Dynamic Stability Control

Hi all

i own a BMW X3 2006 Model with a 2.0d engine. In the past few days whilst turning a sharp corner on the left and accalarating the DSC warning light goes on and the front right tyre seems to be dragging. has any one ever came across this kind of problem

what do you mean by "dragging" ?

it seams as if the ABS is working on that wheel but with out pressing the foot breaks, the problem only comes when i accelarate

slip is detected, are all of your tires the same brand and worn evenly? its possible you steering wheel position sensor is out of whack so when you're turning it does not know and different rotating speeds cause the traction control to kick in? maybe even abs sensor on that wheel

hi, thanks for your reply.
all four tyers are almost new and i dont think its the ABS sensor caus last weak i swaped them.
I guess if it was the stearing position sensor the computer would diagnose it.

this is the DSC working.

When you turn left and accelerate, the wheel that generates the biggest turning forces is the front right tire and when it starts to slip the brake is applied to it. The only reason you feel this more than the rear DSC intervention is because the steering wheel is connected to it.


If you only lately started noticing this, its probably cause now the wear levels on the tires allow some slip.

Everything is OK dont worry.

If you want to experiment, keep the DTC button pressed till the 4x4 indicator lights up. Try the same turn again but be careful cause now there is no stability control to save you. Make sure you dont crash.
(I dont know how good of a driver you are, so I need to automatically assume that you are in-experienced so you dont shoot yourself in the foot)

hi
thanks to all. the problem was the tyers pressure. we inflated them all the same and it seams to be allright now. thanks again.
