The trough out bearing got srap and part out on the pressure plate,, hope the tranny shaft is not damadge ;-(.
The pedal goes on the floor because it leaks somewhere, first look unther the car between the tranny and the engine you should see brake ioil come from the slave cylinder (if its broken) on in the car, from the master cyl ,,, yerk...
So 2 diffrent problem- trought out bearing - slave cyl.
you lll see when the tranny l be out.

Yes, I have a '90 200 Quattro Avant. I am having the same problem, and
will be installing a clutch kit this afternoon. Mine started with a noisy
release bearing, aka through out bearing. Now when I step on the clutch I
get a loud screeching, whirring sound, and sometimes the clutch peddle stay
on the floor, and I have to pull it up with the toe of shoe.
I think the problem is a shot pressure plate and bad release bearing. The
disc still holds tight, just the pressure plate fingers and bearing, are
bad. Well I'll know for sure in a few hours.
