    I tried the thread chaser. Thanks for the idea on that. It was a M12x1.0 . Unfortunately, they don't seem to have that size anywhere that I could find so I made my own with some brake fittings I bought and then cut length wise slits into them with a dremmel.

    It didn't stop the leak, though so I went ahead and bought a used ABS pump and module (they are combined on my car)

    Above is the newest auto scan and now I don't know how to code this ABS unit. I tried entering the login as 09577 and soft code as 04277 like before but it is giving me 01044 fault code that it is incorrectly coded.

    I also tried again to bleed the brakes with this new ABS module in (both with the pedal and vacuum pump while running the car) but no fluid is coming out at the right rear. I'm willing to buy the pressure bleeder if anyone feels that would really solve my problem of getting the air out of the system and that I don't first need to run the ABS pump.

    Thanks again for everyone's help and advice.

    Go to ABS

    0x03 ( ABS ) -07 ( code controller ) -Input 04277 save/done.

    Make sure your VCDS has in config screen..............tester #, WSC, and importer # saved.

    Then do all your ADP's calibrations.

    You perform every step described here, then first deactivate ignition.

    Thanks once again. Got it to accept the coding for the new ABS pump. Here is the latest auto-scan

    Now I'm back to where I started at the beginning of this discussion. When I go into 03-ABS Brakes and then 04-Basic Settings I am getting the "Error Not Available" except for group 3. Also, when I go into the 03-Output Tests I press on "start/next" and the system immediately tells me it is finished testing. I am unable to choose a specific test like I think you can with the full version of VCDS.

    Yay! its coded...........

    No............. VCDS LITE the licensed version, should work just fine.

    It seems that this controller just doesn't support that procedure you are attempting.
    It is recommended to use PSI bleeder, mighty vac pull at bleeders........ or pump hold and dump repeating,
    ( While engine running ) the good old fashioned way.

    It is recommended to do a gravity bleed at each bleeder first.

    Jack, you were right again.
    I tried a gravity bleed (to be honest I never knew what it was before). Opened all the bleeder screws and it worked. It was very exciting to see that fluid come out each caliper again. Then used the vacuum bleeder to get clean fluid throughout and tightened everything up.

    Still not finished, though, because now I have a hard peddle until starting the engine and running where the peddle becomes soft again and sinks to the floor. I'm pretty sure I got the air out through all the calipers and am thinking that I must have damaged the master cylinder prior and could have been the reason for not being able to bleed with the peddle. The next step will be to replace the MC unless anyone thinks it might be something else.

    Master cylinders do go bad eventually, it is plausible the seals could be failing, you would need to disassemble it to be sure, or replace it.

    Some people like to bench bleed the 'New replacement' master cylinder before they install it, I think that is a good idea too.
    - Internet search 'bench bleed master cylinder' and you will see what I mean.

    Hope that helps,

    The best way to verify a master is bled............. is to pump fluid in reverse through each zone until the tank refills.
    The use of a mighty vac is recommended.
    or

    Quick and dirty poor mans way.
    Fill reservoir and open one line at the master and gravity bleed after you pumped the pedal like 10 times.

    Do twice for each zone if unsure and don't forget to have a rag or container collecting the dripping fluid.

    Like Peter said............. masters do go........they must be verified!

    I agree with the possibility that the internal seals in the master itself could be faulty but make sure the brake pads, rotors and mechanical sliders/pad anchor surfaces are OK. For example, a vehicle with the pad lining worn down in all 4 corners can make the pedal low. Likewise, frozen sliders and rusted outboard pads can make the pedal feel low.
