Audi Clutch Problems

[Alex Zhukovsky <azhukovs@fac.har.sunysb.edu>]

Hi  folks,
Thanks to those who replied. That clutch is not  hydravlic, I am just wondering,
can that be the pressure plate, which prevented from shifting to the
gear except when the engine is off and when the RPM's (resolutions
per minute) are just right for this gear. Or is it just the cable?
And can it be true that the clutch is slipping badly now, as 
mechanics say, although it never had a slightest intention of doing that.
Thanks,
Alex Zhukovsky.
