BMW 640d 2012 replace ECU

[mr G]

Hello everybody,

I have BMW 640d 2012. ECU was flooded with diesel and some diesel went in to ECU. Previous garage removed ECU and opened to clean it. Also they lifted the board and probably damaged processor. Now there is no communication with ECU (before lifting the board communication was ok). Then guy bring me damaged ECU, but I can`t read even in boot mode (totally bricked).

Get second hand ECU, I checked, but it was opened before aswell, just this one have communication. I read all data in boot mode just in case. Now problem is ISN. Question is what options are to read/write ISN to ECU? BMW explorer and Autohex are out of my budget.

Regards
