Here is a link on another forum so far describing what has been done. Any help would be greatly appreciated.

Anyone work on these? Any other clues? Going to see if I can find a way to do a bleed again. GMW and VAST are out, any other shops?

i cant see that link. What is wrong?

[Lucky736]

Jarett, Fixed it. Sorry about that.

Possible person fell through.

La la la.

Still looking, if anyone knows anyone.

I'm just talking from my experience with my Audi CQ and my Subaru Outback but here is my $0.02.  I don't think it is your slave and here's why.  If the slave were bad your pedal would stay on the floor.  You can put the car in gear with the engine off but cannot take it out of gear with the engine on or with 'load'?  Are you sure your shift fork isn't bent or broken?  If the clutch itself were bad it would slip but it wouldn't hinder shifting.

I'm not familiar with the B5 S4 but can you visually see the slave cylinder?  Can you get someone to press the clutch down so you can watch the action?  If you see it pushing on the fork that is a good sign that everything is working properly.

When the slave went on the Miata the pedal did return, but it was lighter than normal pushing down.   I guess it depends on the car if the pedal returns or not when the slave is bad.   I have no idea for an A4.

I would certainly try bleeding it again.  It seems very suspect that this happened after a brake job.  The car is acting like the clutch is always engaged.  You can't get it into gear when it's running.  You put it into gear when it's not running, but can't get it out when you start it in gear. 

If you're going to do the clutch and take it to a shop at least have them bleed it on the lift and you may get lucky.

Todays work:

Been a while. This car has been the least of my concerns. Two people said they had time to fix it, then had other projects to finish that are running long. So here I am taking a stab at it again.

So today....... gravity bled the clutch. Opened the brake fluid reservoir, attached a catch can and a line to the slave...... by the way, if you are reaching and remove the coolant overflow this isn't as bad as I had remembered it being, little scraped up but not bad from the top, anyway......... so the car seemed to be worse, meaning it seemed to engage more when trying to start it in gear.

Found this online: http://www.youtube.com/watch?v=wdf--suwqw0

Tried it with a cheap plastic oil can. Seemed to engage less in gear again. Bled it normal again, seemed to be worse. Did this alternative method again, for longer. It behaved on the first two presses of the pedal like nothing was wrong at all. Clicked through each gear with the pedal depressed, let it out a bit, pressed it in, clicked through some, let it out then it wouldn't go into gear again except when off.

Does this really seem like the clutch is bad? I guess, with it behaving like this I am wondering if that is the case why would it change how it behaves with only bleeding hydraulics.

Seems to me that if the clutch is bad, it's bad.  End of story.  Nothing you do as far as bleeding would change that.

If however you somehow damaged the slave bleeder (on my car the bleeder was plastic- yes, plastic) maybe you bleed the air out, but it's somehow allowing some air to get in.  Somehow air is getting into the system!  Check the hose going from the brake fluid reservoir.  Make sure it doesn't have a small hole somewhere in it.

It's the strangest thing. no leaks anywhere that I can see. Ug. This is why this stuff is best left to professionals I guess.
