Audi interior seat colours leather/alcantera

[Grant-S4]

Hi Everyone'

Be gentle as this is my first time on a forum and any advise would be gratefully received.

I own a S4 b7 4.2L V8 cabriolet and Joined today as I'm looking for some advice on who can supply/repair the correct leather dye and alcantara fabric..! I've been told its a 2008 only colour.?
The leather needs dying in places and the alcantara bottom and back inserts need replacing as damaged/worn.

I've had a local interior trimmer trying but his supplier is not having much luck, the seats let down which is otherwise a very nice example of the Audi S4 Cabriolet.

Any advice would be gratefully received.
