Not sure we are having a similar issue, but my 2017 2SS A8 started acting up last Monday. Thought the problem was just the battery and was corrected on Wednesday.
Fast forward to Friday and the car is freaking out again. This time the car starts no problem and we will see what the dealers says.
Sucks to watch the car go away on a flat bed twice in a week. Got a bad taste in my mouth about this.
