triple failure

today I got 3 yellow warning symbols(2001 740i sport pkg)abs ,dynamic brake,stability control.outside of fuses,wheel sensors what are any other common points.

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).

as of today ,the situation is as follows. I get intermitent failures, of not all but some of the systems-then no fails at all. then total fails. when the abs fail was not on I tested, annd the abs worked.I stil an think I need an abs mod. any comments

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

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.

I thank for your comments, had codes read all 3 came up,however since then ,I have all sorts of failure noticications plus no issues- various fails-no abs fails and some times no fails for 10 minutes of driving and then off and on fails. where are the wires refered to by claudios commentd thanks again

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?
