I have an Audi A4 2011 Sedan, I am driving this car since 2011 and all of a sudden my car had an issue without any prompts (when we try to start the car, it cranks and doesnt start). So I towed my car to AUDI showroom in Indianapolis and they told me that its not a battery issue, even LEAK test was performed and nothing was wrong in there. AUDI team told me that this issue is very unusual. Mileage is just around 70 k only and I got the last service done on 08/23/17 and I always got my service done at AUDI care. My AUDI care extended warranty expired in August 2017 and I didnt renew it. Not sure why and how the mechanical issue came up and the quoteto repair the car is too high (higher than the KBB value). I need advices and suggestions here. Also is there a way AUDI can help me on this.
