probably unnecessary, but I pump the pedal 12 times(ABS hates pedal pumping and the pedal drops) then bleed normally.
Bled an ABS system on an M3 a couple of months ago as if it was a non ABS system.
If the brake hydraulic circuits are going to be really drained, I bleed the caliper that is nearest the MC. This easier on the MC piston and for just in case the column of air that needs to be shoved out of the furthermost caliper is not of eual or greater volume than the MC stroke.
