How did you go about cycling the ABS with INPA?So MAJOR success on my side! Indeed turned out to be the hydraulic unit half of the ABS system! I was able to determine this conclusively after I got plugged in with INPA. While cycling all of the ABS valves, got to the left-rear outlet and. . . no clicking!!! Removed the electronic front part and hooked it up to my spare unit and ran through everything again and all valves clicked properly, so then I went ahead and opened the lines, swapped in the good hydraulic unit, re-bled everything, and now brakes work properly again! Posting here in the hope this helps someone, key point being it was easy to hear which valve was non-functioning when cycling all of them in INPA!

These are the options that I have. Does it look the same for you? If yes, which sequence do you follow to activate the valves - first intake RR, exhaust RR, then RL, etc... ?
Have you inspected the pump?
Mine do that, too. The X5 and the M5. I mean air bubbles form in the bleed line. I never really thought they were coming from the nipple, though, so maybe it's different.Yesterday and today I had my neighbor give a hand with my brakes. We used ISTA+, latest version, to do the DSC venting. Ran the program twice but did not see/feel any change.
I also tried cracking each hard line coming off the Master Cylinder one at a time while the Power Bleeder was hooked up and my helper had pressure on the MC. I Did not see or hear any air escape, only some fluid weep before re-tightening the fitting.
Today while doing another ISTA+ purge, my helper spotted something odd after he closed the bleed nipple on the caliper. There were a large number of air bubbles coming out of the nipple hole that after a while stopped. With the nipple closed, where could the bubbles be coming from. The bubbles were definitely coming out the hole. I tried to capture a pix, but could not time it right. Because of the curve of the tube from the nipple, there was a couple of inches of brake fluid hanging there. I pressed very hard on the brake pedal to see if the fluid would move or more air come out. Did nothing, just sat there.
I will see about purchasing new nipples, clean the seats, etc... But I don't see the problem. There are no fluid leaks anywhere in the system.
This seems like the Oak Island mystery... more questions than answers!
The super red wolf blood eclipse?!?Was this done during the lunar eclipse?
I guess I would replace that nipple and rebleed. Have you checked all the soft lines for cracks/leaks?
I think OP will be howling at the moon if he doesn't solve this soon lol.The super red wolf blood eclipse?!?
