I've got a silver s-line grill you could have mate i'm not gonna use it, just need to buy a badge of ebay or the dealer. Can post up photos tonight if your interested let me know.
I'd keep checking ebay normaly have an s-line bumper on there, i can only see that one at the moment (posted link). But no pre-face lift grills only two 09 ones.
As
Blazin and
Kaz said the photo
Smudge Don posted is an Sport or SE model, back in 2005 the S-line, Sport, SE and Standard all there bumper were all like that in till 2006 when Audi designed the S-line bumper which blazing has put up.
I could go out and basically buy a stand bumper and put an S-line grill in and it be an old style S-line bumper. But its worth waiting around for the proper S-line bumper to pop up. Remember Sport SE and standard have 4 vertical bars under where the grill rest's in the bumper, S-line has 2 vertical bars as you can see from the photo.
Hope i was able to help and good luck with the search
