X5 E53 M54 No Crank Just Clicks DME code 80

[Animalmother]

So back in October my x5, e53 m54 140k miles, was in the grocery store parking lot. Got in to go home and No Crank No Start just a few clicks. The instrument panel lit up, lights worked but No Crank. After towing it home I retrieved the codes and got DME- 80 : EWS transmission/ communication parity. My battery was reading 11.9v and was nearing the end of its usefull life so I replaced it. Using Launch x431v I did EWS DME synchronization. In live data mode the EWS appears to be functioning and communicating as it should. The only key I have left is the plastic valet/ wallet key. One thing I found odd was, the key number the system was reading in live data mode was key #1. I would think one of my lost diamond keys would register as key #1 and the plastic key would be key #3 or #4. It's been my experience that starter motors usually give you a heads up before they fail completely. The location of the starter makes it difficult to test directly using a multi meter. Is there a way to access the terminals on the starter/ solenoid without removing the intake? Assuming the starter is functioning properly where should I look next?
