Sticky: (Official) 370Z Clutch Pressure (CSC) Failures

Definitely first signs of CSC failure. The dealer will either 1) Say its normal and send you on your way (because "some" of them are a-holes) and 2) They will drain the fluid and fill it up with "GTR fluid" which technically its just a Band-Aid to the problem.

That's exactly what I was thinking. I'm hoping the fact that the service advisor was my old boss at one point, that he'll go to bat for me and hook me up. I'll keep my fingers crossed. I also have an issue where there's an intermittent tapping that you can feel in the clutch pedal when sitting idle. You can feel sort of a "tap tap tap" in the pedal when you slightly depress it. I've complained about this before but I was told the clutch operation was normal and they sent me packing.

Actually that is the master failing. The CSC typically fails catastrophically. The master often fails (causing the soft pedal) and then pressure returns or the system can be bled to return pressure. When one of them fails completely, the pedal will go to the floor and pressure will not return.

However, the failing internal seals in the master can allow contaminants by the seals and into the sealed clutch system. These contaminants cause additional wear on the internal CSC parts which are are already prone to failure. When a master seal slips, fresh fluid is the best counter to the extra risk of failure due to the contaminants introduced. But as you can see from elhombre's post, even that doesn't necessarily help.
