Hello! In advance, I am a Lupo newcomer and generally not a car expert. However, I recently bought a Lupo 3L and only after that I learned how “rarely” these were converted to a manual circuit. And just one I could buy cheaply. I fell in love with the vehicle and we are now in the familiar phase. In the car I found a schematic which is probably for the motor control unit. Can you tell me exactly what this schematic does? And where the “button” could be in the vehicle?
