Abs light on, X1 dead

[YossarianPaso]

Hello folks!
Yesterday while driving I got the trifecta of lights in the screenshot (not my dash, I took it from the forum since it had the same lights), then it disappeared, came back a few seconds later, then the car in a few seconds slowly came to a stop and it did not start anymore.
Towed to the nearest mechanic, I am waiting tomorrow for news, but I wonder if you know what I should expect. I search through the forum and there are many posts on this, but most of them refers to an intermittent failure, not something that causes the car to suddenly die at the first occurrence
thank you!
