I have a 2020 Q3 prestige and was wondering what people’s experience have been with pre sense kicking in and alerting or braking for them? I have mine set to early and it does not seem to work. Was going around 30MPH and a car two lengths in front of me slammed on their brakes and I purposely did nothing for a 2 seconds and nothing tripped. This lead me to purposely trying to get it to trip and can’t. Been to the dealer twice and only a minor code was found. They also recalibrated the front camera. Why I don’t know since I am pretty sure it’s using the radar system. Also, adaptive cruise control works perfectly and you would think they use the same algorithms.
