The dashboard alarm lights (Brake, ABS, other) come on and I get an audible alarm while driving. This lasts for a few seconds and then back to normal ... until the next time. The battery and alternator were changed by the BMW dealer less than two years ago (not due to this problem which is recent). Any ideas on what could be the reason?
Could be multiple things causing a issue like this. From a wheel speed sensor, steering angle sensor, over voltage shutting the DSC down. Hard to say would need faults for further diagnosis.
