I am a little concerned. I took the car to the dealer to top off fluids and such. They noticed this leak from which I believe is the clutch fluid resevior. There are no codes being thrown and my clutch operates perfectly, buttery smooth and grabs in the same place every time, grips crisp too.
The dealer only guessed it could be an early sign the clutch slave cylinder might be on its way out; (could be causing the fluid to backup out of the cap).

Any ideas or likely causes for this? Thanks!

Yep your dealer is correct. Do a search for much information on the subject.

Dealer guessed right based on my info/experience. Best book the car in to get the slave cylinder replaced. That fluid is not nice to have around outside of the reservoir.

oh boy, a few hours of labor for this one? (I ran a search, still trying to find what I need)

Would my braking be affected at all? I'm noticing a little reverberation under moderate braking only.

I found the part # and price of $380 so far.

i just bought one. best price i could find nationally was 500 and best to switch out accumulator also. add 140 part. same time to r&r them both

Yup check valve in the slave cylinder went bad. I suggest you change the accumulator also, while they are replacing the slave.
TT have power assisted clutches. The power steering pump provides assist to the slave cylinder. When the check valve goes bad in the slave, the fluid is forced back into the master reservoir, hence the overflow condition. I bet if you check your power steering fluid it will below the marks.
Braking is not effected.

Go to Gaudin Porsche for the cheapest original replacement parts
They have the accumulator for $113, and the slave for $348.

Thank you very much. I had actually just found that on the Gaudin website also. Im just curious as to how many hours a shop should charge me . . . .


I guess it cant be a bad seal on the resevoir cap etc? Sounds like everyone agrees on the slave, I was hesitant bc strangely enough the clutch operation is perfect.

its definitely not the cap lol iirc its 3.5 hrs book time? and the re-bleed can be time consuming.

I purchased my accumulator and slave from Gaudin, and had an indy install it, they charged me $325 for the install. I guess somewhere between $325 and $400 install should be expected.
Mine was okay for a short period of time then started to change its engagement pedal postion. it would randomly change as it got worse.

I had the slave and accumulator changed while we were doing other stuff in the area, but remember the total quote being around $1000-1200 if the job was done alone. My Indy was always more cost effective than he dealer, although I don't have a clue what they would charge.

sbefar01

Yup my shop says they can probably do the job without taking out the starter, its just tricky to do so, hence 3 hrs. They said it would be about $350 for the job. Seems reasonable to me. The clutch still drives great, looks to be a slow leak over time, I topped off the fluid, but I'll have to schedule the repair pretty soon to avoid a larger failure.

In the meantime wipe up all that Pentosin very carefully. It can be quite corrosive to the plastics/rubber it comes into contact with. You need to remove that cover panel with a hex screwdriver and clean it up good.

What do you clean it up with?
Brake clean? Soap and water?

Macster

IIRC Pentosin is water soluble. Whether you can flush the area clean with just water without getting water where it should get I can't say. Probably but that's no guarantee.

Be sure all the water catch basins/drains are clear before you put any water on anything. See that picture at the top of the thread? Notice that leaf? I would be surprised if there was *not* any leaf litter/plant trash in that car's front body water basins/drains.

I had the same problem last month. Took the car to the shop and had the repair done. Tonight I decided to remove all of the black plastic panels to clean them. I found the spilt over fluid on the firewall (bulkhead?) and I noticed that the huge wiring harness directly below is soaking with Pentosin. What am I to do?
Is this stuff going to eat up my wires?
