Hey everyone my DSC light is on and wont go off. Does anyone have any suggestions before i take it to the dealer and pay a ridiculous diagnosting fee.....Thanx
I feel for you. You really need the code but I dont think you will get anything form a generic OBD reader. I would check the yaw sensors on the suspension. I think it is Fr Lleft and Rt Rear. Its a little motor on the body with an arm attached to a bar that connects to the control arm. Contact with road debris could break it.
I don't believe those are yaw sensors. The yaw rate sensor is a gyro sensor mounted centrally in the car. Those are for automatically adjusting the headlight aim. Check your other post- you will need to have the car scanned.
You're right. I knew that once upon a time and forgot. I didnt see the other thread before I posted. Another possibility for the light is the DSC brake pressure sensor.
That is a good one. Other possibilities are ABS sensor, yaw rate sensor, steering angle sensor, or the big (and very common) ABS control unit. Unfortunately, the last is the most expensive, and also very common. It may tell you that one or more sensors are bad, or that there is a valve or something in the ABS that is bad, or it may just not communicate at all, but all of these usually mean the controller is bad. It is expensive, must come from BMW or you must have yours remaned (if possible, sometimes they are FUBAR) and must be programmed by BMW or by an independent with an Autologic or GT1. Look for around $800 in your couch cushions if that is the case. If it says one of the ABS sensors is bad, please have the sensor tested before letting them charge you to replace it only to find out you need an ABS controller. Does everyone see why I bug people not to double post?
Maybe we need more active moderators. They could combine the threads. Wouldn't an ABS sensor or ABS unit also throw a ABS light?
Good point. BMW3driver, what lights are on? If you can't describe it, post a picture. The dead ABS controller usually gives you the triple warning light of death syndrome (the triangle, the brake, and the ABS light.)
