B9 S5 Sportback: Black Optics Part# ?

[ChrisJ79]

Hi 

I am planning on buying a pre facelift B9 S5 Sportback and would like to swop the chrome grill, the front bumper vents and the rear diffuser for gloss black parts that were available in Europe and the US. I want to use genuine Audi parts, not a wrap or reps from eBay.

I can see all of the parts I need available on LLLParts but there are multiple part numbers all apparently for the Dark Chrome Matte/dark Chrome high-gloss finish and I can't figure out what is what!

Has anyone done this before and have the correct part numbers handy? Would this be something that my local Audi dealership be willing to help with?

Any help gratefully received!
