I was entering the freeway at a metered on-ramp. During my wait, the vehicle warned of objects that were close even though none were close to the vehicle. I then entered the freeway and several seconds later automatic emergency braking activated at a low speed of about 20-30 miles per hour with no car in front of me for about 100 ft, and the car that was there was not braking or slowing down. There was no apparent reason for the system to activate other than the already known fault documented…

I have reported the problem to Audi dealer but they advised that Audi has instructed them to apply software updates and not replace any parts. While the issue continues to re-appear, the…
