AWD and DSC malfunction, Engine malfunction, DBC malfunction

[gregg3gs]

WTF. (UPDATE bellow)

2008 x5 4.8 with 85k on the clock.

Does any one know if my transmission is failing?

On a way to work driving the x5 and then system malfunction pops up, and car is not drivable.
Why would engine malfunction follow AWD and DTC malfunction?

It happened last week and I had a local BMW mechanic take a look at it.
Since all modules needed a Firmware Upgrade all they were able to do is software. After driving this thing for about a 150 miles the problem is back up.
Some of the old codes I saw (provided to me by mechanic):

DSC
5dea dsc: transfer case: temperature
6e83 dcs: tyre pressure control: interface
5d95 dcs: control unit, valve relay
6e7d dcs: sporadic undervoltage detectedby EMF control unit. Delete fault memory
5f77 dsc: Engine management: interface

EMF
601d dcs interface: signal invalid
601e dcs interface: signal invalid
6023 Control unit: faulty power supply
6041 message error from dsc control unit
d359 no message from EGS control unit, receiver EMF, transmitter EGS/HIM

DME\DDE
2d32 differential pressure sensor, intake manifold, plausibillity
2cf8 throttle valve potentiometer
2cf9 throttle valve potentiometer 1
2cfa throttle valve potentiometer 2
2a6b Valvetronic, power limitation
2d13 air mass sensor, rationality

Here are all the warnings (pictures):







UPDATE:

This problem was diagnosed to be a failing throttle body. The best part of troubleshooting this was that the throttle body would pass adaptation and not fail during this.
My final understanding of this problem and the troubleshooting of it is that; this problem can be generated by two devices in your x5. Those two devices are bad ecm and failing throttle body.
In my case it was a throttle body. At this time the SAV is at 114k and the issue has not returned.


Another UPDATE:

Some have troubleshot this to be a wiring issue as well.
