so, for better or worse, my drivers side panel is pretty much the same (although the relays are blue strangely enough).
I looked for the control unit part number for my vin WGNC34 102488, and it returns part not found, ie there is no part# 31036 for my vin.
maybe post or pm your vin to chook or myself, something strange here.
also, chook, i was not able to find diagram 310-A2 as shown in your screen shots....section 310 goes to 310-b1 and 310-b2 for my vin?
