Okay, I've given up;-(
After several unsuccessful attempts and measurement series, I'm now reinstalling the original potentiometer for the GOLF III and will build a waterproof box underneath the car.
The reason I switched to a GOLF V was because the potentiometer was moved inside the car. In my GOLF III, the potentiometer would get flooded after every time I drove through water, and then it would become defective.
If what you're saying about "1 Volt" is correct, then I don't understand the behavior.
I connected 10 kΩ resistors in series. The result was an idle rate of 10-12%, compared to the previous 8-9%.
Then I had a 10 kΩ resistor connected in parallel with the internal input impedance. This resulted in the system only delivering 80% of its power at full throttle. Nothing has changed regarding the idle speed.
Check. And that's the end of the tests.

Thank you for the feedback... unfortunately, I only just saw this thread.
Two ways immediately come to mind as to how this was likely made possible .
- Modify the fuel injection map in the engine control unit (ECU) to match the new requirements.
- Adaptive adjustment using an operational amplifier.
