Good evening from down under,
I wouldn't have a clue about this (Even if I could pull some luck out from under my couch!). But, if it looses bluetooth hardware and comes up with the same code....I don't know honestly.
As I always do, after a quick google search, it appears that the SNS part is a faulty sensor believing that too much current is coming in. Based on the apple support page I followed, the only way to fix this is to replace the logic board (Unless you take it to someone like Louis Rossmann who is based in NYC). The link to that page is: https://discussions.apple.com/thread/8248025
For now, it looks like your SOL on this. However you can use the same storage drive from your old computer. If you want one they run really expensive (1k aud!!!!!), or you can take a gamble and get this for 175 USD which is unable to install OS (I really hope it's a drive issue so you can slot your new one in). That link is below:
