Hi all, newbie here! , I have an Audi A3 2.0 Tdi 2010, from what I have read on the internet this uses the EDC17C46 ecu which I understand can't be programmed through OBD2 port. Using MPPS cable and V21 software when connected to OBD2 port and I select the A3 and "All TDI Bosch EDC17 X UDS" ecu and select the ECU Id I get the above information. Can any one confirm from the above information what ECU I have actually installed in the car and if I can actually programme the ecu with the setup I have? What does the "Authentication passed for programming mean?

Thanks in advance guys.
