Thought I had this thing whooped--threw away my A4LD, replaced it with a FM146, new clutch, etc. Clutch would not release and I figured the master cylinder and a bad hydraulic line would fix it. Bled it just like the experts say and it checked okay. Gravity bled the slave and it initially felt okay, but when I cranked it up, same old stuff. No release. I'm going to yank the trans out and see what's up--not looking forward to more hours on the concrete
