Well it happened to me today,while working on the car radio the x5 battery went dead so we boost it ,then i turned on the car and that yellow triangle,brake and ABS light were on.After disconnecting battery for about 15mins then reconnecting still the same lights ,so i told the guys i'll have my ind. mechanic put the computer on it,but when i backed the x5 out the driveway then drove forward for about a minute i looked down at the dash and the lights were gone......i said great...parked the x turned it off then on still no light ,i guess it reset itself.
