Hi Marcin
My DIS came from a 2008 A8 and I have the MPH readout , it didn't have ACC.
Its a fab upgrade and really lifts the whole driving experience.
As an added bonus my clock now works. For the first time in at least 18 months when I got in the car this morning I didn't have to reset either the time or the date. On the downside I can't use it as an excuse for being late anymore, but a price I happily pay.
