Just picked up 2008 A4 2.0T Q SE at the weekend.
Noticed when we got it home that the rocker switch at the end of the wiper stalk is gone (previously we had a 2003 A4). The manual shows it should still be there so that could imply that it has been removed only in the CAD models since the book is US/CAD.

After talking to the dealer, turns out that the previous functionality of the trip computer is gone (average mileage, speed, real-time fuel consumption, etc.). The only thing it displays now is distance to empty.
Not a major disaster but kinda annoyed about that because liked keeping an eye on the other data now and again.

Anyone with a 2007 model can confirm that the rocker switch was still there?

 

Mine is a 2007 A4. It has the button switch and trip computer has all the fuctions that you don't have on the 08 model.
