Cayman 718 GPF Failure

Hi, thank you for the replies.

I have asked both Porsche GB and Porsche Centre Nottingham to put their decision in writing, once I have received them I will decide on the next course of action.

Porsche GB said they were just an importer of the vehicles and my contract is with Stratstone so take it up with them. They all need to learn about customer service because in my experience their attitude is appalling.

Regards, Mark

 
An appalling (if not unexpected) response from an organisation that seems to have completely lost the plot in terms of customer care in the interests of ever increasing profits.

The Motoring Ombudsman costs nothing and I’d also be seeking the advice of an experienced lawyer as to the best route/ argumentation to pursue this legally. I’d imagine if nothing else the oxygen of publicity might force a change of heart

 
FYI ...

All you need to know about the GPF, the particulate filter for petrol cars - Krosfou

When should the GPF be replaced ? Good news ! The GPF has therefore been designed to last. Its operation, correlated with that of petrol engines, ensures that soot is removed permanently and effectively. This means that you don't have to worry about clogging or any particular failure. So you don't have to worry about replacing this equipment, which has been developed to last the lifetime of your vehicle.

Perhaps something that is covered under warranty has caused the GPF to fail ?

 
Thank you for your input David. I had a phone call from the dealership yesterday basically saying pay for the replacement GPF or collect your vehicle. Porsche GB have sent an e-mail basically explaining they were closing the case, but it didn't answer my question of could they explain to me why this component isn't covered under warranty on a vehicle of this age and mileage. As I have said in previous posts, this is my fourth Porsche and my last, I will get the vehicle back and sell it and never have another one, this experience has taught me one thing - Porsche is a prestige brand but the dealerships and customer service are a mile off!!

 
Mark,

I really get how you feel with Porsche dealers and support, I suppose it could be worse you could own a McLaren, a real mess when it comes to quality control and dealer support! I know what I would do in this situation and have already posted those options, but I wish you all the best in getting this resolved in the way you want it resolved.

 
Mark, if you are getting no satisfaction from Porsche, it might be worth taking it to a respected indie. Basically you need a proper diagnosis where they test the associated components, sensors etc. It may not be the GPF itself. The Porsche approach is, seemingly, to just replace everything rather than find a specific fault, as it is easier to guarantee a fix.

 
Thank you John.

I have just had an e-mail from the Centre Principal at Nottingham saying that they will contribute a third, Porsche GB a third and I will contribute a third but Porsche Centre Bolton (Stratstone) where I purchased the vehicle from will cover 50 % of my share, so now the cost to me will be £1,119.50. I still believe I shouldn't be paying anything but this revised offer is better than the original £5,800 + VAT. Why couldn't this have been done 8 weeks ago?

 
This reminds me of a warranty issue I had about a year ago with my Spyder when they found a leaking condenser rad. There is a thread on here. They said it was not covered under warranty and was caused by detritus as the rad had rotted. The car had from memory 10k miles and was 2.5 years old. I had bought it 2nd hand so had the 2 years warranty but part of the original warranty still applied. I needed the car as I was going on holiday and despite a similar protracted debate with my argument being that the rads were covered by grills therefore I could not clean the rubbish out therefore not fit for purpose. My resolution was exactly the same as yours where I ended up paying 50% of a third of the total cost. This left a bad taste which still rankles when I read issues like this.

Porsche need to realise that producing good drivers cars does not entitle them to treat customers with contempt. The Porsche reliability record is not particularly good and brand loyalty can quickly disappear with this type of stance which is getting more common with the company. The economy is in a mess, finance is expensive and a lot of Porsche cars are unnecessary toys they need to be careful.

Really sorry it has turned out this way, you should not be paying anything IMO and if your like me the feeling you have at the moment will stay with you.

Sorry.

 
A small result for you Mark, but I agree that it’s something for which you shouldn’t have to pay. The problem is that if you don’t have it fixed the electronics will keep throwing up the CEL warning and will make it very difficult for you to sell the car, if that’s what you’re planning to do.

However, with respect to John’s comments, if the GPF is replaced and you still get the CEL warning - implying a sensor fault - you’d be within you rights to claim a full refund.[;)]

Hope there are no further delays in getting the car fixed so that you can get back to using the Cayman … at last!

Hi Geoff, thanks for the input, it really does leave a bitter taste. It leaves you with a feeling that they are not interested once they have your money, it's a take it or leave it attitude. They tell you the vehicle comes with a comprehensive two year warranty for peace of mind....try claiming on it and they put every obstacle in they way......they really make you feel special don't they!!!!

 
Agreed Mark. What I don’t understand is why Porsche seem to be very reluctant to throw this type of problem back to their suppliers when quite clearly there’s been a premature failure of a component. In addition to the common problem highlighted by Geoff, another example has been with crazing of the headlamp lenses reported on this forum in the past.

I appreciate that Porsche is a niche manufacturer, but if it had been someone like VW pressure would have been placed on the supplier to sort it out and - at the very least - replace the component FOC.

Regrettably Porsche's attitude and behaviour clearly follows the path outlined in the CEOs recent statement which was to screw the customer for as much as possible.

See also the way the OPCs favour certain customers and flip cars, both both pocketing large gains (tax free for the owner) to the detriment of other enthusiasts who would prefer to use a car rather than wrap it up in cotton wool

 
Interesting thread, I was chatting to a Cayman S owner last week, his 2019 car has had exactly the same failure and after much arguing the solution has been a third each between PGB, OPC and customer. Really terrible from a Porsche perspective and obviously going to be an issue for many who have GPFs going forward.

 
Hi, I definitely agree, this is going to be a problem, I think Porsche know this and that is why they are reluctant to cover it under the warranty.

 
The problem with all this emissions technology is that it frequently causes other issues.

If it were possible, I'd strip out the GPF and continue without it providing all the warning lights could be resolved.

 
It's a really bad situation, sorry to hear you can't get this resolved at no cost to yourself. Having just extended my warranty for anoyther three years I was expecting things like this to be covered.

I guess if it happens to my GT4 I'll go down the replacement Over Axle Pipe route and get the car re-mapped accordingly. I'd rather do that with my £1200!

Good luck..

 
Twinfan,

Something I may do with mine once the factory warranty expires, its well documented that the GPF's on our NA 4.0's cause the ECU to pull timing which in effect hurts power, a simple remove and deleting (masking) the EML can yield 30HP, stick a full bespoke tune on top of that and you can get the 4.0 to 450-460HP.

Another bonus is a better sounding car! win win!

either that or the Cargraphic Hi-Flow option
