Okay, I understand. I'm actually someone who usually drives between 1500 and 2500 rpm for about 75% of the driving time... somewhere, those 4.xx liters have to come from .
I'm going to try a gentle, software-based approach for now.
For VAG gasoline engines, I reset all the learned values to zero using the code 01-10-000. Does the same procedure work for the TDI engine control unit (ECU)?
