BCM2 8k0 907 064 KH      0681

SW 0681  is secured BCM, and you need use option for Adapter /Solder  and can not read D and p flash like old one
   
now if data lost , you can buy any compatybile BCM2 and match all wiith ODIS online  to restore immo, and then you can process add key via Xhorse devices
from Secured BCM2 you not able to read P and D, only immo can be extract
