Did they only replace the CSC or did they do the CMC as well?

They said they couldn't find any leaks (external or internal) when they inspected my Z.

I'm concerned that replacing the fluid only is just a temp. fix (as z man has noted)

I took my Z out after they did the fluid swap and drove her pretty hard but, the oil temp. never got above about 190f. When I initially had the problem, the oil temp was up around 220f.

If my CSC or CMC is gonna fail, I'd like it to happen while my CPO warranty is still active....I've got until 2017 and/or about 80k miles before it runs out.

for future owners, thsi seems to be the key to the problem...this happenned to me as well..when the temp gets to around 220, if your having any kind of CSC or CMC problem, your pedal will STF

Home | National Highway Traffic Safety Administration (NHTSA), file a complaint. There are so many post about this failure but so few people have filed a complaint. Unless people make it known that there is a problem, the problem will continue. IJS

Interesting that I am reading this. Yesterday, I had the exact same issue identified on a brand new 2014 Track. Clutch all the way to the floor with no pressure. Finally came back but the 1-2 upshift seems way off now and the clutch has significantly more play in it. Had it for one month and no clutch drops, etc. Just some "spirited" driving. Going to contact my dealer about the bulletin. Great thread forum!

Dude I had 1,200 miles on mine when it went out. I highly recommend bringing them a high quality synthetic fluid to replace the crap that came in your car. It's not a fix but it'll definitely perform better. I'm at 43.5k now on the replacement CSC with no issues.

I called my dealer, they said nothing is outstanding for my car... Wasn't there a TSB?

I know this isn't a "Panacea" for clutch failure but I keep my fluid clean. The moment I notice it getting dirty, out it goes (from reservoir) and in goes new. Pump a few times, check it again, and if still dirty more out then more in. Don't have to change fluid often, maybe once a month (DD) but I feel better keeping the clutch dust out of the system as much as possible. Of course, where it gets in (around the O-Ring on the CSC sleeve) is impossible to prevent.

A funny thing I've noticed is that the black stuff "floats" to the top of the reservoir when I put clean fluid in. It looks like smoke rising from the outlet of the reservoir when the clean fluid is transparent, it's really easy to see.

Just as an FYI, Z1 appears to now offer both a heavy duty replacement CSC as well as a kit that eliminates the CSC entirely

Now, what about the master cylinder?

Working on this as well

We like to test parts thoroughly before release.
