Just a FWIW...
2003 X5 3.0 gave same indication after sitting in damp weather following a CV boot repair while we were out of town. Upon return, tried to take it 4hrs away & got this indication in addition to engine code about 50 miles in. After shut down & restart, good for 50 miles & repeat. Friend later told me it takes that long to run through all the codes on the bus.

Brake trifecta was a dirty sensor on the wheel that had the CV boot done. Mech had greasy hands when he put it back in. Very quick to clean & reinstall, so IMHO always worth doing when this indication surfaces. Wouldn't trust until I put 50 continuous miles on it though.
