TL/DR: It was the low fluid sensor on the brake fluid reservoir.

2012 countryman with 60000 miles, about every 30 minutes of driving I would get 4 lights, the center exclamation point plus abs, traction and brake. A Google search led to a bad wheel pickup sensor seeming to be the most likely culprit. My tires needed rotating so I removed and cleaned all 4 sensors, they were dirty but no change to fault. So I was going to hook up an old ScanGauge to see if I could get a code but while looking at the code list some where around code # 2375 there was a low fluid code.

Added about 1/4 inch of DOT 4 to bring the level up the bottom of the screen in the brake fluid reservoir, another job well done.

 

How was it low. Did you have a leak or bleed the brakes.

 

I'm going with evaporation and lack of preventative maintenance. I never thought to check the level, out of sight out of mind.

 

Yea, should not have been low unless cap left undone or a bad job on the brake bleed and did not fill it back up by the previous owner or MINI dealership

 

THANK YOU! Just found this after dealing with flashing ABS and ! lights for two weeks.
