I just wanted to share a recent experience I had with my Audi A4 B9 that scared the hell out of me with an unexpected and unwarranted pre-sense stop which manifested some of the worst neck and shoulder pain I've ever experienced that lasted for a week! I've only had the car about 4 weeks and since this happened, I've turned the pre-sense setting from medium to late and fingers crossed it hasn't done it again. However there is an element of distrust and paranoia about this causing my passengers or myself injury or worse an accident with whoever's behind when I least expect it. I was in a 30mph zone with no one in front of me and glorious weather, slightly up hill round a 45 degree bend that has a pub on the corner. As you approach this bend, your car is facing a pub and had people walking around in front of it. It was a little rural village location. Without warning, the car braked very aggressively for a split second, it didn't come to a full stop but was a significant enough stab of the brakes to kill all my momentum and catch me and the person behind me off guard and even leaving a few pedestrians looking at me wondering what the hell was going on due to the awful noise that came from the brakes and the car behind me giving me a blast of their horn. There was no prior warnings or bongs, just a violent stab of the brakes out of the blue and the only reason I knew it was pre-sense was due to the fact I caught a glimpse of the the dashboard saying pre-sense after the fact. I believe it reacted to people crossing the opening of the junction to the left. Thankfully it was only me in the car at the time as I ended up having whiplash for a week with some of the worst neck and shoulder pain I've ever experienced. Very worried about this causing an accident or injury to my passengers when I least expect it. Anyone else had any pre-sense stories?
