hi everyone

i have a 2007 e90 325i PM1VH59050A159764 CCC idrive not powering up

ista code
- a731 jbe: supply, terminal 30g-f (can be cleared if i reconnect the battery n idrive will come back to life but if i let the car to go to sleep the code will come back n idrive won't power up)

- cf19 no message (wheel torque request) from the LDM, receiver DKG/EGS, transmitter(cannot be cleared)

whats been done to the car before me
-jbe & fuse box replaced from 9119447 to 9119444
-cas3 replaced with cas3+
-dme replaced with same module msv70
-frm3 replaced with frm2

what i've tried
-reconstruct the vo
-default coding jbe,dme,frm(no problem)
-default coding cas failed(ncsexpert error return coapi-2060 cas, c_c_auftrag_cas)
-checked terminal 30 relay(no problem)
-checked the battery(healthy)

everything else seems to work fine
