Drive a 2000 740i to relatives on Xmas eve - all working fine - left outdoors.
Start on 27th and the ABS, DSC and Brake lights all came on and the Sat Nav only updated every few minutes and became hopelessly confused. Actual braking unaffected, although one assumes the ABS was off.
I think it is a goosed ABS sensor and the faults are all related.
Any alternative views.
