Audi wheel paint codes?

Anyone know an online source for Audi wheel paint codes? Specifically I'm looking for the '04 RS6 code.

Hit several places, including a couple of Audi forums. Even a local paint supply place didn't have it.....

Thanks in advance

This won't answer your question, but a recent issue of the British mag Performance Car had an article closing out their long-term test of an RS6....I think it was. They experienced the same issue when it came time to "dispose of" their car....that is the paint on the wheels was flaking off. Also, pix of the nose of the car made it seem that the paint on the hood and surrounding surfaces doesn't stand up all that well either. Tho the car could have just needed a real good wash/wax.

All I could find is for a 2007-2009 S-6

The code is L1H7 Felgensilber Met.
