A Look into the DSC Brake Bleeding Routine

It's pretty commonly mentioned that there's a "DSC bleed" that's sometimes needed on these BMWs, but I didn't see any information out there actually showing the process. On the surface it sounds pretty simple, use a scanner device or ISTA to activate the DSC module and bleed fluid, but the routine is actually more complicated than that. I'll show you below what the routine looks like in ISTA.
