Battery terminals ok? I had a D2 do something similar when the positive terminal was loose. That blew up the alternator though.
How about that bolted terminal in the footwell that's problematic? Does it have a main power cable feeding in to the electrics box in the passenger side like D2s do?
I'm not sure how you would test for a bad earth. The modules likely wouldn't be able to detect it since they would power down for a moment. There should be a main earth from the battery negative, but I'm not sure how thats done in the D3 with the battery module.
I'd also be searching for the main harness earthing points which are usually under the dash on the A pillars.
It does have a hint of 'nibbled' wiring harness though too.
Very odd.
