Hi John,
Without prejudice
Following our discussion this evening, I would like share the answer to your question regarding the readings on your previous post.
First of all, we very rarely see any figures except 0.00% in the K221 measured value, and K211 calculated value, when the Oil Ash measured value is at 100%.
We always see a 0.00% reading in the K230 Oil Ash calculated value.
This is all wrong, my understanding is the measured value can go up and down, and the calculated value is the ECU calculation of an average value over a certain time period.
This is has been our opinion for the last 2 years, and it doesn't make any sense at all.
Clearly the software is suspect, and needs looking at A.S.A.P.
Enclose this info below sent out by Porsche in 2018, prior to the release of our new 2019 GPF fitted cars.
The first batch of new GPF cars were 911 and 718.
It's funny that we have had recently two 2019 991.2 with GPFs fitted, with the same 718 issues we are having.
And on the first car, that had a new GPF fitted under warranty, we managed to see the GPF data, and that did not make any sense at all, I have a copy.
Porsche is making a model range fit for the coming emission standards
01/06/2018
Porsche continues to sell new vehicles in Europe as usual. The Stuttgart-based sports car manufacturer explicitly refutes a report to the contrary by the online edition of the Frankfurter Allgemeine Zeitung.
It is true that, currently, it is only possible to order through a Porsche dealership, rather than online. The transition to vehicles being fitted with a gasoline particulate filter (GPF) has resulted in limited configuration options. There is also very high demand.
From September 1, 2018, the Worldwide Harmonized Light Vehicles Test Procedure (WLTP) measurement cycles apply to all new cars in Europe and a new emission standard is also coming into force. Porsche is therefore making its model range fit for the coming emission standards. The introduction of new emissions legislation makes it necessary to transition the model range to use a gasoline particulate filter (GPF) and obtain new type approvals no later than September 1, 2018. As a result, a temporary restriction to the model range is in force. Despite this, in terms of ordering new models – even during the transition period – both prospective and current customers can make use of Porsche Centres.
As part of the transition, there will be a phased introduction of the model derivatives. Starting in September, selected models from the 911 and 718 model lines will be available with a gasoline particulate filter. The 911 4 GTS with all-wheel drive and PDK will also be available in three body shapes from the outset – as a Coupé, Cabriolet and Targa. Alongside the 911 4 GTS derivatives, the new technology for gasoline particulate filters (GPF) will be implemented into the 718 basic and GTS models and then into other model lines.
Porsche is prioritising the transition of model ranges to ensure that the most attractive possible product range remains available to customers. For two-door sports cars – where in some cases the proportion of vehicles featuring automatic gearboxes is over 90 percent – these versions will be introduced to the market particularly quickly.
For all new model launches that fall within the transition phase, all of the initial model variations available with a petrol engine will be fitted with a gasoline particulate filter from the outset. The market introduction of individual derivatives will take place step-by-step, as with a new launch.
Consumption data taking individual vehicle equipment into account
There are a number of challenges which have contributed to the delay: In accordance with the new legislation, vehicle manufacturers will in future have to specify individual consumption data, taking into account the individual vehicle equipment. Calculating this consumption data requires a wide variety of measurements.
“The EU deadlines for WLTP certification, which were brought forward at short notice by a year, are putting us under immense pressure. Our preparations have already been in full swing for more than a year, and we are making good progress”, says CEO Oliver Blume. “Due to a considerable shortage in the availability of test benches, which is affecting all manufacturers, this is currently a huge challenge. We need to prioritize. Nevertheless, we are in favour of more realistic emissions determination.”
Sorry if you have seen this before, but you can draw your own conclusions to what may have happened.

Dave
