i need help BSI Alfa 147

[tirnanic malisa]

Hi guys
I used UPA to read MC9S12DG256 so that I can program a new key.
The car had 2 keys.
I wrote a new key in the eeprom than i wrote that file in the BSI.
Then I returned the BSI back on the car and when i tried to start the car it didnt recognise any keys, like they were lost.
I went and read the BSI again and all the keys and ISO code were gone.
I tried to return the original file back in the BSI but stil the same, the car doesnt recognise the keys and the ISO code is gone.
Again i tried to read the eeprom, but the file was diferent from the original, and every time a write the original file, put it on the car and try to read it again the file is always diferent. Its like the moment i put it on the car it loses everything.

Has anyone had this problem before.

THANKS

I read/write many times with upa but never had problems. Try to read dump after write and compare if it is writed ok.

Sure dump returns mod with fault code you tested the coil?

I did.
Every time i write the file a check if it was writen ok and it is.
But after i connect it to the car and then check the eeprom again, it isnt the same

The coil is ok
The car was working fine before the writing.

Looks like hardware fault. Buy used bsi, write ori dump and test if the car is working. Then make new key with pin, don't make changes in dump.
