Problem with bmw MS45.0 ecu

[serastif]

Hello,

I had to change my ECU MS45.0 5wk93018 on Bmw E60 520i M54b22.

I bought a used ECU with the same references.

I bought the MS45 Quickflash software to flash the fullread and mpc files I had saved to my old ECU.

The quickflash software detects the ecu well. But when I start the write procedure, the software cuts out.

I specify that I do this manipulation by the OBD socket with a suitable cable.

After that i tried to sync with ista the cas and ecu but ista returns ecu not accessible.

Does anyone have an idea on how to inject the original .bin files into the ECU?

Thanks for your help

I have tried the same, and it will read fine, but not write..
So i used ktag to swap files, and thats it..
do you change your ecu because of RAM faults?....

hello pal
first OF all writing on MS ecus need continues 12+V in advance to write and if you lost connection with your ecu in the middle of writing you need to do it with the KTAG and its 50%50 if that didn't ruined your ecu anything you need I'm happy to help pal if you didn't fix it yet
