As someone mentioned earlier, you need to connect the selector latch signal from aux8 to the CAS module. If the car receives information via Can-Bus, it will allow the car to be started without this signal, only an error will appear in CAS and the gear on the instrument cluster.

As I mentioned earlier that connection is already done. Otherwise the car would not start.

This is not my work it is from Cantcu. But it will likely fix your problems.

"Car needs to be fully coded as an automatic (S205A in VO/FA) and the DME/DDE programmed using automatic transmission software to support torque interventions
CAS: AUSWERTUNG_P_HW → nicht_aktiv
CAS: ABZUGSPERRE_PLOCK_C6 → nicht_aktiv
CAS, E65 only: ANLASSERSPERRE_HW → nicht_aktiv
In some models CAS will throw a fault code regarding PLOCK. This is fixed by adding an extra ground wire on CAS pin 11
In some models, the RPM needle behavior will be erratic. Fixed by changing the value of DZM_DISP_RPM in KOMBI."

Please update the thread if this is any help.
