GT4 clutch troubles

[ralphmusic]

There was one with a clutch problem reported in the USA but does not seem to be the same behaviour as you report.

No other issues reported as far as I can see so back to the dealer.

Cheers, interesting problem on the one in the US. I presume my clutch is sticking upon release, but it does feel normal apart from the top of the travel, it will be interesting to hear others views, I'll call the garage tomorrow.

Over on PH a Spyder owners car has a slipping clutch after a few hundred miles ,not sure if is the same assembly on both cars. Car is back a dealers seems the problem was a oil seal went and contaminated the clutch if that makes sense

Hi everyone,

I took delivery of my first Porsche a couple of weeks back, a GT4. I took it for its first "spirited" road drive this weekend and was blown away by the car. My only critism was that the drivers seat doesnt go as low as the passengers, even the gearing felt right for me. I did however attempt to pull away briskly from rest and found the clutch didn't come up and just slipped, and according to my mate in the car behind me, there was quite a big cloud of spoke. Now I didn't just drop the clutch, but pull away Hard. I also then found that there was now 2 inches of dead travel at the top of the pedal. I just thought, hey maybe I fluffed it and the pedal will recover. I pulled away a hundred miles or so later from some lights, this time taking extra care to be smooth, limiting clutch riding and still the car stunk of clutch to a car behind. surely a car of this calibre should have a strong clutch? Before I go complaining to my nearest centre, has anyone else experienced this with regard to slipping or dead inches of travel, or is the clutch just left from a cayman s or something?

cheers,

Harry

It could be that, perhaps explains the excessive smoke. surprisingly though it doesn't slip once fully engaged.

How the Hell did you manage to get a Gt4 without buying other Porsche's ...? You married the Dp's daughter ... Lol

Well, I went into the dealer on the day it was announced. And they couldn't give me any info on numbers or letter of intents, and the trade in on my current was diabolical So it was a no. I changed my mind and came back in 3 weeks and put a deposit. I knew my chances were slim but I didn't want the car for another year, luckily for me enough people pulled out in front of me and here we are!

Would not take a deposit from me 2 weeks after release and I've had 7 Porsches including 2 GT cars.

I tried 4 OPC's, my 2 locals and 2 where I have bought cars previously.

Still I'm happy with the Boxster I have at the minute so will probably wait for a Gen2 GT4 or a Gen 2 GT3 if they are manuals.

Looked in at my local OPC this morning. They have a used GT4 available. Yours for £100,000. !!

And there was I thinking this thread was about burning clutches......doesn't happen with PDK, btw...[]

Harry,

Congrats on securing a GT4.

Back on subject, the GT4 clutch has a peak torque limiter designed to protect the clutch from misuse, for example side-stepping the clutch, but this is incorporated in the clutch slave cylinder circuit, so I can't think that its failure will produce the symptoms you describe. The brake pedal also has a clutch boost spring which reduces pedal effort, but again I can't see a problem with that being the source of your problem so it sounds as though there's a problem with the clutch itself and/or its release bearing or mechanism.

Best to get your dealer to check it out ASAP I think.

Hope you get it sorted quickly

In what way and situation does that work, I understood 4000 revs and drop the clutch on these cars, possibly not so bluntly but there or there about.

Geoff lane can't be too complaicent, he's had some dreamy metal. I've seen vids of the gt4 on Autocar I think launching by side stepping, I launched more gently than that, I think the pedal was stuck down half way but I can't say for sure as I was paying attention to the road. The clutch feels fine and returns strongly apart from this dead top travel. I to think it's a problem with the clutch material itself or it's not engaging fully so is slipping under launch conditions.I won't have chance to take it in for a few weeks but I will let you all know what my local OPC have to say and what it ends up being....

Steve,

My understanding is that the torque limiter is just a check valve in the hydraulic circuit which restricts the flow back from the slave cylinder when the clutch pedal is released, limiting the clutch engagement speed, so I guess that your suggestion is probably about right.

Harry, on such a new car covered by warranty as it is new call the OPC and they will get it trailered to their workshops distance shouldn't even be considered just a matter of them being able to collect it when convenient to you. Porsche Assist should be able to sort out the transport. Better to get it fixed ASAP.
