Exclamation DTC OFF = Burning tires!

Decided to give it a try......went to ---->settings---->>>DSC OFF and click DTC ON

Then waiting patiently in the red light for the green, pushed the gas pedal and for my surprise accelerating really fast and burning tires lol...

These are the settings:

1. Default position when you start the car:

The DSC+ system is active. The car has full stability and traction control. This means that the engine power will be cut if the driving wheels start to spin.

2. DTC on - Short press of the DTC button:

When you engage DTC, the DSC system remains active, but the limits at which it will intervene are increased. So the car will wheelspin a bit before engine power is reduced.

3. DSC+ off - Hold DTC button for more than 5 secs

This turns the traction and stability control systems off. The driver has full control and the engine power will not be reduced, no matter how much wheelspin you get or how far the car gets out of shape in a bend.

Officially, BMW state that DTC is for low traction situations, e.g. mud, gravel or ice. However, it's pretty clear that it's also designed to allow for a more sporting drive. Motoring journalists often describe it as emulating an electronic limited slip diff.

Let me tell you that you are wrong.....first of all there's 3 settings

1.- DSC ON - normal driving mode

2.- DTC ON - the DSC still active (there's your one tire spinning version)

3.- DTC OFF - Both tires spin, you are in your own. (careful with this option because all the engine torque is going thru the tires!!!)

Cool mate, no worries I will try is again next time I am due to replace my tyres, I didn't think our cars had a LSD fitted with all these other safety systems on board?

If the light is on it means that the system is OFF.
If the system is ON there should not be ANY light ON.

OFF=Singular burning tire. The car has an open diff, and will only spin 1 tire no matter how hard you try. I turn it off everytime I get in the car.

Yeah that is what I thought. I couldn't get both wheels to rotate at the same time on dry bitumen hence why I said save yourself the embarrassment in front of your friends

I think you either missed some options or you meant to say DSC off in #3. My car you can have DSC on or off and DTC on or off and any combination you choose.

Im still curious of actual function of dtc vs dsc. All I know is dsc on no spinning. dsc off spins tires. I haven't seen or felt any difference that I can tell with the dtc on or off. Maybe an actual explanation of functionality would clear things up.

DTC is for conditions like snow; it allows the tires to slip a little bit before cutting power. It's a relaxed version if traction control between "on" and "off."

that would make sense then, as my car seemed to handle very poorly with DSC on (normal mode) but today I had the dtc on and it handled much better in the snow as the car wasn't constantly trying to stop the tires from spinning at all.
