Michael II: Insights and Perspectives for Everyone:-)

First of all, thank you, Michael II, for your posts with the target data.

Okay, here's the translation:

"Now, regarding the question I have a "Powerbox" from PSItuning, specifically an ATU for PD TDI engines, and I'm having a disagreement with my friend. As far as I can see from the publicly available schematics, only 5 wires are connected to the 8-pin connector (e.g., 038 973 121 in a Golf 2000). To me, it looks like 4 of those wires are for the solenoid valves of the pump modules, and one is used as a reference potential, meaning it's just for normal opening/closing control; nothing else. That's my opinion."

My friend claims that some data is being transmitted on one of the cables, but since we don't have an oscilloscope, we can't verify this. Maybe you know more.

Thank you, Hugo.

Hello,

I completely agree with you.
