Volkswagen Golf 4 03/1999 1896cc AHFS 81Kw Diesel Error 17656 and pump postponed

[amen]

Hello everyone, I made a diagnosis of this golf, which was released in dtc 17656 "adjustment of the initial injection," that persists even after cancellation. With a diagnosis Delphi, I noticed that there is a function to check the adjustment of the injection, and is quite delayed. Now, as the cutting and distribution were not made at our workshop, I don't have the absolute certainty that everything is up to rule d art, but before disassembling, I would like to know if it's already happened to someone. I enclose a photo. Thank you very much.

The phase lai controlled?

maybe replaced the belt and not in phase as it should..

Phase seems to be ok, but not that of the pump, I think that I will have to act on the same to make it back in phase, but according to you, was done on purpose? I don't think is beneficial. And it is possible that each time you shut down in gear for this reason? It has no other errors.

Hello, that is on purpose or not, I don't think you can know.
The fact that you shut down in gear if the pump is out of phase, I don't know to say.
The 17656, is equivalent to the p1248, which could be a malfunctioning of the power plant, blown fuse, or the connections to the pump.
Not to neglect also the control of contamination in the oil.
