I think the part # posted (earlier in this thread) for the socket cover was incorrect ..... (I just got my Depo Euros from importvision):

I ordered these parts at the dealership yesterday:

qty (2) - 006 545 80 28 - six-pin electrical connector, socket - $2.40 each

qty (2) - 009 545 30 28 - six-pin electrical connector, cover - $3.00 each

qty (2) - 003 545 26 26 - pin, connector (female pin sockets for city lights) - $2.80 each
