It might be HDC misbehaving... braking tiself at low speed sounds like HDC activated by its own...

It could be a sensor gone bad.
As you now have warning lights on there will be fault codes stored. It will be worth taking the car to get the codes read - that will tell you what is causing the problem.

In a case like this I would bring it in to the dealer. Needs to go somewhere that has the equipment to communicate with the DSC module and perform any tests related to this problem.

OK a friend has plugged a BMW Scanner 1.36 into it and read the ABS/DSC codes as:
Dec 6 Hex 0006 dec/hex 255/FF Does anyone know what these equate to in BMW "P" error codes? He also cleared the codes and as soon as the car moves the DSC light starts flashing and the brakes apply on random wheels. Thanks guys Paul

The code reader should have come with some kinda translation book, those codes mean nothing to me...
 I'd find a shop with the GT1 tester or bring it to the dealer as this may either end up being a DSC control module or a wiring issue. Either way would need proper diagnosis before spending money on unneeded parts.

Ok, the wheel speed sensor sounds like it fixed the braking problem. But what were the exact codes with the O2 sensors?
I ask because 9 times of 10 the faults are for lean mixture or rich mixture read by the O2 sensors, not a problem with the sensors itself....
