Do a google search using the following phrase: "BMW bifecta trifecta Bluebee"
This should pull up most of the threads discussed about this issue that plagues the e38/e39/e46/e53 generation of BMWs. Bluebee compiled a lot of info on how to diagnose this issue to either eliminate or point the finger at the various locations/sensors/components that may be causing the one, two, or three lights that are related to brakes, ABS, and traction control.
Check the fluid level. The reservoir is under the drivers side cabin filter. If that's fine then it can be a number of things - ABS module, speed sensor, steering angle sensor. If you don't have a scanner then look on eBay for a C310. They can read BMW ABS codes
Yes which is what prompted me to change brakes they were worn so bad i had holes showing thru the rotors so just changed everything but the calipars and fliuids also i noticed that my driver side tires has no wear sensor at all i see it on my passenger side so i just went to ebay and ordered break sensors maybe that will solve the problem
