I don't know what to say. The Digital Handbook mentions it with a rider Depending on Drive Train option. Personally I would query it with the Dealership but they won't know why either. --- ### R — 2025-09-22T13:34:37+0200 (Sep 22, 2025) I thought most petrol engines these days had a particulate filter as well as a catalytic converter ?

DPF, is as far as I am aware for Diesel Engines only. Petrol does have a Catalytic converter and Diesel has both. --- ### — 2025-09-22T14:20:31+0200 (Sep 22, 2025) No Petrol have them too now, have one on my Golf R --- ### R — 2025-09-22T14:24:38+0200 (Sep 22, 2025) > [Lost Boy said:](/goto/post?id=761016) > > No Petrol have them too now, have one on my Golf R > > Click to expand... Yep, PPF for petrol, DPF for diesel --- ### — 2025-09-22T14:30:26+0200 (Sep 22, 2025) > [Lost Boy said:](/goto/post?id=761016) > > No Petrol have them too now, have one on my Golf R > > Click to expand... I'm afraid not. You have a GPF, similar but different to a DPF. Diesel Particulate Filter (DPF) captures soot from diesel engines, while a Gasoline Particulate Filter (GPF) captures finer particles from gasoline engines, particularly those with Gasoline Direct Injection (GDI). Both filters use a similar honeycomb structure to reduce harmful emissions, but GPFs are engineered with different porosity and thermal shock resistance to handle gasoline exhaust's unique particle types and temperatures, enabling them to meet stringent environmental regulations for both vehicle types. This video explains what GPFs are and how they work: [![](/proxy.php?image=https%3A%2F%2Fi.ytimg.com%2Fvi%2F14GmJlRaR34%2Fmqdefault.jpg%3Fsqp%3D-oaymwEGCPMCENEB%26rs%3DAMzJL3lDJ2k6UYmWjN90G6j6XzmTj4VaGQ&hash=48a7695fc4b2f3307ab31d0799419709) 48s Lubrizol360 YouTube · 9 Feb 2023](https://www.youtube.com/watch?v=14GmJlRaR34&t=10) [Diesel Particulate Filter (DPF)](https://www.google.com/search?client=ms-android-samsung-ss&sca_esv=3cba3ff7c6207a53&sxsrf=AE3TifNIxN-eh6NbaKrVSMbtpUX3JfQ0vQ%3A1758544027293&q=Diesel+Particulate+Filter+%28DPF%29&sa=X&ved=2ahUKEwjG7cWAr-yPAxWPYEEAHdNjFhMQxccNegUI1wEQAg&mstk=AUtExfCl3XOzsdhoejxbBidBL48aE3EXU1VHHZK4dDHLkDECRCHmuSYKvNILeyqzTMe3LFaaZ2e7iBNnQXjEVEqlbc7FdL9TTKE4rddXnE14dJUKGyr1P6kVcxSaUogBq3YLNZqURnfjhQ-qh0rK6Hz_7SsOO7BEyDRRlARj4xRShZ8ItbG86LeNOjgMNKEbb_BZIbtE9_kZfPnqFF0pR-NZb_Ef2oN2NI20tqXuLhZo-M-LRhvWWLKBBVD8cvYqL1eD1CtZApFQ-Ea-ekZXLZuHjwLa&csui=3) * + **Purpose:** Designed to trap and burn soot, which is a larger and denser particle found in diesel exhaust. + **Engine Type:** Used in diesel vehicles. + **Regeneration:** Requires a process called [passive or active regeneration](https://www.google.com/search?client=ms-android-samsung-ss&sca_esv=3cba3ff7c6207a53&sxsrf=AE3TifNIxN-eh6NbaKrVSMbtpUX3JfQ0vQ%3A1758544027293&q=passive+or+active+regeneration&sa=X&ved=2ahUKEwjG7cWAr-yPAxWPYEEAHdNjFhMQxccNegUI1gIQAQ&mstk=AUtExfCl3XOzsdhoejxbBidBL48aE3EXU1VHHZK4dDHLkDECRCHmuSYKvNILeyqzTMe3LFaaZ2e7iBNnQXjEVEqlbc7FdL9TTKE4rddXnE14dJUKGyr1P6kVcxSaUogBq3YLNZqURnfjhQ-qh0rK6Hz_7SsOO7BEyDRRlARj4xRShZ8ItbG86LeNOjgMNKEbb_BZIbtE9_kZfPnqFF0pR-NZb_Ef2oN2NI20tqXuLhZo-M-LRhvWWLKBBVD8cvYqL1eD1CtZApFQ-Ea-ekZXLZuHjwLa&csui=3) to burn off accumulated soot at high temperatures, which can sometimes struggle to occur in certain driving conditions.

Well if your comment in your Post 7 had been factually correct I wouldn’t have had to clarify. A GPF undertakes a passive regeneration rather than an active regeneration with a DPF. --- ### — 2025-09-22T15:53:42+0200 (Sep 22, 2025) Well full of gas that's for sure aren't you!

If you don’t know then say so or just say nothing. As you seem incapable of checking the accuracy of your information, and take umbrage when someone does and corrects your misinformation, hopefully others will check in future and not be misled. --- ### — 2025-09-22T20:02:33+0200 (Sep 22, 2025) I was correcting you who said that it didn’t have a particulate filter….

Only High Performance GDI petrol engines have a GPF in order to conform to the present Euro 6 emission standards. That is not the case in TSI engines produced by VW and used in the Hybrid. --- ### — 2025-09-22T21:53:28+0200 (Sep 22, 2025) > [WelshGas said:](/goto/post?id=761061) > > Incorrect.

Why would the dashboard state that there is a problem with the particulate filter, if there isn't any? And another wrong point: post #9 you state for DPF: **Purpose:** Designed to trap and burn soot Why do you have a DPF, if you just burn the soot? The reason for the DPF is to catch the soot. And when it is full of soot, you have to replace the DPF. The regeneration is for burning trapped, unburnt hydrocarbon. If the regeneration would just burn the soot, you don't need the DPF. Please study a little more before telling lies. --- ### P — 2025-09-22T22:20:40+0200 (Sep 22, 2025) I have asked the dealer and they have never seen or heard of that message before The vehicle has only done 1000 miles and 800 of those were at the weekend when I was deliberately using the Petrol engine on the straight bits to have more power on the twisty hilly bits The message happened nearly at the end of a 295 mile journey when there was zero EV power left Just not sure if this is a fault or something to expect regularly… are still not sure what I am supposed to do when the message appears? --- ### — 2025-09-22T23:03:09+0200 (Sep 22, 2025) > [TripleBee said:](/goto/post?id=761069) > > I am sorry to pop your balloon, but new petrol engines (even by VW) have particulate filters. > Why would the dashboard state that there is a problem with the particulate filter, if there isn't any? > And another wrong point: > post #9 you state for DPF: **Purpose:** Designed to trap and burn soot > Why do you have a DPF, if you just burn the soot?

Sorry to correct you. Not all petrol engines have a GPF, and their function is slightly different to a DPF and they passively regenerate. On a Diesel engine the DPF collects Soot particles, which are larger than the particles produced by petrol engines, which are then burnt at a high temperature during regeneration to produce a smaller volume of ASH which slowly builds up in volume over time until the DPF, now full of Ash, can no longer burn the soot and then fails and has to be replaced. Both Petrol and Diesel engines have a Catalytic Converter. A catalytic converter is a device in a vehicle's exhaust system that reduces harmful emissions. It works by converting toxic gases like carbon monoxide, hydrocarbons, and nitrogen oxides into less harmful substances like carbon dioxide, nitrogen, and water vapor. This conversion is achieved through a chemical reaction facilitated by a catalyst, typically a precious metal like platinum, palladium, or rhodium --- ### — 2025-09-23T09:13:06+0200 (Sep 23, 2025) [@TripleBee](https://vwcaliforniaclub.com/members/18951/), trust me its not worth the effort, this guy doesn't even have a California any longer and yet sits on here all day correcting others.
