Hi, first time posting I was driving on newly opened freeway tunnel, which is about 9kms long. 5mins after entering the tunnel the Audi pre sense activated on 3 consecutive occasions, and decelerated my car from 80km to about 70km. This happened within the space of 2 minutes with no traffic in front or behind me. Needless to say I was freaked out and very lucky that there no vehicles travelling behind me. Has anybody else experienced this. I’ve had my A7 for just over a week.
