We have an Audi Q7 diesel that is part of the emissions scandal. Audi of Indianapolis has been unable to fix the car for any length of time. We will get the car back and usually have to take it back the same day because the check engine light is on yet again. This is not just for repairs every time we fill it up with AdBlue at the dealership the check engine light comes on which the dealer says is normal and to just keep driving it because the light will eventually go out. Just today found out that after they serviced it the previous owner traded it in for the same issues. The latest go around we had wait 2 weeks for a service. The battery went dead due to the defective glow plug and of course the dealer wanted to sell us a new battery when we had just replaced it due to the same issue. So, we had to have the car towed for this one. They gave us the car back last Friday and Saturday on the way to trade it in next door at the Volvo dealer the check engine light came back on. This time they said it needed reprogrammed. We use to get a service loaner, but not anymore so we have been without a vehicle for a month now. So, we had to walk Saturday to another dealership to borrow a car to get a ride home no offer of a loaner or so much as a ride from Audi of course. Got the car back yesterday and the put around they put 300 miles on the car and burned a full tank of our fuel returning the vehicle to us empty. This morning the check engine light is on again and we are going through Audi corporate. It has been a very dishonest experience. We have already started legal action through the Attorney General, and now are going to sue for damages.
