Foxflash new user report: Got a new work table and power source, first test with new setup. Audi A6 C7 3.0tdi 160kW ECU EDC17CP54 Read ok on bench Write ok bench Checksum by tool. Adblue off. No problems, all good. You reset all adblue related stuff with diagnostic software. (I used launch) Then removed ecu from car, read soft from ecu, sent it to tuners, received modified file back, write the modified file back to ecu, installed Ecu to car, started the car and all the errors was gone, simple as that, no need to disconecct something, if needed they will let you know.
