I got 2007 BMW 335 with MSD80 that is bad, replaced it with MSD81

Read 32bit ISN from MSD81
wrote that to CAS3 with ACDP 
Car throwing 2F49
After a while I realized CAS shows only 4bit ISN for DME


Can anyone help with this ? or any idea on best resolution ?

Short ISN it’s EWS3, 32 bit it’s EWS4, need conversion CAS, you have CAS3 with 0L01Y, I think need CAS3 with 0L15Y, I’m pretty sure that exist CAS3 0L15Y EWS3 and 4, but no exist CAS3 0L01Y with EWS4

Here you have dumps to CAS3 0L01Y with 32bit ISN. ISN is provided in a file, so just decrypt eeprom with provided ISN, change ISN on the one from MSD81 and it should be all good.
