Guess what I found on the floor?
My clutch pedal, again....usual scenario with zero Pentosin in the reservoir.
Topped it up and would not budge, manually pulled it up and pumped 12 or so times and it started to work but feels terrible, very on or off like.
So this will be the 3rd time, a charm I hope. Cant recall if they replaced the accumulator or slave last time but its starting to wear on me. She's being towed to the dealer as we speak.

I actually found fluid on the floor, directly under the engine. However previous times i did not, total mystery where it goes, I asked the dealer to no avail. It's almost comical then you realize your 140k car has a repetitive $250 crappy failing part problem and then it's not so funny. Highly disappointing, the turbo clutch feels like crap on a good day and should be similar to the gt2 setup to begin with.

I believe it shares a reservoir with the pwr steering, which probably has the capacity to take on a lot of extra volume. Mine was replaced under 'warranty', even though I was way out.

I guess this time its all run out the slave then....popped the seals or something. Like TT says the power steering reservoir soaked it up last time as it has the capacity. Mine went at 4,000kms and they did the slave first and it still overflowed the clutch master reservoir so then they did the accumulator and the slave together, making sure that the manufacture date of the parts was 2009 vintage. Apparently the earlier manufactured slaves had a problem somewhere. Just insist on seeing the boxes this time and make sure they use the late model parts....not earlier than 09. Hopefully that will do the trick 
...well thats what im hoping anyway. its a PITA when something like this happens once least of all twice and then leave you stranded. i still think the gt2 set up is a bit too stiff for a dd....maybe if the pedal was like a C2S that'd be fine. Each to his own though

funny you say that, I did notice a louder than normal 'noise' when I turned the wheel at a standstill loading it on to the flatbed. Sounded like a slightly higher pitched hydraulic noise, tough to explain.

When the accumulator fails, about a half quart of fluid can enter the unit, so that is why you don't see the loss of fluid.
Normally the diaphragm is like this: From what I can tell when you push the clutch pedal in, fluid pushes the diaphragm in on itself, and when you let of the clutch pedal, it springs back, pushing fluid back into the system.
When it fails due to a tear in the diaphragm, it collapses upon itself. If you look at a new one and put a nail or something like that in the hole in the top, the nail hits the top of the ball. If you put the nail in a bad unit, it falls into the unit to the bottom

so i went and checked my power steering reservoir and its kind of ver low, only the tip of the dipstick has oil, i have never seen any leak so is this going to happen to me soon, did any of you guys had to top of the power steering fluid ever, without the clutch problem?

Um, it is in the accumulator as the pictures show. I cut one open with a cutoff wheel to show the internals. There is no way to check it without removing the accumulator from the slave cylinder....just wait for the stiff pedal when you first start the car and you will know it is bad, lol. It takes a couple of specially bent and modified wrenches to get the accumulator out easily. If the accumulator goes, you can still drive the car just fine, it will have a stiff pedal when you first start the car, and after that it can feel slightly "notchy" but otherwise will function just fine.
