Traction control

[wrmurphy81]

This is my first post and i am posting about my wifes 2006 330i. We bought it CPO a few months ago and it is awesome! I am hooked on BMW's now!

Does anyone know how to turn the traction control off? There is a big TCS button on the dash below the iDrive and i think I just press that button. I have tried it before but it doesnt seem to make much difference.

Is there something else i need to do or is that it.

Thanks!

That sounds to be it. Maybe double check the manual to confirm.

Welcome to Bimmerfest. Pressing the "DTC" button once engages Dynamic Traction Control. This mode allows more wheelspin and side slip before DSC intervenes. It's the best mode to be in if you need maximum acceleration from a stop but does not shut the system completely off. To do that you need to hold down the button for 3 seconds. This completely disables DTC/DSC functions. The next time you start the car it will default back to full-on.

On that note, under normal driving situations you should always leave DSC on. It does not intervene unless you are actually losing traction (wheelspin, understeer, oversteer, etc), and you will see a warning triangle appear in the IP. You will not notice a difference in everyday driving in any of the three modes unless you are driving the car near/beyond its limits of adhesion. Many believe that the system constantly interferes, which is not true.

correct.

the system is a fail safe which only engages when you lose control of the car.


now sometimes you want to lose control but probably not on the way to work in the rain.

That is great news. Thank you all for your help!

I think loss of traction and loss of control are two different things.

You never want to lose control of your car.

But there are times when you intentionally want to go into sliding traction vs rolling traction.

I've always found the older DSC intrusive when I purposely trail brake into a corner to get a bit of rotation of the back end. Throttle is shut down and abs activates to point me straight.:cry: I lose whatever momentum I intended to carry into the corner and there is a split second before I'm given my throttle back.

On the otherhand, I will always have DSC on when exploring a new back road especially if there is a chance of wet leaves in the road. The back end could step out very quickly and unpredictably. That's when DSC shines.
