Hi. How do you connect the new ecu to the car and connect the Vag or Vcds tester etc. Is the ecu connected? After Bdm he has to play ecu. You have the Ecu of course with the same HW:

Fasten the ecu to the car and see if the VCDS connects to the ecu. How to do that, connect galletto or Bdm and read ecu on the BDM table. No boot mode. Full bdm, old ecu read the same full bdm and load it with the same programmer.
