Have you tried the mad mod on the VagCom? It will get the voltage to the ECU. http://forums.nasioc.com/forums/show...&postcount=190
To get power to the ecu you will need to jump the pins inside the cable at the ODB end. It is shown in the pictures, the white wire from 2 to 9 and 1 to 7 if i remember correctly. The 02 ecu is kinda a pain.
