Strange behavior, Kess V2 and Golf V edc16u

[Fabiuz]

Hello all,
I have a problem with a Golf 5 1900 TDI 105cv Bosch EDC16U.
The ecu is original and will advance that a galletto v50 the law.
I can not do the id and during operation the power goes from 12,50 v to 2v in their computers.
I would like to try to use the blue cable or to vary the pull-up resistor.
Someone knows how to explain well the use of I'm blue wire and where and how to use R, how to connect it so
Thanks

Make sure to check your tool if you need to review the hw

The Ecu simple as that. As recommended by passion for engines, controls the hardware.

What I had thought as well I of the hw.
But I'm the blue wire that is from the extra voltage, I know to explain the usage?
Around it is a law that is connected to the Kline for providing an extra current, but if I connect to pin 7, I'm doing a loop.
namely, already the Kline hopes to connect from the obd at the kess...

It only serves to keep the 12V fixed by the bat to the kess

[Fabiuz]

I put the extreme of the blue to a 12V battery and the negative?
The same cable you use for the R pull-up?

Hello
Try to change the encoding of the setup of the reading of the ecu, k-line, can, velocitta, etc. you have to work.

I try and tell you
