When I asked to complete a survey by Audi USA about my Q4 about a month ago, I specifically mentioned Q4 owners in your situation. I stressed the importance in resolving software issues and broken promises to fellow Q4 Owners by Audi. I was asked to complete a dealer survey about 2 weeks ago. I mentioned it there also. Audi, like most auto manufacturers, is concerned about what is posted online because it turns up in Google searches and can impact sales. Sooner or later Audi will be forced to do something about your situation and others in a similar predicament.
I bought 9 BMWs over a 20 year period. BMW would absolutely have resolved your problem within 2 months max to your satisfaction by either fix to the problem or offer you a refund of some sort. Then again BMW software engineers and management are light years better than Audi. BMW software quality control is light years better than Audi plus they place great value on customer satisfaction and customer retention. Last year Audi USA made the most profit in history. I assume that Audi corporate across all regions did the same. Audi is just too cheap and too shortsighted to fix software issues in a professional manner. Because of issues like yours and Audi software incompetence, I’ll never buy another Audi.
