Isn from gearbox is ok
So you need to read isn from egs in factory mode and write in your dde/dme

You have to read ISN from CAS 4 with the working key but from some reason you cannot do this with Autohex.... but there are other solutions. I asked them to implement this many times but...

ISN between CAS and EGS will be different. EGS ISN will not help. He need to get ISN from CAS itself.

AutoHex II BMW Diagnostic Software Version 1.0.66

A new release has been made for Autohex software ,the only software which enables users to 🧨read and reset ISN from EGS 8HP from E, F & G series of BMW🧨. This brilliant function will allow users to get ISN from transmission which will help in case of replacing DME, FEM/BDC even when original controls are not available,key programming etc. From this update as we promised earlier all Autohex Packages with EGS reset option can reset EGS from 8HP E series on bench which was missing on previous versions. Please check the link for more details.

MICROTRONIK..CAN YOU EXPLAIN THIS FUNCTION PLEASE?

Initially we misunderstood that it was same ISN for EGS, but later on with further study we found out that there is different sync between DME_CAS_EGS which need to have same ISN. Its like have 2 ISN for EGS we are reading the one in factory mode which is different from DME-CAS so cannot use that while replacing ECU or programming key.

..so still you cant write donor ISN to CAS4 since its different to EGS's _ should have no effect, technically

yes that is right but in that case the original key will stop working that's why we don't recommend it.

you can match the ISN between ECU and CAS and reset EGS also need to program new key in that case.

Okey meaning it asks you the donor ECU ISN not that it gives you a generated ISN
