Mine doesn't do it anymore with the updated spring-centered clutch.
Hard to figure out if it's related to the type of clutch more than to the way (how long/short) people slip it between neutral and first gear ...

Mine used to judder unitl I had the clutch replaced at 116,000 miles.

It was an asolute pain in the rear getting stuck in traffic and I hated it.

However the new clutch doesn't do this (touchwood )

I have heard that the clutch plate can get dirty/greasey/oily and when it gets hot it can slip.

Engine mounts go soft and cause judder and general vibration

My clutch lasted over 120k util I got it replaced. The clutch is still under warranty with an OPC and I was going to take it in today because it too judders like hell in traffic. Took it for a blast yesterday and it is fine when not in traffic and I just know that if I took it to the OPC today they would say that there is noting wrong with it and charge me an inspection fee so I think I will leave it.

Thanks for yur help so far, however a few more relevant questions:

Alexb - new clutch at 116000 miles, how many miles have you done now?
Johnmaddox - I was thinking down these lines too - did you have the clutch juddering and the mounts were found to be the fault?
968csreading - did your clutch judder before having it changed? why did you have it changed? Also I would take it back as they will know about the problem - like Scruffy101 found out, people will change the clutch and charge you for it without explaining all the options. I have been told that the problem can also be something to do with the flywheel, and even if you have that replaced the problem still re-appears.
It sounds like a fault that Porsche know about but are not willing to admit too - in fact, on another site's forum it states that Porsche stopped doing warranty repairs because the fault couldn't be cured!!

Any more ideas? We'll have it cracked soon and then I'll spend my money having it sorted.

Engine mounts a known cause of clutch judder and general vibration in 944's but not had this myself. The mount next to the exhaust is the one that fails due to heat. Porsche came up with a stronger mount for 944 Turbo which cured this. I think it can be retro fitted provided you get the longer bolts.

Have your mounts checked and do some research via Google.

It did judder before I changed it but the bite point was at the very top of the travel. The OPC was doing a good deal so I just got it changed. The flywheels are a known issue too and I have no doubt that it needs ether a new clutch or a flywheel. Worn engine mounts make sense too, at the end of the day these cars are no spring chickens anymore.

Can you tell me if changing the clutch actually cured the problem? On my 1989 944 Lux the clutch just failed at about 102000, I never actually suffered any juddering. On my current 1991 S2 (I'm second owner and have had it 12 months / 14000 miles), the clutch has always juddered when the car is hot. It's the original clutch, 153000 miles, and it works fine, except when I'm in traffic jams and it heats up and judders. I do find that there's less judder when I pull away in 2nd gear. As soon as it has had a run and cooled down it works fine again - until the next traffic jam. My mechanic seems to think that this is a 944 trait and that changing the clutch won't cure the problem. And what's this about changing to a non-rubber clutch? Any ideas please? Thank you.
FWIW, my 120,000 mile S2 is exactly the same. Get it hot in traffic - clutch will judder (very nastily if you try to reverse it into a parking space!) A few minutes open driving and it cools down and all is smoother than a baby's bum again.

As you said, original clutch.

I've probably done about 500-700 miles since clutch has been changed.

I try to aviod the M25 and taking the wife shopping, tends to burn the clutch up on the ramps or that's my excuse, a good swift drive after the traffic helps, try not to get too stressed by it, although my heart skips still when it happens. I think it's referred to as the character of the car!

The 968 is with the OPC today so it will be interesting to see what they say. Spent about 25 mins in stop start traffic last night which was interesting.

Update

They have confirmed that the clutch needs doing again.

Despite the clutch being under warranty with them until 5/11 and having done just under 10K of very light use they are claiming it is wear and tear.

Amazing how the original lasted 110K!!!!! The only help they gave me was to drop the labour from £105 / hr to £79 / hr. Total cost £818 - 10% discount for PCGB membership.

It still has some life in it so I am in no rush so I will start ringing round for some prices.

It's all very well going to OPCs, but you pay OPC prices for what is basically the same job as somebody else could do for a lot less. My mechanic is a VW-Audi authorised back street garage. He charges £32 an hour, but will use the same parts (which he doesn't charge OPC prices for) and the end result is the same. For example, our Z3 needed a new cat. BMW wanted £800, Stewart did it for £500 - fitted. He also stamps the service book with a VW-Audi stamp.Maybe you should look around for your own mechanic down there. I've just had a complete respray by the OPC bodyshop, and it's going back on Friday to do the bits they missed and stick the bits of trim back on that have fallen off since I collected it. It was Stewart who pointed out the paint defects the day I picked it up.

The reason it got resprayed is a long story, and it took them 12 weeks to do. I'll tell another time. Now off you go and find your own back street garage - there's plenty of VW-Audi approved ones out there. They had to be good to get the authorisation.

Forgot to say. If it was me it would be back to OPC and say that if it's under warranty then they change it, so long as you know that you haven't thrashed it to death. Tip - when I was having problems I telephoned Porsche customer services 08457 911911. They don't like it if a dealer is not coming up to Porsche standards. Give them a call, good luck.

968CSReading - sounds very fishy. I'd be getting a bit warm with the DP if they can really claim you are getting thro' a clutch in 10K miles. Particularly when the last one lasted over 10 times as long.

I agree, but if it is the flywheel that is causing the wear on the clutch I will look silly and have to pay more labour changes.

Assuming that you are still based in Reading? It would be worth giving Northway (in Benham, half way beatwean Reading and Newbury on the A4) for a second opinion and considerably better labour rates, even with the OPC's discount.

I normally use them and they were amazed at what they said but it is them tha have said the flywheel may be causing the wear.

Anyway, I dont have the cash at the moment so it will have to wait

It seems that what has happened to 968csreading is what Stewart (the mechanic) said would happen to me. I was in France last week and left the car with him for a new clutch. I phoned from France and he said that he's had a look (inspection holes etc), done his research, and at this time he didn't want to change the clutch because he thought it would not permanently fix the problem. His understanding is that if you change the clutch, and the flywheel is weak (something to do with it's construction), then the juddering will re-appear after a few months use. Then of course you suffer all the expense of doing the job again to replace the flywheel. To replace the flywheel and clutch at the same time is not cheap, but cheaper than doing the job twice. His advice to me is to wait until the clutch actually fails and then both units can be removed, inspected, and replaced if necessary. Seems like sound advice to me. It will be interesting to see how Alexb gets on over the next few months. You would think that these people, especially OPCs and Hartech with their experience, would think it worthwhile to remove and inspect the flywheel as a matter of routine when they change a clutch. By the way, I have had no judder at all since getting the car back on Saturday afternoon, but then I've not had to queue anywhere yet. Sorry to write so much each time.

Hmmm, all very interesting.

Presumably, a clutch-and-flywheel job is the same price as a clutch job, with the extra cost of a new flywheel thrown in.

How much are flywheels?

Yes I think I will leave mine as long as I can. It is terrible in traffic though, just have to use it at weekends.

The cheapest clutch kit I have found was at Euro car parts. £289 ish + VAT. Clutch kit was over £400. Sorry, prices are at work. I think it would be cheaper to buy the parts and get them fitted unless your specialist has good discounts with the suppliers.
