Hello Audi community!
There's probably a place to post this so sorry if my etiquette is poor and also lazy if this hasn't been posted before. I just went from a Mk1 to and Mk2 TT and i'm going crazy trying to figure out what this button does. I've ordered an owners manual and it wont be here until 6-8 weeks.
-Thanks!
