X-3 ABS system
I have a 2013 X3
I can only tell you what it felt like and what the dealership attributed it to since I am not very familiar with how the ABS works. It felt as if my brakes locked up and then it felt like a pumping sensation that caused the car lurch forward. I was simply braking for a red light in dry conditions. Dealership said it sounded like I was describing how the ABS system would react to slick pavement to keep from skidding .
