Clutch accumulator (?)
So have a ‘96 993 turbo, less than 35k miles. I shelled out $7k at the dealer to replace, among others, the clutch operating cylinder, pressure valve (which for some reason was more than a grand), and the clutch accumulator. Super expensive, but the clutch accumulator broke. That sucks and dealer is super expensive, but there is no substitute, fine.
But, literally twenty miles after the replacement, I’m in an underground parking lot, and boom, clutch goes hard, steering wheel has no assistance, and I’m spilling oil all over the place. Had to push the car up two floors, get the car on a flatbed, take it back to the dealers. Four weeks later, they are taking the position that the clutch accumulator was defective, was replaced under warranty. Dealer was unhelpful and sort of full of it, acting like I should be thankful that they are doing the replacement for free.
Sort of having a hard time believing that a genuine, simple Porsche part, brand new, just blows up, feels like an installation issue, but am I crazy? Been driving Porsches for 20 years, but last week bought a G63 over a Cayenne, in part because I’m losing faith in the brand....

What has a 24+ year old 993 Turbo having to do with Porsche Reliability got to do vs a new G63 over a new Cayenne....??? Sounds like a installation issue to me. I would question your mechanics competence. This would have no bearing on my decision to go Mercedes over Porsche plus the fact both vehicles are complete polar opposites.

Loosing faith in the brand? All because of a dealer, who may or may not have experience working on a 24 year old car, put in a defective part or installed it wrong?
New parts are not always perfect & dealers are known to not always be the best at working on these older cars.
Not saying Porsche is perfect, but seems like an odd reason to lose faith in any brand.

Relieved to hear I am not the only one. I had the exact thing happen to my 3TT this past summer and its being sorted. There is a bad batch of clutch slave cylinders in the parts supply chain and not the accumulator. Accumulator is cheap where as the slave cylinder is not. My clutch slave cylinder lasted 700 miles before blowing everything else up.
Also your clutch is now soaked with power steering fluid and it will slip when you put boost on it 5th gear and higher. All that needs to be replaced. I am fighting with Porsche to get reimbursed for all as the job was done at an indy shop or the indy shop is going to eat this replacement cost.
Paging Mark.. this should be in the 3TT section.

Why is there no substitute for dealer repairs? I thought it was the opposite with these cars. I wouldn’t even let the local Porsche dealer replace my hood shocks.

maybe its just me, but I feel like Porsche dealers were more driver oriented a decade ago. Now it feels like going to the bmw dealer.

I dumped the power slave cylinder years ago - now using a MPL slave cylinder to reduce the load, changed a bit of plumbing and changed out the pedal cluster spring, and the weight is about the same as my friends GT3RS - great feel too. I love the simplicity and much cheaper to replace. This does not work with a heavier pressure plate, but mine is a stock one on a RS flywheel.
Porsche parts are warranted for a year (I think) so there should be no whining from the dealer.
I am just saying that is an option when the power assisted slave goes again, which it will eventually. :-(
Cheers,
Mike

For anyone interested, I purchased a new accumulator years ago for my 1997 993 Turbo as a spare part figuring that like most Porsche parts, it would cost me much more when it eventually went out...well, it didn't and now that I've sold the car, it's still sitting in the original factory box, brand new. I'm going to post it in the classifieds and on the Porsche 993 swap thread when I get a moment but figured I'd make the folks on this thread aware. Judging by the comments above, it seems the quality of these have diminished in recent years...this one was purchased in 2014 - not sure if that makes any difference.

Most of the replacement and posts for the slave probably happened 10-15 years ago. (That thing is a royal pain to replace, and needs some modified tools).
The hydraulic lines are something that can fail too (this post reminded me due to my recent fuel line thread). Hydraulic lines would be reasonable to look at too. I’ve had mine fail 2x, drops right onto the exhaust!, got fed up and deleted the hydraulics all together (993 slave/964rs manual rack - changed to mpl slave and 993 clutch pedal assist spring). But can keep the power steering and just cap off the hydraulics and use a manual 993 slave).
fun stuff

Good point on the hydraulic lines… I’m loathe to change it from what Porsche intended, so will have it kept stock….
In general, these issues are getting tiresome. I chalk it up to it comes with a 30yo high performance car, but i am questioning the reliability lately…
