so i started up my car this morning and the TC & Anti Lock lights were on and i could not get the TC light to turn off... are both of these lights due to a fault in the abs system? perhaps a bad sensor?

I would say bad ABS sensor.

ABS/ASC lights on, Speedo Not Working, MPG gauge not working, and not recording miles.

most likely the outside temperature by you is about 85degrees farenheight. on my 99 528i, if the outside temp was above 85 degrees, and if i went to start my car the abs/asc lights would stay illuminated. but if it was night time, below 85 degrees, the lights would remain off until it either got too hot outside, or if youve left ur car heatsoak. pulling codes will indicate that you have

1)CAN Fault
2)RL Speed Sensor Open (speedo)
3)or rarly RR Speed Sensor Open (cruise)


the above leads to a bad abs controller.

take a flat head and open up your hood, and go to your abs module. slide the clip to the right and remove the 6 torx screws. t10 or t15. take out the module. and then go inside, wrap it in some aluminum foil, and pack it real well.

then go here http://www.modulemaster.com/orderform.html

and then enter in $300 plus shipping.. and then ship it to

but if the abs/asc lights stay on all the time no matter what. its probably a loose wheel pulse generator. or shorted. or open


but if the abs/asc lights only come on after moving 3-5 mph. then the wheel pulse generator is bad, or the exciter ring is bad. there was a TSB on this matter. vehicals produced after 9/98 to i think 11/99 had bad wheel pulse generators due to the manufacturing process of the pulse generators, they would form small hairline cracks and would allow moisture to penatrate the plastic pulse generator.

i thought it was a bad abs sensor... i'll try that first.
