i managed to write without error the immo off file.but i dont get one thing...i have a 8n0 906 018 S ecu..if i write the 8n0 906 018 A flash in it ( both are 29f400bb) , vag-com doesnt recognize the ecu anymore....why?
thanx in advance!
Do you Flash in boot mode? Try to write with boot mode. |

I have next situation I bought a spare used ME 7.5.10 ECU and I don't have its pin code, I know my original pin code from the ECU I have now on the car. If I install the spare ECU in the car and try to start - the immo will come on . In this particular case is it possible to read over OBD not in bootmode the content of 95040 chip with ArgDub tool ME7_95040 in order to decode the pin from the spare ECU
In other words:
Has somebody succeeded to read the content of 95040 chip with ArgDub tool ME7_95040 over the OBD port from an ECU not matched with the cluster?

I guess it's not possible. In order to connect through ODB the ECU should authenticate successfully with IMMO. |

Even if I'll remove the cluster fuse? I mention that I can communicate with not matched spare ECU with vagcom , it's possible to scan and show stored dtc's , I even erased the dtc's from this spare ECU without being matched to the cluster ?

As far as I know if the ECU didn't authenticate with the cluster you can do only several things with it (read DTC, etc) and the car can't work properly as well. In order to connect to the ECU in boot-mode or OBD (for reading and writing flash/eeprom) you should defeat IMMO or enter correct PIN code in ECU's EEPROM. Or just duplicate EEPROM into your new/spare ECU. |

and you think it could be done in boot mode or bench mode? bench mode is preferable over boot mode - I'm talking about reading EEPROM with ArgDub's tool

You can use boot-mode in bench. BTW I managed to read/write my EEPROM from HN-box only in boot-mode with the ArgDub's programm. How I did that http://golant.users.photofile.ru/photo/golant/96680328/xlarge/130404903.jpg |

"bench" is not a mode, it is the practice of connecting to the ecu on a workbench as Golant has shown (outside of the car). for these ecu's, you need to open the ecu and do a little dance to get them into bootmode, which is easier to do on the workbench, and is why the terms are frequently mentioned together. example: "bench and bootmode it" |

I thought bench mode is to have a harness, an OBD connector and a 12 V DC source to connect to the ECU outside the car but -without inducing the boot mode state of the ECU by opening the case and ground the correct pin- bypassing the cluster .
So did somebody succeed to read EEPROM of the ME 7.5 ECU with ArgDub's tool through the OBD port ?

Argdub's tool is hit or miss via OBD. I don't even bother trying anymore, I just bootmode. Reads in 1/10th the time and never fails.
But to answer your question, yes, I have used it via OBD on me7.5, and it has worked several (but not all) times.

Thanks very much Ddillenger for your very clear answer , the second question is if you succeeded reading the EEPROM through OBD of an spare ECU not matched with the cluster - reason not known pin code, or it doesn't matter so the reading can be done through OBD for both situations matched and non matched ECU's with the cluster?
Could help in this particular situation of not matched ECU - removing the instrument cluster fuse 11 or both fuses 11 and 15

It can be read via OBD even if not paired to the vehicle.

Thank you very much DDillenger , that's a very good news , as I don't want to open the ECU box and solder a wire to ground the pin in charge with booting mode of the ECU  I will do the operation this weekend and let everybody know the results, hoping to be a successful reading |

It can be read without taking off cluster fuses. |
