Mine always goes off in one very specific location but nowhere else. It is a local junction where the road bends to the right and "left" is actually straight on, which I take. The weirdest thing is that it goes off every time but absolutely nowhere else, and I've driven all the way down to Gibraltar. No longer makes me jump though, so I'll live with it.
I had the exact same thing on the A4 I just handed back. Same place on route home where road goes right, and straight ahead is a side road lined with cars parked outside terraced houses. The A4 would ping at me just as I approached the bend, then the warning could cancel as I went right.
Worse still was a full emergency stop the A4 pulled on me as I passed a large coach parked in a layby. Again, the road was curving right, and I think the A4's AEB must have seen the coach, and kept on seeing it as I approached the layby and was gently curving right. The brakes came on, and I could do nothing to stop the car from stopping. The coach driver was stood infront of his coach in the layby and looked at me like I was some kind of idiot.
Thankfully, the lady behind me was far back and able to stop without crashing into me. Lord knows what she thought I was up to!
I took the car into Macclesfield Audi and they said there was a patch for the AEB's software, which they claimed they applied. It did not happen again, although it would still ping and even snatch at the brakes at odd times. There is a road in Congleton where the slope changes abruptly. In wet weather, the A4 would some times ping and briefly apply the brakes as I approached that change in slope, as if the AEB was seeing the road ahead and mistook it for a solid obstacle. However, as soon as the car reached the steeper part of the road, the alarm could cancel and the brakes release. This would likely only last half a second.
