In a BMW you have two levels, except the ///M cars where you can set the wheel slip percentage via the I-Drive.

///M3 E46 got i Drive?

On the E90, E60 and beyond, its actually DSC Plus, that's why you have DTC.

DTC has two useful applications, one like mentioned by AB (in snowy/icy roads). Imagine if you at a traffic light junction and trying to take off, with the wheels spinning, DSC will intervene and you may get stucked.

Technically, let's say if the rear wheels are spinning 16% faster than the front, the electronics would intervened and cut off/reduced engine power and it the car still oversteers, individual braking will be applied, either front left/right depending on the corner direction.

Now with DTC switch on, the electronics will only intervened if the difference in wheel spin exceeds 20%. In our Malaysian context it means, more spirited driving around corners!! :)

Another feature of BMW's traction control system is DSC can be completely switched off. In the event you screwed up, just jammed the brakes and DSC would be activated automatically.

Have tried all except "auto activation".. simply because I don't simply jam brake in all situations.. something to do with instinct.. :p
 
sometimes i hear this "rrrrr..." sound from the rear wheel during fast and tight corners. Is that DSC / DTC at work?
 
If DSC is activated you should see the blinking amber light on your dash while it's on which is typically just a few seconds.
 
Back to schwarz initial question,...if the situation were to be the opposite, ie. the front wheel were stuck in the mud with a front wheel drive car, the same situation will probably repeat itself. In other words, in that situation where the set of wheels (2 wheel drive vehicle regardless if its front wheel drive or rear wheel drive) powering the vehicle is stuck on an angle with mud, this situation can only be avoided with a 4WD vehicle, period. Just my thoughts.
 
umm.. coincidentally parked on the grassy area but rear wheel area is a bit slightly muddy la.. so meaning i should use the DTC? upon recalling back what happened that night, i realized my car engine a bit weak too. maybe its trying to cut power because the rear wheel was spinning like mad (skidding sideways).. and after i moved my car to the tar road, i stopped and thanked the kancil driver, then after the fella cabut, i saw white smokes come out from exhaust pipe.. after i start driving then no more dy...

when i reach home, and parked my car off-ed engine.. i can hear there's water dripping sound from bottom the car...(but the floor no water drops, its dry) means what ah ?

i'm driving lci 323i.
