Cayman 718 GPF Failure
- Thread starter Wrightrubber
- Start date
I’ve not seen that Dan! If true it would be a very late call given that at this advanced stage all the tooling will have been made and the production line prepared, but who knows with the current state of the EV market and with Porsche profits falling?
Hi Guys & Girls
Without Prejudice
Well another driver of a Cayman 718 2019 car contacted me again today.
Usual oil ash over load.
I know I've said this before but we have two issues that need sorting ASAP.
1. We need the engine management system on these cars to be able to re set the oil ash load to 0%.
If the engine light is on, and the code P242F is present, and the exhaust is not blocked, why can we not reset this value.
2. The soot warning light system needs to work on these cars, as detailed in the drivers manual. Surely a software update could be created to fix this issue.
If you type this into YouTube you will see how easy this could be.
VCDS-DPF (FAP)-reset value to 0%

Hi Dave,
Is that VAG software ? If so they already have the method within the group so no need to re-invent the wheel
Hi Paul,
Yes it's VAG software,
I have another car going in to a Porsche independent garage tomorrow to check the exhaust back pressure.
Will keep you all updated

Hi Sp1ke.

With regards to your question regarding 718 cars, all the replacement GPFs filters we have been involved in, have been 2019 cars.
Both the 2.0 and 2.5 engines, boxster or Cayman.
I have a friend with a Cayman GT4, he has never seen a soot warning light come on his dashboard.
And thankfully not had any oil ash warning lights displayed.
If you are thinking of purchasing one of these cars ask the dealer to confirm in writing that the car as a functioning soot warning light.
And in the event of the GPF requiring replacement it would be covered under warranty, either by Porsche or them.
Hopefully Porsche will sort out this issue and there will be no need for any of this.
Its becoming more clear that the GPF filters replaced on our cars over the last year, are now starting to show unacceptable high oil ash readings, over very low mileages covered.
We will be testing for exhaust back pressure on any future cars brought to our attention, to challenge the diagnosis that these GPF filters need replacing.
Porsche Technical need to look at the parameters set in the ECU, that control the emission system.
Where does the ECU get the oil ash measured value from, look at the algorithm.
Sorry to labour the point again, whey are the Dealers struggling to re set the oil ash % after the new filters have been replaced.
And why on our cars is the oil ash level increasing faster than it did before.
We will get to the bottom of this one way or the other.
Will keep intouch with any progress
