Hello friends,

For a Volvo generator SN D9A2A*7009172511, I want to swap a burnt Volvo Ecu 20814594 P04 with a second hand used one.
But before, I need to write Software ID= VP-127785 inside.
Can someone tell me
- where can I find this software and
- how can I use Volvo Tech Tool PTT version 2.7 or other tool to write Software ID= VP-127785 inside.

If PTT is not applicable which software (Kess, Ktag, FG Tech...) can do the job

If still not applicable, if there is a EEPROM or Flash component that I can swap between the both ECUs

This last solution is not the best as manything may happen while unsoldering and soldering the parts.

Best regards
