Cayman 718 GPF Failure

[Cyclemotor1958]

Hi Dan,

Without Prejudice

In the beginning I have always thought that as long as Porsche UK cover the cost of replacing these filters free of charge then we should have no need to go public.

Every case I have dealt with, they have eventually covered the cost, its not been easy, but with the GPF data information we have collected along the way its really helped.

We now know, and the dealers and Porsche know, that the original diagnosis on replacing these filters was incorrect, because the cars fitted with new filters are coming back with the same fault.

Currently we have several cars at the dealers that are having further investigations on the engines to look for possible oil contamination to support the high oil ash levels in the new filters. And from what I am hearing they are struggling to find a definitive fault, again positive news.

The only thing I would add to this is do not dismiss the AOS function on these cars, they need to be checked by the dealers more often.

To me its only a matter of time now after all this unnecessary work as been carried out, that Porsche will realise this is a software issue that needs immediate attention.

Its always been my intention to publish as much technical information has I could to help our owners and Porsche to get to a resolution quickly.

We now have the evidence to confirm that the incorrect oil used and the driving style excuses have no bearing on this problem.

And hopefully the dealers will stop embarrassing themselves by not even mentioning these excuses for the failures.

We need to protect the integrity of these vehicles, restore confidence in these cars, and fix these cars, because their is nothing out there that can equal the driving experience that these cars can give our owners.

I believe we are at a point now where after all the hard work that has been done, and the time spent, we could be closer to a resolution, we just need Porsche Technical to look at the software.

If you would like to be the person that contacts the motoring press then its up to you, I certainly will not be doing that.

Regards
David

Hi Glenn

Thanks for your post,

I sent off some information this morning to Jimmy, the chap in the video, to see if he would like to look at one of our cars.
Fingers crossed

Regards
Dave

For anyone who hasn’t received their printed copy here is a link to the digital version with the long awaited article on this GPF issue.. pages 74 to 76
Please share your thought’s..
We are still awaiting the stronger forum version and I believe a letter that was supposed to be sent from the club to Porsche HQ Reading..
Wouldn't it be great to get a formal quote/response back from these individuals that were due to receive their personal copy informing both the current and future owners what the conclusive root cause is and corrective action they are implementing to rectify

As a one-time engine designer (crikey, 50 years ago!) I think that is a very informative and well balanced article. It explains the challenges and the issues in an objective and unemotional way - hard to do when so much cost, obfuscation, work and emotion has been experienced by so many members and owners who have been involved. I sincerely hope that Porsche from both a technical and a marketing perspective give the Club and the owners appropriate recognition for the way that the article (and the work behind it) has been carried out and presented when it could easily have been much more public and confrontational. I think Porsche have been extremely slow to recognise and confront the issue. The comparison between the rapid and public response to eg 911 centre locks and the slow and painful 718 GPF gives the impression that Porsche think the 718 reputation isn't very important to them. Well done to all involved and I hope an appropriate and permanent technical and financial resolution is soon available for every owner.

Good article imho in the Post, and not just squeeeezed into a small gap, but 3 pages.
In the front of the Post is the usual column of the Porsche UK rep who seems new and keen. I think he is on the marketing side but also Customer Satisfaction.

Maybe a good route to the (UK) Top Brass?

There is still a lot going on behind the scenes (Thank you Dave!) Thanks to Richard Gotch for a well balanced piece which reads very well. It does not fully reflect the emotion and frustration that exists, for example on this forum, but it will hopefully open the door to a dialogue with the Porsche technical department and a discussion about the work Dave has been doing and the results. All along we have been tryng to find out what is actually going on with these GPF's and to avoid the situation where OPC's try to charge owners a great deal of money for what we believe is a mis-diagnosis. Someone must know.

Unfortunately the relationship between the club and Porsche GB is through the marketing department. We would like to talk to the techncal team. Fingers crossed that we will be able to do a follow up.
