Tool works for me. I ended up cloning my original ECU and the doing the immobilizer off on my original eeprom, then flashing to a new ECU.
I was trying to not open up my original ECU and only modding the eeprom on the new ECU. This did not work unless I modded both the flash and eeprom. While the car started, it gave throttle body errors. I don't know why this is the case but my Newby guess is my eeproms from the new and orginal ecus where somehow mismatched. I thought that once immo offed, the eeproms would be interchangeable but appears I was wrong.
I was doing all of this to: (1) have a spare ECU to tune without fear of bricking it and (2) be able to use a spare key that I bought off ebay and had cut to match. Car only came to me with one key and dealer wanted about $400 to provide a spare.
All seems to be working but the spare key, while functioning, shows "safe" in the MFD. Now trying to figure out how to get rid of this message in the MFD.
Sorry if this digressed from the thread topic but hoping to help others along the path.

I think it's normal the "safe" on Mfd with unpaired key. The dash does not recognize the key, but ecu let engine starting, because is immo-offed

Thanks. Trying to adapt key now. Is the security access code provided by this tool the same thing as the SKC?

Also is this a Vw or Audi? Apparently Audi ecru is a tougher nazi "9.1"
I know mpps v16 also works well for Audi 9.1 I've been told via obd

This is a 2006 Audi A3 w/ immo4c. Thinking immo4c needs the transponder pre-programmed by Audi or least that's what I've been reading. so I'm gonna just secure my good transponder inside the steering column and call it good enough for getting rid of the "SAFE" in the MFD when using any key. Wouldn't even had to immo-off the ECU if taking this approach.

It does need to be pre-programmed, but not necessarily by Audi...  |

Thanks @technic
Are you still working on the tool?

I hope the question ist not stupid and hope someone can explain it.  I read eeprom of MED9.1 (1K8 907 115 F) via BDM, result = 4kb. If i read the same eeprom via Galep, result = 2kb. According to datasheet https://www.mouser.de/datasheet/2/389/m95160-a125-1156156.pdfthe memory array is 16 Kbit (2 Kbyte) of EEPROM = 16 kbit / 8 = 2kb. If i split the 4kb file ($000 - $7FF) and ($800-FFF) the parts are identical. Why BDM double the content? |

I assume you are using a Ktag...? I think only tool development can explain why it double eeprom. Some other tools read correct size from MED9.

I use CMD BDM clone like the most people here, i think. |

Some tools just read it once but the protocol is clever enough to ensure both EEPROMs are written. Other tools will back up verbatim and read both in serial. |

From my understanding there just one physical eeprom type 95040 2Kbit (if I remember correctly) and the other 2Kb portion is inside microprocessor. Then my question is which tools can read both in serial? |

Could someone tell me how the eeprom checksum calculation is done in me9 95080?
Thank you:
Peter
