Autohex was able to retrieve the 128SK from the second hand MSD81. It had to downgrade the CAS module, however it now says vehicle order is corrupt after downgrade. I tried overwriting it from data from LM. Nothing is changed. I attempted to write SK from MSD81 to original CAS, Autohex shows successfully performed. However when i check the CAS module, the original ISN and SK are still present in CAS. Nothing is changed. Car only cranks, but does not start, EWS anti-tampering faults stored. I also tried with a second hand MSD80, same results.
Please assist.
