This topic has managed my life for the last three weeks as I am also having issues with my clutch.
After watching the three videos I am going to post for you I am certain that it is the ONLY way to properly diagnose and bleed your clutch system.
Pay special attention to the first video. In the first 5 minutes it will show you how to diagnose a clutch issue. This is key.
In the second video as well as the first it will show your how to properly bench bleed your system.
In the third video it will demonstrate how to disingage the hydraulic system.
