more problems with abs,dsc.

[amacman]

Hi every one, I was returning home from vacation with my family in my 2001 x5 4.4i sport auto,48k,cruising smoothly on highway when abs, dsc yellow lights illuminated then dsc inactive showed on info display. A few seconds later car shifted down gear and trans failsafe prog showed on info display. I continued 4 miles to service area, switched off ignition then restarted car and all was functioning as normal so i continued on highway for 10 miles until all same faults occured again, so i stopped car, switched off ignition then restarted car but this time yellow lights remained illuminated. I decided to continue driving until trans fail safe prog happened again. I stopped at services,switch off ,restart,try to drive but brakes apply themselves. I am seriously pi**ed with car and keep moving until brakes release after 100 yards,so i drive on highway with family seriously worried, Two more times we get trans failsafe but do stop start to get home. Can anyone please help with this problem before we all vent our anger on bmw? It does appear that these machines are not fit to be on public highways so what the F*CK can be done to sort these ridiculous problems?
