Hi, I need your advice. Purchased a Q5 3.0 last night. Today at 257 miles (all highway) no stops - the emissions light went on. Audi said it could be 1 of 600 things and to bring it in for service. That the danger is if the light starts to blink, I must stop immediately and could jeopardize the automobile. Hello? I'm 3 states away. Now I'm at a hotel. Backing up the camera goes on and stays on for a good 1/4 of a mile while moving forward. My check has not even cleared. Have had the car less than 24 hours. What is your advice? I'm in disbelief. Thoughts? Thanks!!
