My vehicle completely shut down while i was driving it 60 mph behind a semi truck and between two cement barriers. i have it on video, it is one of my problems i had with my car to say the least. it happened once more while i was not moving, had it in the audi dealer for the second time. after i brought it home, it wouldn't shut down. i also have that on video. the videos are too large to upload, but everyone that drives an audi should see these. i am glad i am alive to tell my story.
