Question

Hello. I have a Man TGA 360 2003 and a problem with the engine. In the morning you have to shoot for a long time for it to light and it does not work evenly at idle speed. Maybe someone had a similar problem? The errors that are displayed are:
Edc 03051 - 03
03047 - 03
03048 - 03
03049 - 03
On the computer, it displays what is in the picture:

Any errors related to the rollout test. First try to turn the ignition on and off 5 times. The problem arose overnight? This is the D28 regular pump?

I have already tried with the key and it is the same. it is on an ordinary pump today, when I turned it off on a warm one, it was a problem to start it as if the fuel would come back from the pump or something like that

Errors have started to appear for some time after a long drive, when I turn it off, sometimes even the errors go out, but not once, but it works unevenly as if it would run out of fuel more than once

Check all electrical cubes on the motor from sensors, pump, computer, see if computer connectors are not oiled. The driver could have failed, unfortunately.

Where is this driver located?

Chavez · Answer

On the left-hand engine.

I forgot to mention the EDC main relay, next to the fuel filter housing, it is also worth checking (although its defect would spit another error) and check the EDC fuse under the plastic cover on the engine.

Oh, well, today I will check because his speed is so flawed that it is impossible to ride a jerk at idle speed

signals incorrect cables or fuses / relays finally computer.

I was with a mechanic, it turned out that the pump is jammed in the 3rd section and the valve that holds the fuel fell down so that it does not return to the tank, but after replacing this valve, it did not improve too much

Hello, I have a similar problem, the edc errors are identical
03051-03
03050-03
03049-03
03048-03
03047-03
I checked the wiring of the edc relay, the injection pump was replaced and the man still did not start. Please give me a hint where to look for the reason.

piotrek_brt · Answer

Hello, buddy, I managed to fix it Man smokes now from the arrow, it turned out that the valve on the injection pump at the fuel pipe did not hold the fuel and it returned to the tank and it was hard to light it then it started to walk unevenly, it turned out that one section was jammed on the pump and the injections went go to work and now everything is ok
