Cayman 718 GPF Failure

Excellent info -thanks for sharing. It’s to be hoped that all OPCs are well aware of this….makes me want to check my first service record….thank you

That’s really bad news

the only thing I have heard of in relation to GPF failure is if the wrong specification oil is used. Cars without GPFs use Porsche A40 spec oil (Eg Mobil One Gold Top). GPF equipped cars use C40 spec oil (eg Mobil One Green top).

Apparently using the older A40 oil will destroy the GPF. IT’s not impossible that someone put the wrong oil in. An OPC did try to sell me some gold top Mobil One for my GPF equipped car. Have a look at service receipts and check that the correct spec oil was used in your car; if not you could well have a claim against whoever serviced the car.

 
…sorry if this takes this slightly off topic….but just checked my first service paperwork and it doesn’t detail anything about the oil used - should it? Should I expect the dealer to have this info and share it with me?

 
So…..I had a 2017 base before and when I bought the GTS swapped the pouch of top up oil into the frunk so I had some spare. I think that bottle was open (with some oil on the outside and was silver with a blue top???). I checked last night and in the frunk is unopened green lidded container of C40…..so guessing it was put in there at the service….

 
Yep, sounds like it, although the top-up oil type is no guarantee of what actually went into the car as I think the front of house Service Advisor sorts out the top up not the Technician from the workshop.

Paul,

Looking back at a few invoices for my 987.2 CS it doesn’t look as though the specific oil used is referenced, just Mobil 0W-40, but then my car is pre-GPF.

I believe that the Porsche technician servicing the car follows a car-specific computer-generated list, ticking the box when each task is completed, so perhaps the correct oil is specified at that stage? Maybe that’s something to ask your dealer? Whatever, the oil’s going to come from a central tank, and presumably there will be a number of different tanks at each dealership.

Although Dave’s comment re the 1L oil top-up may be correct, there’s always been a part-used windscreen washer bottle in my car after every service, presumably left there by the technician, so it’s probable that the tech also puts the top-up oil in the car and is therefore responsible for its spec.

Jeff

 
I think you're right about the computer list for servicing (and therefore oil spec) Jeff, but I don't think the Tech sorts out the top-up oil as I got given the wrong one at my last service - hence me being told the Service Advisor had made a mistake [;)]

 
Happy to stand corrected Dave. Looks like differing responsibilities there.

I keep forgetting to decline the top-up oil at the service and wish that they’d source the windscreen washer fluid from a bulk supply. I’ve accumulated quite a few lightly used bottles over the years since I very rarely need to top-up the very large washer tank which comes with headlamp washers.😀

Jeff

 
You might not be wrong Jeff, maybe in my case the Service Advisor was made the scapegoat rather than the tech as it looks better that way!

My invoices (from Porsche Leeds) have always specified the oil used eg. Mobil 1 ESP X3 0w - 40

If it just said Mobil 1 0W - 40 then that would be the older oil.

 
Back on the topic, it would be good to hear how it gets resolved. The warranty exemption list clearly refers to filters which are related to fluids and greases. To claim that this also excludes the Cat/GPF which is an exhaust system failure just does not stack up. Have they also checked the sensors and the MAF which are also known to trigger this fault, or have they just gone for the big job?

 
Hi Everyone,

Just a quick update, the OPC has had the vehicle for three weeks now, they informed me they were waiting for Porsche UK to come back with some sort of resolution. They called me last Thursday to inform me that Porsche UK, the OPC and I would all contribute a third each. This meant my contribution would be £2239.98, I refused their offer and explained why it shouldn't be costing me anything, if it is a wear part, which they keep insisting it is, then it has failed prematurely and could they please go back to Porsche UK to find a different resolution, I await their reply!!! Regards, Mark

 
That’s disappointing news Mark, but not wholly unexpected given Porsche’s entrenched attitude to warranty claims.

I admire your persistence and hope that you get a satisfactory resolution … eventually!🙄

Jeff

 
Hang on. £5800 split 3 ways is £1900 but even so it shouldn’t cost you a penny.

id seriously raise the issue in writing to PORSCHE UK and even look at raising a case with the ombudsman. It may be worth seeking advice from Citizens advice.

I’d be arguing:-

a) It’s a non serviceable part so there is nothing you could do to prevent failure

b) Failure at that age/mileage must mean it was not fit for purpose in the first place - either faulty design or manufacture. I have a feeling that there is now a six year minimum life for major components.

c) Any single part that fails and then requires over £5000 of parts/Labour to repair must poorly designed - if it’s prone to failure why isn’t the design modular so only the failed part can be changed

d) Asking you to contribute a third means that Porsche and the OPC will cover their costs so they are not really paying anything.

Not sure of the limits on Small Claims Court but I’d be mentioning this Motoring Ombudsman in any response.

 
Sorry to hear of this Mark. I had a complete engine replacement with all ancillaries at 1800 miles on my 718 Spyder and rather cheekily asked if I could have anything off the old engine...... Even the engine oil was retained to be sent off with the engine so no chance. However, should you unfortunately (and incorrectly in my view) end up having to pay for part of the replacement cost, will you be entitled to retain part or all of the item?

Regards

Bill

 
Hi everyone,

Just an update both Porsche GB and Porsche Centre Nottingham refuse to do anything else they have told me to pay to have the filter replaced or collect the vehicle. After them having the vehicle for 7 weeks we are no further on, they have been so unprofessional throughout this whole experience, this is my fourth Porsche and after this experience my last. For a prestige brand they have handled the whole situation extremely poorly, I never want to deal with Porsche again and as for the warranty....forget it! Not worth the paper it's written on.

This whole episode leaves a very bitter taste!

Regards, Mark

I would certainly be getting a friendly motoring engineer to assist you and take the Porsche Centre to the small claims court. You have nothing to lose.

 
Hi Mark,

That’s disappointing news, but not wholly unexpected given the stance to date of Porsche GB and your Nottingham dealership.

Perhaps you should talk to Citizens Advice to ask if a legal route is open to you, maybe [as David has suggested] via the Small Claims Court or the Motoring Ombudsman? I’m sure that you can ask to keep the offending component, which could be useful if you’re considering getting an independent engineering assessment to support any claim.

I can understand your annoyance and frustration, but if you’ve not done so already it would be worth writing to the Nottingham dealer principal to make these points crystal clear to them. I have to say that I can’t get over the impression that Porsche - through its dealers - is more focused on their stated higher profitability targets than on customer satisfaction.

Jeff
