Sorry, I turned it off with my SA but never drove the car with it off. He basically said it was for servicing so that it might help with pinpointing a problem.

Check out these two Yutube videos from the PDC skidpad. The first video is how the car behaves with DSC on:

The second video is how the car behaves with DSC off. You'll notice that in this video, the car can spin around completely, which is something that DSC would never allow:

It is definitely possible to fully disengage DSC/DTC by pushing and holding the dash button for at least 3 seconds. Both the the BMW Chassis Dynamics training manual and the Owner's manual fully explain this. They're attached below, but I can't get the attachments to work properly. The top image is from Chassis Dynamics manual for the E85, but it applies equally to the E9X. The bottom image is from the Owner's Manual
Was that a XI????

can someone please confirm with me that this = fully off stability and traction? and is it ok to drive with all these ridiculous errors and service warnings?
SO whatever became of this problem??
