Hi
Did someone got problem with flashing 0CW unit to another software using genuine VCP??
I need reflash used machatronic unit 0CW300041  to flash that will fit to my car VW Golf CLHA with QRK. Old mechatronic is gone and not available.

FL_0CW300047R_5250_OVHJ_sw.frf
while attempting to flash there is an error about preconditions not fullfilled.
Hardware is: 0AM 927 769 E    CU5-072

The mechatronic is on the bench or it is mounted properly in the car with all systems connected ?

Tried with two mechatronics.

First one is instaled in car and had GEKO online immobilizer and VIN matched, but comes from another VW with 1.4TSI CZCA so thats why there is need to reflash to another SW.

Second one i got on bench and got full connection with VCDS or VCP diagnosis, only Can High and Low connected and +14V from stabilized power supply and GND. Should I connect terminal 15?   as 0CW are waked up with Can
Also this unit on bench is full complete unit dismounted from another VW and been never connected to car so it isn't locked.

Problem solved.
The main issue was i was trying to flash software that was dedicated to different hardware generation.
Mounted DQ200_MQB 769K TCU to car, made online immo matching and then ODIS E was able to flash new software with differenrt number needed.
Flashing on bench was unsuccesfull.

In general:
Immobilized unit can be cloned on bench but flashed only in car with immo matched.
