have you busted a rthen the bleeder ear wheel brake cylinder
Could be that??? Clean Cardboard under each would catch that??

If the "Dealership" could not find the "issue??" I would thing it can't be that obvious?? In "Porsche World" the Clutch slave cylinders are "Notorious to bleed!!"

The "Bleeder valves" for the brakes are higher then the bleeder valve for the slave cylinder ... "air gets trapped." What we do is raise the rear of the car "higher than the front" to front to force the air to travel to the "high point!"

I'm thinking that most likely if this vehicle is on jack stands?? It's most likely level?? I'd think that maybe raising the rear "higher than the front and a combination of a 'Mighty Vac and pumping the brakes" would force any trapped air out of the system???

I'm thinking an air bubble "has to be trapped" in the "ABS Pump???"

I ended up figuring this out andci laughed so damn hard....i tore everything off that i replaced and checked for defects and inspected everything...the parts guy gave me calipers that were for performance braking. The piston was huge!! Changed them out and bleed it all again hard as a rock lol. Such a simple mistake i guess we gotta check parts before we install lol

Yes and just because you've gotten about "fuel pump" once and had it replaced under warranty ... apparently ... does not mean you won't get another bad one!!!

Porsche 951 spent weeks troubleshooting tore out the DME/KLR to check ohms and voltage ... all good and ignored the newly installed Fuel pressure gauge that refused to move off zero??? So yeah ... your not alone! :)

Any chance you took pictures, sounds like it could have happened to anyone ... how'd you find it???
