I also doubt that your failure to crank and valvetronic codes are related- thats just a guess but i cannot see a way to relate them off the top of my head.
Troubleshooting this (with your new DVM) is entirely doable - schematic diagrams/connector pin outs are available in ISTA-D. However, I’m away from home and have limited internet access and only my phone to access it with. So i cant help much for a few days.
I suggest dumb googling 2a3f, 2a77. There may already be some helpful discussion threads.
Just a thought, have you recently unplugged the DME connectors as a part of your investigations? easy to bend those pins putting the connectors back. Again, just a wild guess- the righr course here is to examine voltages at various points in the valvetronic circuitry

You have been immensely helpful, I appreciate the time you've taken to explain all of this to a rather dense individual such as myself lol.
I will do some more research and troubleshooting , and reply with results!
Enjoy your weekend, and thank you again for all the wisdom you have brought to the thread!

Upon further research I've found that cable is "B+ to engine electronics"

I have removed my battery and absolutely see the issue (pictured below). Unfortunately its not the cable as I suspected, but the actual terminal the cable connects too has broken!
Cable part = 6938504-03
My problem, what is it it connects to on the other side of the wheel-well? And exactly how screwed am I? The cable would have been a quick 5 min fix...
