 We have had continual problems with the computer and Advanced Keys.  The electricly operated trunk closed on my wife and hurt her, the HVAC is hard to control and does what it wants, the settings are nested inside the unit and are unsafe to operate while driving, the visibility to the rear required removing the rear headrest, the outward side visibility is poor as the mirrors are not wide enough and the pillar and seat back obscure side vision. The dealer cannot fix the problems and Audi has not "escalated" our complaints to where the regional or national reps will get involved.  We are tremendously unhappy and Audi has not helped.
