration.. thanks.
Good Morning brother i have one MAN vehicle TGS Its showinv EDC 03779-01 code when this code showing engine reduce its power if vehicle loaded its code showing soon if vehicle without load its code showing after some time I replace all sensor and valves like meaturing unit ,rail pressor sensor ,return valves every thing Now i thknk its having problum in fuel injectors but before that i need your suggestion
I ideling position if we left start vehicle of if we give extream accelarater we not showing any problum but as we start moving on that time its shows problum
Hello sir good day,that trouble was also happened in my 2 units here.even i replaced the metering unit same problem still come after few hours of running i was replaced the injector and the engine is now good
@@jlcworkshop Thank you brother for your early replay actually i also have a doubt o injectors so today I replace injectors with new (complete 6 injectors) and then make a road test approximately 20 kilometres vehicle not showing any problem when i connect loaded loaded water tanker with it after 7 to 9 kilometres again vehicle showing same problem
@@jlcworkshop Подскажите как вычислить какая из форсунок неисправна? Если проводить тест с обратки на объем топлива это понятно, хотя у меня в норме 60, на нагрев электромагнитов с помощью сканера не помогло
Hello sir, EDC 03778-RAIL PRESSURE:LEAKAGE IN OVERRUN CONDITION.the engine has no power and hard starting. first,we need to replace the fuel filter,cleaning the fuel lines,check the injectors.and also replace the metering unit.
Hello sir.your engine is BLOW BY...happens when the internal combustion that occurs in your engine's combustion chamber forces contaminants such as air, fuel and moisture past the piston rings and into the crankcase.
Hello sir,good day.there are many posible faults if the malfunction engine control unit seen in dashboard.so the best solution is to scan using a computer to know the exact trouble..but can also do the simple things.replace of fuel filters,and check the metering unit.thanks
