Really need help with 2011 X5 35i

[MatHL]

Hey guys, i'm new to this forum and i've been having crazy intermittent issues with my 2011 X5 35i. I did some searching on my own but help from the community would be greaty apreciated. It drives great (so fun to drive) until I have the following idrive notifications:

-Malfunction in transmission
-Chassis stabilization malfunction
-DSC and xdrive malfunction
-Gear selector switch
-DBC malfunction!

Obviously, when this occurs, the car goes into limp mode, rough idle, or simply stays in park. All or several of these errors appear at the same time so i'm guessing that they're related. On rare occasions the wipers will also start and they cannot be stopped until it does by itself or the car is turned off. I heard that this may be caused when the ABS is having issues.

I bought a Launch X431 BMW scan tool and noticed that most of the codes are from the modules not being able to communicate (no message, communication fault, connection interrupted, etc). When looking at the data stream of the modules individually, they seem so have the correct voltage (14.5v), but goes to 0, then back to 14.5 multiple times every few seconds. This seems to be the case with the rest of the affected modules as well. When looking at live data, it will show a reading, then n/a, then back to the reading.

So basically it seems like my issues are all related, and that they lose power/signal intermittently which prevents them from communicating properly.

Here is a link to my diagnostic scan:

Any help would be greatly appreciated!

How old is your battery?

Battery was tested and is not the culprit

I had the same exact codes almost 10 years ago on my E70. I checked some of the fuses so that maybe a good place to start.
