will try and and get back

No did not work

next time you need to explane litle more how did this happen and what actualy wrong with your cas so we can help you sort it..if you can comunicate with modules make programing with autohex and vin will be corected under coding part..coruption will be sorted also if is the case..try this first

No did not work

Ok.. did not work we all have magic bal to gwes what did not work?what did happen? where did fail?how car espond? com one mate let be resonable.......

do cas firmware and restore it back mostly issue will be solved

write another eeprom and flash to the cas and do steps for cas replacement.

just to let you know how I went forward i hope it will help some one in future ,

e84 with working dme and key dead cas
Since i did not have a donor cas with working key. I borrowed a car with same specs made a key in key position 7 , read this cas eprom and flash (with vvdi prog) wrote it on the dead cas and changed the vin in the cas using the advance option (cas replacement) and then read the dme isn and wrote it to the cas
It worked

thank you all for you input hope this helps someone

if it is showing as different model that means fa not correct.did you restore FA from frm to cas?
dsc warning you can resolve by doing test plan in istaD,it happened because you connect cas with a different VIN.

The normal steps for the replacement of CAS (when original CAS is dead)
1. Get a working CAS with valid key
2. Read DME ISN and write it to CAS
3. Restore FA from LM to CAS from FA manager
4. Change VIN for CAS from advanced option in CAS replacement
5. GO back to the main menu in software
6. Start again with coding/programing
7. DO coding for CAS

make sure you followed all steps above
