I was enjoying some "spirited" driving this morning. I passed a truck and was moving quite nicely, got about 1/2 mile ahead of the truck. Suddenly, out of nowhere, the brakes activated, a message on the dash saying the presense was activated, the ABS was firing, and as fast as it turned on, it turned off. There was absolutely nothing in front of me, it's a sunny, clear day.

Called the Audi stealer, and asked what was going on. The service advisor told me because he wasn't there, he doesn't have any idea. I asked if this is a common problem, his answer was I should turn off the presense. While I don't enjoy non-answers, I decided to play his game. I asked what happens if there was someone behind me, he said the presense scans for cars behind me, sounds like BS to me.

If anyone can lend some knowledge on what happened with my car, it's really appreciated.
