Unused plugs are common on newer cars. Cars come in many specs and for many various markets. It would be uneconomical and a logistical nightmare to produce different wiring looms for all of the variants. The spare parts inventory alone would be huge. 
that said, I can’t say for certain that this is the case here. I’ll have a look at my D1 when I get home.
