Just broke down

[Popolou]

Sadly, driving home and just found I cannot select any gear. Held up a busy junction in North London but managed to pull to the side, ordered a pint and now waiting for the recovery vehicle

Basically: -

- With the engine running, I cannot select any gear including reverse.

- I can hear a light thump when attempting reverse which suggests the input shaft is ok.

- I’ve found engine off, I can select a gear and it allows me to pull away on startup (tried it slowly). Gear will then not come out with clutch fully depressed.

- The car is slowly creeping forward (under drive) despite the clutch fully pressed down.

Whilst waiting, anyone got any ideas? Clutch slave cylinder?

Cable come loose. If so, quick fix

[LiamH66]

Hydraulic clutch, so it won't be the cable.

Fingers gone soft on the diaphragm is a common one for this, but could be a master or slave cylinder leak stopping the clutch from fully releasing. If it's happened to me in other cars, I tend to put them in first before starting the engine, and then do my usual poor attempt at getting home without disengaging the clutch. Never had to attempt it in a Cayman yet.

Good luck!

[Popolou]

Cheers guys, managed to get the car back on the low loader. I'm also leaning towards it being either a slave cylinder failure or cracked pressure plate. Thinking about it more afterwards and i suspect i was doing the syncho's no justice hammering the thing into gear whilst the engine was running. Engine off, i could creep but there was no power to it. Found a few reports online suggesting others have had rotten luck with the same happening at 25k mls or 100kmls - am at 35k mls so it's a lottery.

Could also be the fork or the bearing, just don't know until i get it looked at. If this turns out to just be a clutch or a related part, i'll probably consider some upgrades like a lighter clutch or single-mass/LWFW.

[LiamH66]

Look on the bright side, at least it's not a PDK issue!

[Popolou]

Very true...just have doubts i will find a slot with a good indy this side of summer which could keep it off the road for a while. Car's been brilliant otherwise.

You didn't tell us the model and year. I'm sure not everyone here is dull enough to want to commit it to failing memory, but for some weird reason, that detail is of interest.

This.

I did not reply because of the lack of information.

[Popolou]

Sure, it's the MY06 987s as per my profile.

I meant the shifter cable

When I had symptoms that sound similar to the OPs (having recently been serviced at some expense by an OPC), I took my 2006 987.1 S manual to Precision Porsche who fixed it for £50. I've gone back there for servicing since then

[duncancallum]

Update?

Now with the indy so should be on the ramp today/tomorrow. Will post back with the findings.

My initial thoughts as well - running the short-shifter so began to think the slop in the cables needed adjusting with the tool. Noticed something wasn't quite right 6mo ago with the shifts not being as smooth and first/second not engaging as easily (even after a spirited drive) but chalked this up to a different gearbox oil that was used at service. Seems it was the start of whatever this is now.

[Popolou]

Pressure plate failure. Seems to be metal fatigue perhaps by the fork movement on the fingers?

[LiamH66]

Relatively common failure mode, and was my first guess. If centre plates didn't wear out, it would probably be the way most clutches reached the end of their life. I have brought it on myself back in impoverished days by changing a worn out centre plate and trying to get a second go from the cover.

When did this common workshop stuff get so bloody expensive. Looking at over 3k at £140 labour. Not sure which is more irritating, this or the additional 2hrs labour for the convenience of swapping out the RMS.

That seems very expensive, Revolution Porsche charge circa £750-800 for a clutch with an RMS costing £100 (while theyre in there)

Geniune parts from porsche?
Depends on location but id expect £140 is probably normal in some areas in 2025.
2 hours for a RMS replacement though? Jeez

[Popolou]

All genuine, from a well known Indy but it’s stuff like the RMS which just doesn’t sound right, casting doubt over my discussions with them.

[Tommie38]

Sounds like they are taking advantage of a punter that can’t drive away without getting work done.

If you do pay it, consider putting up an itemised invoice. Naming the company entirely up to you, but it wouldn’t be naming and shaming if it were factual.

I had a minor service on my 987S earlier this year. Porsche Indy, not main dealer. £529. Basically an oil and filters change. I know it takes a lot of oil, but I wasn't expecting that. Especially when the same service on my Q5 at Audi (it's in Warranty) cost me £249....

However, the 987 has also been eating brake discs - warped after <1500 miles a few times. I've had a lot of work done by said Indy to investigate, and a lot of work has been done effectively FoC, because the problem didn't go away. This makes the baseline service cost more palatable.
