would like to thank shipkiller on his help posts and others who posted possible fixes. I picked up 2003 Z4 about year ago with 21,000 miles. Needed a few things fixed, third light, brake issue( set too long without use ). Had issue with constant setting of DSC BRAKE fault, replaced brakes, rotors, sensors, still had recurring issues of random setting of fault light.
Help info was posted of trying to remove,clean and re-install the four sensors that check axle rotation ( one sensor on each wheel hub ). These were removed and found to have what looked like small dabs of rubber cement splattered on them, this was removed with electronic sensor spray cleaner, sensors re-installed, fault reset, NO recurring fault light! Issue seems to be fixed!
Thanks to all who blogged on this, I think I read every one!
