Faulty Dash Light

[Venn.D]

Noticed a fault light pop up on the dash yesterday on this '18 Q5, the little yellow triangle with the exclamation mark came on, but the car drives fine and there are no weird noises or performance changes. I scanned it with obdeleven and saw something vague about the brake electronics, but I'm not sure how serious it is
Is this something minor or something to worry about and what could be the cause

That warning's tricky, it could be anything from a low brake fluid sensor to a failing ABS module
