What software will activate the ABS pump on e53 3.0D model? I had a friend try carsoft and INPA with no success. (Albeit many others have had success with INPA). He can read and clear codes but no activation was allowed. I'm not sure if it is a software or HARDWARE problem

Reason for needing to bleed: Replaced my master cylinder. Then came a spongy pedal even after multiple power bleeding trials. I literally have no braking force.
