maybe someone will be here to help me? i have two ecus with the same numbers 03G906016JA 1037377587. I don't know their past.

ecu n1.
Attempt to read with Ktag and BDM adapter.
Successful reading, I have 3 files (mpc, fls, eprom)
File previously modified by someone and saved on stage1. I would like to save the original file on it now and disable immo in eprom.
Attempting to write also after BDM - I get the message - "operation not allowed"

Only the attempt to save the compressed KTAG file (read earlier and undivided) was successful, but this is not a solution for me.

When you try to read KESS bench on the OBD using the OBD2 ID connector, it is also impossible to read, write, and recover.

Can someone tell me what to do to save the original file and then modify the driver after OBD ??


ecu n2
When I try to read as with ecu n1 after BDM I get the message "unstable connection. Check cable connections", nothing helps.

When trying to connect using KESS bench over obd2:
ID success
reading success
write - operation not allowed.


So I have two similar and completely different problems and due to the fact that I do it as a hobby, I am not a professional or an expert, I am asking someone for a moment of time and help. For sure, if only I can, I will repay the same, because I really do not know what to do so that I can save the original files on both drivers, which I can later modify on the car using the OBD2 cable.

thank you if someone takes a moment and shares valuable comments.

have a nice day


p.s i uploud files which i read before via BDM (ecu n1) and via obd (ecu n2)

Hi M8, if you are using slave tools.....may not be able to write unless master decode and recode to your tool.
Also file can have some kind of proteccion.
Regards.

i used master tool.

BTW I tried another ECU with such numbers and everything was successful so my problem was solved.

and now how can i save both ecus? is it possible ?

1. is modified by cmd... and "tune" :roll:
For best get proper Originale BDM file and overwrite, than do immo off or adaption.
2. Don't know you problem because is partial obd read..
