Driving in traffic today, with no warning, the brakes were applied automatically with quite a bit of force and then released again. Luckily the car behind me didn't go into the back of me but could easily have caused an accident. There was no need to brake. This is a March 2016 Ocean, 150 dsg. It has acc but nothing was switched on. I'd say it was triggered by stationary car on my right I was passing which was on a slip road but I wasn't close to it as I was in my lane. Anyone else experienced this?
