    Odds are your ABS/DSC module failed

    I just replaced the ABS/DSC module in my Mom's 2000 740iL. In every case I read where you get all three error lights, the module itself is bad. If you only get an ABS or a DSC error, then a bad sensor is possible. However, all three lights is your omen.

    You can remove and send the module to www.modulemaster.com for a rebuild. Many folks have had success with that. We just bought a brand new module and installed it. The only trick to doing a new module is that it does require coding. So, you would have to take the car to a dealer or specialist after the install (if you do not have access to coding equipment yourself).

    The ASC/DSC and ABS error are misunderstood. Most likely the problem are the wire and sensors on the wheels. The wire problems are not visible to the naked... check these wires ASAP

    Get the car's diagnostics read by a BMW computer

    Check for frayed wires like in Claudo's post. However, the most important progress you will make is having the car's diagnostics codes read by a BMW computer. Then you will know exactly what is wrong.

    "all three" what came up?

    When you get the codes read by a BMW diagnostics computer, it will tell you specifically about errors in the wheel speed sensors, ABS module, steering wheel angle sensor, etc. What errors did you get?
