So about a week, and 300 miles ago my 328i Xserve got the trifecta. ABS, Traction control, and โ€œ4x4โ€ systems out.

Today I was going through a round about, and downshifted a bit to aggressively(read as poorly). Suddenly the DTC light flashed, than all the warning lights went off and now everything works again. Weird.
