R56 DSC and Traction Control
There's 3 different programs and you're confusing them.
DSC(includes ASC) this is the Stability control. You press the button once, and the Stability control goes off while ASC(anti-slip AKA traction control) remains activated. You have to press the button for 3 seconds to turn BOTH off.
So, if your car has DSC, you have Stability control AND Traction control, and you can turn off both or just the first one.
Note that ASC is a traditional traction control which cuts engine power to avoid losing traction, there are Mini's that don't have DSC(optional in One and Cooper models) but they do have ASC, which i think has been always standard in the whole Mini range of models.
DTC is the e-diff, which simulates an LSD using the brakes to improve traction. It doesn't cut power like traction control does.
This one is available if your car has the DTC option, and it's always ON.
Short version:
If your car has DSC, you can run:
DSC ON, ASC ON.
DSC OFF, ASC ON (press once)
DSC OFF, ASC OFF (press 3 seconds)
If your car has DTC, you can run:
DSC ON, ASC ON, DTC ON.
DSC OFF, ASC ON, DTC ON (press once)
DSC OFF, ASC OFF, DTC ON (press 3 seconds)
All Mini/BMW models work this way.

According to the manual, when the button is pressed for three seconds it turns off the DTC.
My understanding is that the later models don't make a distinction between DSC and ASC - the DSC replaced the ASC (w/ 2009 I think). DSC includes the functions of the ASC, but it is not another or distinct system in addition to the ASC. iirc, for the 2009 and later, DSC is standard (where ASC was standard prior to that).

"DTC is the e-diff, which simulates an LSD using the brakes to improve traction. It doesn't cut power like traction control does.

This is not worded correctly. EDLC (the e-diff) is part of DTC. DTC can be turned off but EDLC can not. It is not detrimental to autocrossing a base Cooper. If you have an S you can report back to us and let us know. Look for brake overheating.
As jcauseyfd notes, hold down the DTC button and both DSC and DTC will be turned off. You'll get a warning light in the speedo when this is so.

I'm glad I found this thread! I haven't properly gone through my owner's manual yet and having had my "justa" for a week now I was starting to get annoyed by the "hill assist" function. My driveway is on an incline and I'm pretty quick to engage the clutch when releasing the brake, so to my chagrin I found the clutch fighting the lingering brake drag from "hill assist." Since I've heard Cooper clutches tend to wear out sooner than average I don't want to aggravate things by trying to move forward with the brakes on once a day!
(mind you by sooner than average I'm comparing what I've heard to the 170k miles I got out of the original clutch on my 2001 GTi)
