Bench read MED17.5.2 IM608 fail

Bosch MED17.5.2 read with IM608 and written using VVDI2 in parts adaptation. Read with 608 to get info. It does not have save then write so I used the same connection to write back to donor. Read afterwards and donor reads having the original vin cs and pin. Mac is same as donor.
This turned out to be a fail because the cluster has a 12 bit cs and I was only able to write back 6 to the
ecu. The cluster still says Immo active. Dtc have ecu not authorized still. Do Odis will have to code this one.
