With Ktag, if your ori file is ok, then just flashing it will start the car.

Did you checked if the car starts when you opened the ECU before writing the tune? I had a similar issue with ed17c50 and the issue was that just one SMD capacitor was damaged during the opening procedure. Try to find a HQ image of your ECU and look for missing components, also looking for signs of possible damage to pcb tracks.

Thats right.
I took a closer look at the circuit board with a magnifying glass and saw that a resistor looked strange. When I tapped it lightly with my finger, it then fell off.

I then simply soldered it back on and now it works without any problems. So it was a hardware problem. the Stage 1 software from scoc runs wonderfully without any problems. Many thanks to all for your help.
