Cayman 718 GPF Failure

Hi Tony,

It will be interesting to see how this plays out, we have seen alot higher ash values recorded when these cars come out of the Porsche workshops after these modified filters have been fitted.

What would be great is if Porsche could tell us how they modified these filters way back in 2019, from a technical perspective.

It will be interesting to compare your original ash readings from day one on your spreadsheet, to current ash accumulation going forward.

You have the advantage of having this GPF information on your car, from day one.

We have another owner who has this same info on his car which shows a 75% ash level was present on his first service, at around 11K.
Unfortunately Porsche will not cover its replacement 100% after over a year of trying.

The memo says that these modified filters were fitted on these cars after December 2019, so what should have happened is Porsche should have called back in all the cars up to the December 2019 and replaced the filters.

Bearing in mind this is an emission part.

Most of our faulty cars are in this time frame, some are beyond.

They then could have monitored this ash level going forward and seen very quickly that this modified GPF didn't fix this fault.

These 718 2.0 and 2.5 cars are brilliant cars, nothing out there can compare with the driving experience, and enjoyment these cars provide. It ridiculous that they have been let down by a simple reset function in the software that should have been there from the start.

Look forward to seeing your ash results.

Morning Tony

Following on from our discussions regarding your ash returning in your software, you posted out on the 24th July that your ash level was at 1.96% after covering only 16 miles at PDI.

The other owner I mentioned who's car was registered in January 2019 found out his ash level was at 74.12 % when his car went in for a wheel repair on the 17th June 2020, his mileage was 8067 miles.

If we compare your ash reading taken at 7369 miles of 23.14% it really shows how quickly this software ash accumulation can build up.

This explains why Porsche and their Dealers were having to deal with this issue in the first year these cars came out.

There must have been lots of these cars with this fault for them to bring out a modified GPF filter with a different part number.

Obviously these GPF filters were fitted under the 3 year manufactures warranty so it wouldn't have been a problem for their customers, just a small inconvenience.

The information on the memo supports all this was true at the time.

Just a thought

Dave
