Hey you probably had questions about this but, I did a stage 2 + spec clutch and flywheel upgrade to my b6 a4, it was fine at first but now my clutch starts 2 grab before the actual release point, i was just wondering what it is, i went to the shop where i got my clutch done and they said it the master cylinder.
Does any1 knows how many hours the labor is?
And is it the clutch master cylinder?
Can you do it yourself?

 

Post in the A4 section if u havent resolved this yet

 

I won't pretend to know the answer to your question, but I had a clutch master cylinder put in my Honda over a year ago after it started to occasionally grind second. I had the shop do it since they already had the car after diagnosing the problem and it was relatively inexpensive as shop visits go (maybe about $200). At that price I would assume that the job isn't too involved if you wanted to do it yourself. I am sure you can find some directions online. Even if you find something for a Honda install, it can't be that drastically different from what you would have to do on your Audi.
