CD9D [AND 11 other "Message"/ Communication Fault Codes]

BUS faults (loose/corroded connectors/wires) can prevent proper communication between Modules (your 335i has nearly 20 different Modules). CAS Module cranks Starter via KL50
IF it receives signal, VIA K-CAN BUS, that AT is in P/N. EGS sends that signal to JBE via PT-CAN bus, and JBE sends signal to CAS via K-CAN bus.
I'm NOT familiar with MHD, but I presume that is what ScreenPrints show?
INPA or ISTA would tell you if CAS is receiving P/N signal from EGS. When Starter will NOT Crank engine:
1) Do you see "P" or other gear selected displayed in Lower Instrument Cluster Display?
2) Can you press Brake (Ignition ON) and move Shift Lever from P to R to N to D?
3) Does Lower Display on Cluster correctly show Gear Selected?
