Hi Dan,
You must have been reading my mind, I sent out an email yesterday to Stuttgart for the attention of their Technical Department detailing our frustrations, see below.
We are also looking into the possibility of taking action against Dealers who have, and are continuing to diagnose this fault wrongly.
We have further detailed information that confirms that these filters are not blocked with Ash when the P242F code presents on the dashboard.
This Porsche information is further evidence that the repair strategy to fit these filters is flawed.
If the adaptation reset using none Porsche diagnostic equipment on several vehicles is successful and it holds a zero, we will send this information to Porsche Reading for their comments.
Hopefully with all the information we have, Porsche will have no excuse for not sorting out this issue.
Its always been our aim to try and convince Porsche Reading Technical to push this problem on to the people that can make the desision to look at the software.
And more importantly we want our owners to stay in these cars, theres nothing in the market that can compete with the handling, performance, and overall driving experience these cars can give us, we shouldn't have to be going to these lengths to convince our Dealers that correct diagnosis of this fault is all we need and expect.
They have fitted all the hardware they could on Paul's car and it made no difference to the Ash%, coming back.
My Email to Stuttgart:
I have been working for the last 3 years in conjunction with the Porsche Club GB Forum regarding issues with GPF filters blocking up prematurely on 2019 Cayman and Boxster 718 vehicles, 2.0 and 2.5.
The dealers have been asking their customers to pay around 9K, for replacing a OPF filter thats shown to be 100% blocked with ash.
Over the last 3 years, we have managed to get the OPF information on these cars and found that none of the emission control information made any sense at all.
This enabled us to challenge Porsche through their dealers, and they have fitted 14 of these new modified parts at their cost.
I have dealt with other 40 people, but unfortunatly most of them sold their cars because of this fault.
I managed to get hold of an internal memo sent from Porsche to their Dealers, in March last year, which confirmed they had this issue in the first year of production in 2019. The memo confirmed that they brought out a modified OPF filter which would fix this issue.
These modified filters have been fitted to 13 vehicles, and the ash % has come back, which confirms that these filters are not the cause of this fault.
There is a EU Regulation no 2017/1151 which covers the emission control of motor vehicles with particulate filters fitted.
I believe that the fact that this emission control fault was present on the 2019 cars, in the first year of production, that this would come under a manufacturing defect issue, and the manufacturer would be responsible for this fault.
This situation doesn't seem right, bearing in mind its connected to the emisions on the vehicle. It's clear that this is an issue with the emission control system on these cars. The software is telling the engine management system that the GPF filter is full of ash when it isn't.
It puts the engine light on, which if the car was in for an MOT, it would certainly fail.
I am not suggesting in any way that this is affecting the tail pipe emissions because no soot has ever been seen on any of the cars we have dealt with. The OPF tailpipe colour is correct and was working correctly on all the cars we have dealt with, dealing with the soot.
Yet these OPF filters are being removed, WHY
have a data base on all the vehicle's involved and further information on our Porsche GB Club and other 718 forums.
If you go onto the Porsche GB Club forum, you don't need to be a member and Search, Cayman 718 GPF issues. You can view 47 pages of information concerning this problem.
At the moment we have 154,000 views on this subject the highest views ever seen in the Porsche GB Clubs history.
We desperately need your help, our owners are getting rid of these vehicles because of the cost of this repair, this is a clear case of miss diagnosis and we should not be in this position.
These cars are brilliant, there is nothing out there that can compete with the handling, performance and overall build quality on these cars.
These cars are going out of the Porsche network and ending up in the trade, which is absolutely ridiculous, could you please contact me, you can ring me anytime.
My phone number is 07769 590119
Kind regards
David Hitch
Fingers crossed
