Hey guys!
might need a little help here!
I have that 2007 bmw 328xi I am trying to install a used DME on it (MSV80) but turns out to be way longer that I imagine.
Using AVDI, I have achieve to read 16 bytes ISN from original DME and second hand DME but not able to read 16 byte ISN from CAS. (can read the 4 bytes one easily)
I have read eeprom and flash from CAS manually, and I did found the 4 bytes ISN and 16 bytes ISN.
so changed the 16 bytes ISN but it is still a no start.
I did program the vehicle with ISTA-P since I now had many weird fault code in DME since the ISN reading procedure. I now have a DME which is up to date, and the VIN had been match at the same time... + no more weird fault code. just the one saying EWS manipulation in DME. try obviously to synchronize CAS/DME without success. (says ISN mismatch with AVDI)

you have updated cas3 probably so cant read by obd and isn encripted..try paste ISN from cas to MSV80 or read old ecu by tricore if posible and write to new one

The msv80 are notoriously difficult to read and write in tricore.
I've done a couple, but it takes at least an hour each. Including soldering pull up/down resistors, etc.
