Petrol Particulate Filter Failure

[RandallF]

One of our members is reporting the failure of the Petrol Particulate Filter (PPF) fitted to his car and that its replacement is not covered by his extended warranty.

He says:

"I have enjoyed several Panamera`s over some 15 years and owned, from new, a 2019 hybrid.

The vehicle has been serviced by the Cambridge main dealership, and with 110k miles on the clock, enjoys the Porsche extended warranty.

On a recent journey a fault appeared which on recovery back to the dealership some 2 weeks ago has been diagnosed as a Petrol Particulate Filter.

The dealership advised yesterday that this part (some £2,500 + fitting) is not covered by the warranty which I find amazing!!. I wondered if you were able to share any such experience."

Have you had a similar experience? If so, we would like to hear from you.

Hi Randall,

For reference you might want to have a look at this long-running post on the Cayman forum where GPF failures have occurred on a number of earlier 718 F4-T cars without any warning signals to run the regeneration procedure. Again, owners with the Porsche Extended Warranty have found that they’re not covered for a replacement which, since the GPF is combined with the cat converter, means an eye-watering cost around £6k!

Cayman 718 GPF Failure

Hi Everyone, I have a 2019 Cayman 718, I have owned it for 13 months and purchased it from a Porsche Dealership as a Porsche Approved Pre-Owned Vehicle with 2 year warranty. I had an engine control fault come up on the dash, I contacted my local OPC and they informed me a long as the message is...

Thanks Jeff,

The Cayman thread makes sorry reading.

What is happening is a not uncommon gripe amongst not just Porsche owners, but by other premium car owners as well with an extended warranty.

Without looking at the small print of their Agreement, its a little bit of a swerve when the use of the words 'filters excluded' include the PPF, when in truth most owners would naturally believe what was being referred to were the air and oil filters and not think of the PPF as being excluded as a serviceable filter. A bit more clarity in the Agreement would probably save a lot of angst.

From what I understand a vehicle's warranty will only cover a PPF for structural failure. A blocked PPF is not covered because the issue originates upstream of the PPF.

A PPF being 'a service item' will need to be replaced at the end of its life. The lifespan of a PPF can vary by vehicle manufacturer and how the vehicle is driven and maintained. PPFs are designed to last more than 100,000 miles, but many will last much longer if the vehicle is operated where the average journey length is over longer distances. All a bit of a lottery.

I personally don’t agree with the stance of the manufacturers, but it’s been this way across the industry for some time as far as I know.
