I just purchased an Audi 2.0 A4 prem plus pkg. To the immediate right of the automatic gear shift there is a 3-inch long row of three slots. No one at the dealership could tell me what they were. There's nothing in the manual about it. My two guesses are that it's a: 1) change holder or 2) a charcoal filter intake for interior air quality. Do you know what it might be? Thanks
