M2ki shorty_94 So i have another ABS module...What is "jumper" ?
update: So i measure as you said...wire between 87 and 30 pin, than one pin od the red spot , second pin on black spot and nothing, than i do the same but on old ground bolt or stud or whatever and than start pump buzzing, but i have flood of oil under the car ( so i guess that old place for ground is better but i am idiot and a few months back i break down that stud (orange arrow) so i find another place (yellow arrow) Is that big problem?
I cant get that ground wire back on place (orange arrow) (on picture is the other abs pump with good stud)
But i dont think that it could be that problem? Or yest? What about that oil came from steering oil can?Last edited by Tom_; 7 July 2018, 20:01.Audi Coupe Quattro 2.3 20V

It does not matter if connected to orange or yellow arrow. Both are connected to the pump chassis.
It seems you have corrosion on the pump chassis, it can be hard to get a reading than. You have to scratch on the surface for a good contacat.
If you have 12V between 87 and battery negative, but cant get a read between 87 and pump chassis i would suspect a bad ground. As the only time you get a reading the pump also starts buzzing.
As for the oil i think you have broken brake pipe.1989 Audi 80 Quattro

It comes from hydraulic reservoir cap, not brake fluid. So it doesnt make sense,why it overflow or what happened...So why it starts buzzing if i touch that red wire and old ground stud, with 87 and 30 pins bridged? And not the new ground? On the chassi is ground good...
How you mean "jumper" is that same for bridge by cable?Last edited by Tom_; 7 July 2018, 21:29.Audi Coupe Quattro 2.3 20V

This one is probably solved.
Problem was broken ground stud on the pump. New ground connection was made to the pump chassis, but the stud was broken in that way, it was no longer making a connection between the casing and brush assembly.1989 Audi 80 Quattro
