Thread: Traction Control

Either a wheel alignment issue, steering angle sensor needs calibrating, or you've got a tyre with low pressure.

Edit - or your control arms need new bushes

I'm guessing you mean DSC rather than TC? My DSC has been doing that for a while and it's really annoying as it always kicks in on the best kinds of corners, when carrying a bit of speed. I'm getting a recurring fault regarding the Yaw Sensor, which I haven't as yet had replaced.

The steering angle sensor calibration as mentioned is an easy one to tick off - can do it yourself with a nanocom. As is making sure tyre pressures are ok.

Having lower control arms replaced definitely helped mine a lot but didn't get rid of it. The next thing on my list is front struts - the right one is definitely had it, and it's left handers, loading up the right front corner, that produce the DSC reaction.

It may end up being the yaw sensor but the other stuff all needed/needs attention anyway.

Good luck with yours, and report back if you manage to nail it!

I think any worn front end components that allow for excessive movement may set this off. For me it was the front struts. I replaced all 4 struts with low milage second hand units and it solved the issue. With mine the symptoms were almost identical and only on certain right hand corners. My ride was very 'floaty' due to the worn struts. My struts had done around 150k km.

Have you got miss matched tyres,ie new on rear old on front,that could confuse the ecu.
