Hi all,

I have a 2019 718 Cayman T 2.0 (UK) which I have owned for just over 6 months now, I usually daily drive the car but with the coronavirus lockdown the car is only getting driven a couple of times a week. I have now noticed that when I first start and drive the car after a few days, I get no more than wastegate pressure (?) of a few psi from the turbo, as indicated from the digital display. The car also feels almost dangerously slow compared to what I'm used to, I timed it at around 8 seconds 0-60 instead of the usual 4 seconds or so. This doesn't seem to go away until I turn the car off and start it again at which point it behaves normally. When this first happened I put it down to a sensor having a bad day or whatever following a few days of sitting, but it has happened again today.
The car only has around 10k miles on it and it still under warranty of course so I will speak to Porsche about it next week, but I wondered if anyone has had similar issues or if there is anything I may be missing here?

Thanks,

All I can think is the electronic waste gate is opening early because the computer told it to. Naughty computer needs to be disciplined by the dealer. Everything in the control of the engine and turbo is electronic and from the ecu so there's no mechanical explanation* and nothing that can be done without a dealer level computer hookup.

*I'd say to check all the intake plumbing for a boost leak if the problem didn't correct itself after restarting the car.

Yep makes sense, lets hope the dealer doesn't try to fob me off.

Will do. Looks like all the dealers are closed here so I guess I'll just have to wait until their service departments are open again. Drove the car again today and it worked straight away, almost want it to get worse so that I can't get fobbed off, hopefully there is a fault logged in the car's computer somewhere.

Have you seen my thread? Is that related to your problem if the same thing failed?

I will have a listen when I shut down the car and report back.

Hi. Have had the same issue with my wife’s Boxter although didn’t turn the engine off so can’t say if that would have fixed it. Car is booked in with Porsche on the 4th June so will let you know.
Cheers

Sounds like a few of us with the base 2.0 are having some similar issues.

I posted these things that I've noticed on another thread yesterday -

Boost pressure is slipping at around 12psi, and falling to around 8psi (cycling from 12psi to 8psi maybe 3 times a second) with noticeable power fluctuations that feel like a juddering/pulsing.
Boost pressure sometimes never rises above around 5psi.
PSM light was coming on regularly, seemed to mainly come on following juddery power delivery under hard acceleration.
Yesterday I had a very loud noise when shifting from 1st to 2nd (PDK - but this definitely felt like an engine/turbo issue rather than gearbox) that resulted in the PSM warning and on the same journey the engine control management light came on momentarily following what felt like misfiring. I finished my journey ok but there was definite misfiring when idling - I'll be reluctant to drive anywhere until it's been looked at now.


The misfiring is still present at idle, although no warning lights. Using an OBDII reader i've got a record of codes showing misfires in cylinders 3 & 4.

The turbo issues seem to reset after a restart but there's definitely something very wrong - I'm booked in June 9th at OPC. Fingers crossed they can get to the bottom of all this...

Hopefully the misfire is just due to faulty coil packs. I've seen other people mention that some cars shipped with worse ones (I think it was earlier model years though).

I'm booked in but not until the 14th of July, apparently the earliest slot, perhaps a COVID backlog of issues. Will keep you all updated on mine.

Mine is giving very low boost when initially driving the car if its left to stand for a few days. I managed to video it - this is hard acceleration

Hi Gazza, did you manage to get a diagnosis/resolution? Mine is going in tomorrow, I’m thinking it could be useful if I can tell them how other similar issues have been diagnosed

I’ve heard back from Porsche, the issue I have is a seized up turbo wastegate actuator. Whole new turbocharger unit on order...

The technicians think all of the symptoms I’ve had are related to this, fingers crossed it’ll come back running flawlessly!
