Hi 911hillclimber,
Without Prejudice
We are still waiting for responses from Porsche Dealers regarding all the vehicles that have gone back for the oil ash % check after a new modified filter as been fitted, and unfortunately the oil ash % figures are already at an unexpectable level, will update you all when we get some news.
Have a look again at all the work that was carried out on Pauls car, page 32, July 23rd, detailed on this forum, it doesn't make good reading, but does confirm Porsches attempts to try and solve this issue.
Regarding the return of the GPF filters, you would definitely expect that the manufacture would not be happy if these units were sent back to them as faulty, especially Pauls recent GPFs.
I would like to ask Porsche Reading, what happens when a 718 is sold out of the Porsche network, and the DTC code P242F is present.
I have had quite a few phone calls from new owners, with these cars, where the light has come on shortly after purchase.
We need to introduce a standard GPF condition check to be carried out, showing oil ash levels, whenever these cars are sold. This would protect new owners of these cars, and the data from these checks could be sent to Porsche Reading for analysis.
With all our Porsche Dealer sold vehicles with his fault, the journey to get Porsche to admit liability hasn't been easy, but we got there eventually, but dealing with independent garages is not has straight forward.
In fact its been terrible, the usual reply from the selling dealer, is get your vehicle diagnosed, speak to your warranty company, and no the GPF is not covered.
Your on your own.
Also another disturbing trend, is that we are seeing many reports where these cars are being fitted with different exhausts and the GPF is programmed out, to remove this fault from the car. This is because the cost to replace a GPF filter, THATS not faulty, has been the only current option available from the Dealers, hopefully this should stop now.
Its illegal to remove a GPF, unless its for track use only, if you look at the tail pipes on a 718, you will not see any soot at all, check out a 981, and see the difference.
It seems very simple to me that after 2 years of dealing with Porsche Dealers and Porsche we have a situation that Dealer sold cars, have had worked carried out on these cars covered by the manufacturer.
In August 2024 we had conformation in writing from the Porsche Customer Relations Hub in Reading, that the GPF filter fault on one of our cars was identified by the Technical and Warranty Teams to a Manufacturing Defect.
Sadly the owner of this car has recently sold it due the the oil ash level coming back.
In March this year we had further conformation in writing by way of an internal memo to the Dealers explaining what to do if the DTC P242F, (oil ash load to high) presents itself.
This memo clearly explains what the Service departments need to do regarding the possible causes of engine oil getting in to the cylinders, and causing the formation of Ash particles.
On the 2 vehicles that have had the engines removed, stripped down to try and find signs of engine oil getting into places it shouldn't, nothing was found, confirming the engines were not the issue.
Various detailed checks had to be carried out, then if no oil was found to be present, a GPF regeneration had then to be carried out.
This was to see if the GPF ash load would reset, if it didn't re set, the GPF should be replaced and re tested.
Again no mention of a simple back pressure check to be carried out.
We have proven beyond any doubt on our cars, that have had new filters fitted, the filter is not the issue.
The memo went on to say, a new GPF (982254400AF) had been modified to prevent this issue. All vehicles with a production date later than December 2019 should already have the modified GPF fitted, and are not relevant to the document. If there are any issues outside of this model year range, please contact Porsche.
It seems to me with all this information we have above, that Porsche Dealers need to support our independent garages, and new owners, if a vehicle has this GPF issue, there should be a procedure to follow which should be implemented to at least record these faulty cars, and give reassurance to new purchasing owners, that they will not be cast adrift.
At that moment if you own a 718 4.0 GTS, or a GT4, you are in a very good place, we need to fix our cars and put them back in a good place.
There is nothing on the road that equals the driving experience of the 718 2.0 and 2.5 cars, we need these entry level cars, not every one likes 911s.
Any feedback would be appreciated, we are on 81K views at the moment, thankyou all for your interest, and support.
