I noticed you've not had any replies - have you had any other joy on the subject ?
Ive got the same problem - button on centre console and on steering wheel plus gizmo in glove box for disc and 2 SD card slots but not activated in car - I've been quoted from 2 separate main Audi dealers of £1500+ and £1700+ !!!
Sounds crazily expensive considering it seems all to be there
Hi to all , just returned to the marque - I have previously owned A3 , A4 and A6 models but I've just bought myself a TT . It's a 2017 with only 12k miles so shouldn't have any serious problems yet but I've joined for tech and spec knowledge
