Cayman 718 GPF Failure

Hi Mark, and Greenman986s

Without prejudice

Thanks for your posts guys, good feedback is always appreciated.

When think Mark how far we have come since you first posted out about your GPF.

Page 1, May 29th 2023, its taken along time, but have achieved alot.

We have managed to overturn Porsches desision to charge our members for replacing an expensive GPF filter they didnt need.

Sadly we couldn't help everyone with this issue.

We have proved along the way, when looking at the GPF data on these vehicles the data makes no sense at all.

We have struggled in most cases to get this info, but its proved that we were right from the beginning, no back pressure, no blocked exhaust.

The sad thing is we were told that the wrong engine oil, or driving style caused this issue, and it seemed the Dealers believed this was the case, they should be embarrassed.

Just think of all those customers stood at a Porsche reception desk trying to comprehend the news given, that they needed 8K to fix a car that was running ok.

No performance issues, no fuel economy etc, and at that time, no help from Porsche.

We were also told that the Porsche Extended Warranty wouldn't cover the replacement of the GPF, even though it wasn't listed in the exclusion section of the Warranty, funny it is now.

But the worst thing is the Major Miss Diagnosis of this fault, which we can prove 100%, due to all these modified filters that have been replaced, and its still an issue.

We set out over 2 years ago on a quest to help our owners and Porsche and the Dealers with this issue, and todate we have had no response at all.

Shocking, unbelievable you might say, we expect better from Porsche, these are expensive vehicles afterall.

But one thing for sure, we are going to save the reputation of the 718 GPF fitted cars, with or without Porsches help.

We have other avenues to go down, more research to do, please keep checking our forum.

Regards
Dave
