Hi I have a 2011 x5 3.0 e70 40d been having issues with the car jumping and jerking while accelerating. Read the fault codes and it is showing codes CF77 and CF57 in the vtg transfer case also fault code CC95 in servotronic and also fault code C919 junction box electronics. I have tried Google for these but had no luck. Hoping someone is knowledgeable on here to help thanks

CF77 Message (Engine 1, 1D0): implausible signal or value lmv_84 Transfer box

CF57 Message (speed, 0x1A0) fault, receiver VTG, transmitter DSC vgsg70 Transfer box
CF57 Message (speed, 0x1A0) error, receiver VTG, transmitter DSC vgsg90 Transfer box
CF57 Message (Engine 1, 1D0): no message lmv_84 Transfer box
CF57 Multiple fault message 3 (low-level seriousness) for (EGS_EL, PT-CAN) from (CAS, PT-CAN)

CC95 No message (engine data, 1D0) svt_70 Servotronic

C919 No message (engine heat flow, 0x1B6), receiver JBE, transmitter DME-DDE jbbf70 Junction Box electronics

These I would suggest point at faulty wiring or a plug come loose, or full of crud/oil. They all point at loss of signals between the transfer box and engine computer (DDE) as they seem to involve the CANBUS.

Thanks for your reply.So you think I should probably take it to a auto electrician. I read somewhere about removing fuse 92 and since doing so the car drives fine but obviously have warning lights in the dashboard.
