I got the recovery back (ironically it was the same guy) but the powerpack didn't work this time, so we push started the car as I needed to drive to Leeds urgently (I live in London) and I had no issues driving up there.

Started fine for a 24 hour period, so I left it a further day and a half, and it still started (although I didn't drive the car, I just turned the engine over to check).
Leading evidence: 'same guy)' (1 discussions report identifying this cause; no attributable repair resolution).

Mine did the same and Porsche replaced the whole lot including the fobs.

Other checks revealed nothing (his check on the battery and alternator showed good), so he advised I give the car a good drive and to save my cash, which I did.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I got the recovery back (ironically it was the same guy) but the powerpack didn't work this time, so we push started the car as I needed to drive to Leeds urgently (I live in London) and I had no issues driving up there.
About 6 or 7 weeks ago, after being sat for a week, my Cayman S (57 - manual) wouldn't start. All electrics seemed to be funtioning but nothing on the ignition key (maybe a slight whirring noise, but no attempt at all to turn the engine over).
I got a mobile Porsche 'specialist' to come and look at it and he recommended a new battery. I purchased a new battery; same issue. He was giving me the run around, so I booked the car in with a local OPC and called my roadside assistance company expecting the car to be towed. The guy who came put a powerpack on the battery and it turned over first key. Other checks revealed nothing (his check on the battery and alternator showed good), so he advised I give the car a good drive and to save my cash, which I did. Car started for the rest of the day first key and was then left for 24 hours, at which point it wouldn't start again.
I got the recovery back (ironically it was the same guy) but the powerpack didn't work this time, so we push started the car as I needed to drive to Leeds urgently (I live in London) and I had no issues driving up there. I dropped the car straight with an OPC in Leeds as I have a friend who works there, but they couldn't find a fault despite having the car for over a week, with the car starting every time they tried it (they checked the clutch switch, ignition switch, earth straps, alternator, battery, starter, solenoid and all connections and relays etc - diagnostics computer shows no faults).
So I picked the car up and drove back to London. Started fine for a 24 hour period, so I left it a further day and a half, and it still started (although I didn't drive the car, I just turned the engine over to check). Left it a further 36 hours and it won't start again.
Battery reads 12.6 volts on the multimeter. I know that it's amps I need to start the car (and plenty of them) so could something be draining the battery of amps whilst leaving the voltage at 12.6? The voltage drops when I attempt to start the car and then slowly creeps back to 12.6. That said, I've tried my old battery after charging it manually and have also tried a battery from a 911 of a neighbour which we knew to be good as it starts his car, so I don't think it's battery related (at least no purely).
I really am at the end of my tether with this, and my pocket is already a lot lighter, so if anyone has any wisdom to offer, I would be grateful.
Similarly, if anyone could recommend a good independant Porsche specialist in the London area, I would be grateful. I'm thinking Jaz Porsche in Wembley, but I don't just want to keep chucking money at this without some further solid diagnostics.
Thanks all.
It was the VTS. Long story short, if I try to start the car without the VTS remote fob present it won't start. With the fob present it starts first key.
Prior to the 'fault', I could start the car with or without the VTS remote fob so something has changed. I'll get it checked out but for the moment, everything is cushty.
Glad it's finally sorted. VTS = Vehicle Tracking System (to save anyone else having to google it!)
I presume VTS is an optional extra that my '58 Cayman doesn't have?
It was explained to me that the VTS control unit is plugged into many other circuits within the car so when it goes tits up it does all sorts of weird and wonderful things !
The VTS system in your car can be configured for non-start without fob or just alert you/Cobra when the car is moved without a fob present. Ring Cobra and ask them to set it the way you want it (UK setting on early cas was alert - later systems immobilised as standard)
