Brake fluid flushing + bleeding

I just completed my brake fluid flush on 01 330Ci. I flushed all the old fluid out on all 4 caplipers and also the clutch. Used the motive power bleeder, which made the job a lot easier.

I was told that the fluid capacity is around 1 litter for BMW e46. But I still have good 1/3 of a container full out of 1 liter container....

Wondering what might be the cause of this? Do all e46's have the same capacity? I looked at Bently manual, and I think it even said 1 litter for capacity. Maybe ABS holds some fluid that I can't get to because I don't have the tool?

As long as you bleed the bubbles and old fluid out- and your fluid res. is up to the fill mark youll be fine- I often have a little left after the bleed.

So I ran into problems after finally swapping my booster cause of that annoying sounds I've been getting in the cabin when the pedal is depressed.

I have successfully installed the booster and had to remove the abs unit + the brake lines connected to it. I bled the brakes and went in to start te car discovering that my brake pedal goes straight to the floor. I still can drive the car but need to floor the pedal to stop. I believe that since I disconnected my brake lines from the abs unit it introduced a lot of air in the module that is a PITA to get out. Is there any way to bleed the air our? I have the Motove power bleeder and tried the 2 man method twice. Still no cure.

I have heard the dealer has a special machine to "tickle" the unit to remove the air. Or I can find some gravel to activate the dsc to get the air moving. Anyone experienced this and found a solution? How much would the dealer charge?

Thanks guys!

You can crack those same brake lines at the ABS pump to attempt to remove some of the air. I'm not sure you need pressure (from a pressure bleeder or the two-man method) for this to work, but it can't really hurt. I would try that, and if it doesn't work, seek out an indy with a GT1 who can actuate the valves to remove bubbles. And yes, braking hard enough to engage ABS (I recommend wet pavement right after it rains) could also help to dislodge the bubbles.
