Well it is an RSA error, which ECUFix ignores by patching out the RSA routine. I believe some versions of WinOLS ME7 plugins do this as well, but I could be wrong.

So i tried flashing both maps several times, which was successful, but DTC can not be deleted. Car still wont start.

What are my options here? I have read many topics regarding P0601 and im still lost what to do next...

1. In boot mode write old eeprom( one you pulled out when there is no DTC)
2.turn off ECU
3. Again start ECU in boot mode and write ori flash
4.Turn off ECU, put in car and start

and then when you go to tune, use one and only one known good "checksum corrector" (i suggest me7sum as you will get the best support here). on ECUs with RSA, the different methods of "fixing" RSA (disabling using various code patches vs. self-signing like me7sum) will clobber each other in very unpredictable ways. using more/multiple tools does not make checksums "more correct."

Hello,

back from camping weekend with family.

Thank you for all the guides and help.

Im going to attempt to solve this today. ive never done this before but looks doable.

Ive gone thru ME7 EEPROM programmer topic - will give it a try. ( i should see death code in eeprom?)

Made a new map which looks clean in and out

any more advice - i dont have ori eeprom
