Cayman 718 GPF Failure

Hi Glenn

Without Prejudice

We'll its been a while since I last posted, but we have been very busy with lots of GPF related issues, which are not all documented on this post.

Paul's car is still in the workshop, still not fixed as yet.

We also had a guy last week that had put down a deposit on a 2019 Cayman, he rang me reference our forum posts, we asked for the GPF report to check the data before he collected the car.

Unfortunately that was not forthcoming from the Dealer, so he cancelled purchasing car.

Last night I was contacted by another owner that was told by his Dealer he needed a new GPF filter, and it wasn't covered under warranty.

We are waiting for the GPF report to be sent to us.

We have another one of our cars going back to the Dealer to re check the oil ash reading %.

It had a new modified GPF filter 982 254 400AF fitted in Autumn last year, it was rechecked a few months ago and it was already showing 47%, same as Paul's.

Will up date you all, when the car goes in.

When is all this going to stop, 2 years battling with the Dealers and Porsche over this issue.

THESE FILTERS ARE NOT FULL OF ASH, AND THEY NEVER HAVE BEEN.

We have asked every dealer we have been involved with, to carry out a basic back pressure check using either a manometer or a pressure gauge, to confirm the ridiculously low differential pressure sensor readings we always see when the DTC code P242F (oil ash load exceeded) is present.

QUESS WHAT, THEY WILL NOT DO IT AND SHOW US THE READINGS.

And to make matters worse if we press the point about this extra test, we have been told to take the car somewhere else.

If we get any more dealers telling our owners that their GPF filters are blocked with ash, and it needs replacing, without a back pressure check being carried out, then we will post out the details of the Dealer involved and start a possible case against them for miss diagnosis.

I would like you to have a look at this video its reference our DTC code P242F, sorry its takes a bit of time.

It's all about a mileage limit set by the manufacturer on a DPF filter, which says the filter needs replacing after a certain milage covered.

But when the DPF is checked for a high differential pressure reading, it doesn't have high pressure, to confirm the filter is blocked.

SOUNDS FAMILIAR

The DPF is reset back, didn't need cleaning or replacing, or lots of diagnostic time spent, or even a regeneration, and certainly no road testing to try and clear the code.

WHY CAN'T OUR DEALERS DO THIS ON OUR CARS

We now have 54,000 views on this subject.
