I'm assuming there's a smaller number of issues about JUST the brake/DSC light? My car is an e90 06 330i and my cruise control is not working as well.
Any info would be appreciated.
I had a similar issue years ago. Turned out to be a rear wheel bearing that caused the ABS speed sensor to fault which shut down the ABS/DSC system at high speeds. Too BMW a week to figure it out, they had to send data to NJ to get their engineers to figure it out. Since you have the same car it may be worth examination. They changed the bearing and the abs speed sensor and it has been fine since (over 140,000 miles ago)
