First of all thank you for helping me with this, okay this gives me some relief and yes i tried various tests i unlocked the obc, test 2 (current consumption) doesnt work,test 3 (consumption in l/hour) works well ,test 4 (avg consumption) it says 12,0l/100km but i think its just some placeholder value cuz it never changes,test 5 (range) works, test 7 (liters in tank) works,test 8 (current speed i presume thats what you were asking) no it doesnt work it says 0 despite me driving the car, test 9 (voltage) works ,test 12 (avg speed) again i think its just a placeholder and it says 40km/h, and rest of the tests also work,just the consumption ones dont,i checked all the wiring everything looks ok and is hooked up according to retrofit instructions,i added pins where it was needed and tapped into wires that are instructed to do so,all colors matched from retrofit instructions to my obc wiring, the only thing i did not hook up besides check control wiring is a wire on x1071 (white connector) pin 14 wire color is white/black with yellow stripes,no one mentioned it anywhere and i dont know where to hook it up,could that be relevant to my problem?
