Just press & hold the DSC button (not more than 10s) then everything (DSC+DTC) is switched off. If u just press the DSC button then only DSC is off as DTC remains on.
If u don't have DHP then the only thing u can do, if u want tighter handling, is to fit an aftermarket coilover system, but I'm not sure whether they're out yet for the xDrive. Adjustable systems such as KW offers acceptable ride quality together with improvement in handling.
