your VIN isn't new to the list but it does indicate it is Ebony.
The VIN isn't going to show much except build date (not sure of how to decode this one) and that it is a true RS6 (WUA versus WAU) and that it was slated for the USA (904xxx thru 905xxx).
The option list is in the trunk, IIRC, in the spare wheel well... but it is a bunch of jibberish.
There aren't many options:
Nav,
Carbon, wood, I think there is another here,
Warm weather package (solar roof, sun shades in rear door panels, rear deck sunshade)
SE exhaust,
Exterior color - with some exclusives,
Interior color,
I think I am missing one or two...
