Greetings,

I have an '06 Manual Transmission Cayenne with 63,000 miles. I took the vehicle to the dealer when the clutch pedal suddenly lost pressure while I was driving. After checking it out, the dealer reported that all the fluid somehow escaped the clutch assembly. A worn or otherwise damaged bearing is suspected. Parts and labor will be roughly $4,000.00 to replace the entire clutch kit. Does anyone have any insights from having had a similar experience? Based on my driving history with other manual transmissions, I expected to get to at least 100,000 miles with this vehicle before replacing the clutch.

Thanks in advance for your comments.

-El

Sorry, I do not see how a clutch bearing failure could cause loss of clutch hydraulic fluid.

Perhaps find another shop and get a second opinion.

Thinking positively, I may have misunderstood the service rep's intent to explain that the cause of the fluid loss is unknown and the cause for replacing the clutch kit is the damaged bearing (due to the loss of fluid). I will, however, follow up and pursue additional opinions per your suggestion if clarification isn't forthcoming.

The clutch slave cylinder is an external type so either it, the connecting pipes or the clutch master is leaking. My money is on the slave being at fault. This would not damage the clutch assembly.

Concur even the small amount of fluid from slave cylinder leak if it were to somehow find its way in to the throwout bearing would not harm it (the bearing is sealed). The clutch disk may slip until the fluid burns off.

      Hello all,
       
      I've got a 2008 997 C4 w/ 56k miles on it. It was cold this morning (30 degrees F) and I noticed clutch slip for the first time since I bought the car in higher gears under full throttle. The clutch pedal feels very mushy and lost alot of its spring on the return. I stopped by my local shop and he confirmed its the clutch.
       
      The car is my daily driver but I do autocross about once a month and intend to track in the future. I told myself I'd get the light weight flywheel when its time to replace the clutch, and so it seems that time has come. I'm not adverse to the extra noise of the LWFW, but I've heard that you shouldn't do this mod on a C4. I see sharkwerks has a C4 project car with the LWFW so I assume it worked out, but who knows.
       
      Aside from the flywheel obviously I need a clutch. I've been looking at the Sachs stage 2.5 performance clutch kit, and it seems like a good option. I've also heard that the BBI clutch slave cylinder is an upgrade that would be helpful for clutch performance and feel.
       
      Questions:
      -Anyone have any experience with a LWFW on a C4?
      -Anyone have any experience with the Sach's stage 2.5 kit on a C4?
      -Any other clutch kit recommendations?
      -Anyone have any experience with replacing the clutch slave cylinder?
       
      Note: I'm going to get my IMS bearing inspected but if its not leaking I think I'm going to pass, seeing how I have 56k miles on it with no issues. Perhaps its past the infant mortality stage?
       
      Thanks,
       
      Jim

      2006 C2S, All highway driving. From past experience with my cars, I know that I am gentle on my clutch/trani. 108,000 miles on original clutch. Pedal travel is still 2.5-3.0 inches from floor to start of engagement. I do not think that pedal effort has increased. Am I on borrowed time? 
      Thoughts?
      Thanks in advance.

      Can the standard 2001 Boxster Roadster 2.7 L Porsche clutch friction disk be installed backwards?  If so what feature faces the forward (towards motor) direction?

      Hi Guys,
       
      Aircraft engine Tech, currently replacing the clutch on my AutoX 1999 996 C2, first time tackling a clutch/ IMS job.
       
      While the clutch & Pressure plate are worn out, I inspected the flywheel, based on Porsche's TSB 911 8/02 1360, & found it to be a bit worn, but serviceable. Common knowledge suggest to replace the flywheel every second clutch change or every 100K miles.
       
      Considering the high price of the flywheel, is it Worth it to replace it right now or I can expect it to last until the next clutch change?

      Looking for your help? I just did a complete clutch replacement on my 2003 Boxster. After getting the engine and transmission in and completely bleeding the clutch hydraulics 3 time, my clutch pedal sticks after depressing especially at higher rpms. Did something else break in the process? Thank you for your responses.
