DSC & Brake light both Yellow

[BCS_ZHP]

Describing this second hand, the wife is driving it. Both DSC light & brake light are illuminated yellow. Had her stop the car, pull & release the parking brake. With parking brake applied, the brake light is red (as it should be) and goes to yellow when she releases it. Had her try to reset the DSC button, no change. Had her turn the car off and restart it, both lights went off but as soon as she started to move the car they both returned.

So called the Indy for his Phone diagnosis. He said either the DSC controller under the hood has gone bad and that's an expensive little box or a wheel sensor has gone bad or been thrown and that's not too hateful. I'm going to have the wife drop it off at the Indy for a diagnosis.

Any other ideas?

I bet it's a faulty ABS sensor. Which are alot cheaper and more common to fail than the control module.

That combination of lights indicates the DSC is fully off, but I have no idea what the root cause might be.

Alignment or Wheel Speed Sensor.

+1 on the wheel speed sensor.

Alignment would have to be way off to trigger the light.

Droid X. Tapatalk. Use it.

Wheel speed sensor -- any rough estimates on what that might cost me?

[danewilson77]

Sensor....$150ish diy.

Shop.......over $200 with labor...depending on how much they like your pooper.

DW,
Thanks for that ROM estimate.

Wifey's pooper is cuter, will send her to the indy's shop. Maybe she can even carry in some baked goods, that tends to reduce the labor bill.

Had that happen to me once before, upon another start up it was gone. Googled cause and if I remember correctly, nothing is wrong unless consistently on as the others have pointed out.

had this happen on my m3 once in the past and i believe topping of the break fluid level solved the problem, but definitely a defective wheel sensor is a possibility. There are several threads about this on the m3forum.net if you search
