How often do you guys get the clutch bled? I just had this done along with the brake fluid flush on my 07S. Just wondering how often the clutch itself should be bled. I think I only did it once over 17 yrs I had my Boxster, and the clutch seemed fine still.
Never done in any other cars I've done, which may not be wise to others but no issues in 15 cars and 500k plus miles. Brake fluid can last 3-4 years and no reason not to have them test moisture content to decide when to change. If you change yourself than cheap enough every 2 years is no big deal if you don't mind the time.
I got a bubble in mine. Was a PITA getting the clutch to disengage. Bleeding it fixed the problem. If you don't have a problem, I would not sweat it. I did it on a BMW once because it was on the service interval. Would have been easy with a helper. Really hard as just one.
The difference is, where the slave is located. On the 997.2 it is "not trivial" to reach it. I assume the same for the 2007. However, the trained tech's can do it without disassembling everything that I would have to to reach it.
Either flush (rather than bleed) it every time you flush the brakes, or do it never. Flushing the clutch regularly will get the crud out and help the seals survive longer, and it's what I do for my cars. Never flushing it will let sleeping dogs lie. Flushing it irregularly may dislodge crud that is benign where it rests (the sleeping dog), moving it to where it can compromise seals. Good luck!
I have been told the 997.2 clutch fluid is tied to the brake fluid. When you flush the brakes you are also flushing the clutch too.
I found some tech drawings I look at sometimes. This seems correct. There are goesintos as well as goesoutofs on this clutch system. So it must be flushing as you use it.
Both the 997.1 and 997. 2 have the hydraulic clutch system sharing fluid with the brake system, however, where the 997.2 self bleeds, the 997.1 requires a separate bleed process.
It should be done whenever the brake fluid is flushed as it's the same fluid.
I use a long bolt ratchet system with a silicone hose and catch bag. This let's you loosen the bleed screw and then retighten it without removing the tool and keeps things nice and tidy.
If most of the fluid is in reservoir and brake lines cw clutch, is it fair to assume when brake fluid is changed that any soluble contaminants in clutch fluid will equilabrate with much larger volume elsewhere over time. I assume flushing clutch separately will get out more nonsoluable "gunk," but that's probably pretty small amount. I didn't see in Porsche recommended service where clutch fluid flush should be done and my Indy didn't think important to do when I had brake fluid done last fall.

In a 997.2, yes, but I don't think so in a 997.1 as the fluid gets trapped in the clutch system and why it has a bleed nipple. With the right setup, it's a 5 minute job when you're changing oil and have access under the car. Use an assistant and do it the old fashion way. Them in the car and you under. Put the ratchet with hose on the bleed screw. Have them lightly push on the clutch pedal while you loosen the bleed screw - you only want them to push the pedal to about 80% of the travel. When they get to that level, have them hold it there while you tighten the bleed screw, then do this cycle a few times - maybe 3-5.
Thanks!... I don’t feel so bad for getting it done now. Lol. Clutch does feel nice and smooth and light, so can’t be that bad.

Clutch bleed intervals?
