Did the master cylinder go dry and suck in air?
Do you know how to activate the abs pump? Vag com method does not work on 2000 s4s... No option for this feature that year... Just says unavailable.Viridia said:You'll need either a push (Motive Pressure Bleeder) or a pull (MityVac) to get the air out, and you need to keep doing it until that air is out...even if it means buying Autozone brake fluid and wasting your SuperBlue. The dealerships bleeds with 2 bar of pressure on the system due to the anti-lock pump. Even after they feel "okay," you still need to drive it and activate the anti-lock pump to get those final bubbles out. I had a hell of a time bleeding my Porsche 6-pot calipers after letting the master cylinder run dry.
Yea I'm guessing it has to be the abs pump because when you pump the pedal and have your ear up to the pump, should like a squirting sound inside... Kind of like air and fluid... Ugh so frustratingViridia said:I was able to do mine without vag-cam. I ended up having to pump the Motive up to 20psi and then pump the brake pedal...I could feel it when it finally started coursing though.
