For the ones who thought about brake temperature: I was thinking the same until I stumbled across the question: does the car know brake temperatures? I would think no.
For me it is still unclear why that function fails after some time. And why you do not even have ABS afterwards.

In my 2004 manual it states that HDC only works in a certain range (approx. 3-15 mph). It automatically disengages when speed is over approx. 35 mph.
Also, it states that in case of HDC malfunction (HDC light can't be turned on, switch does not work) its because HDC is temporarily unavailable because brake temperature is too high.
So, the system must have a way to know.
However, it does not say you would receive those other lights if in this temporary mode. Maybe its normal to get those lights when its in this temporary mode?
EDIT: Looking at the manual again. I believe that these lights come on normally when the HDC is unavailable. The DSC seems to be related to the HDC and of course the ABS.
Manual says DSC light comes on if DSC and HDC or the xDrive all-wheel system has failed.
If the brakes are overheated would it make sense for the ABS to still be functioning? I don't know.
