Does PHEV have particulate filter? Got a dash warning!!

[Peter Chequers]

I thought this applied to diesel engines and mainly happened when doing lots of slower/short journeys

I was nearly home after 295 mile drive from Cornwall when the flashing amber message appeared on the dash

Mine is the 1.5 L petrol with plug in Hybrid

It went away after a couple of miles

No it doesn't . What was the exact message and light shown?

 

[Peter Chequers]

Flashing amber alert in LH side circular display

Exact message was ...

Particulate Filter Regeneration Reguired

Please see owners manual

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.

I thought most petrol engines these days had a particulate filter as well as a catalytic converter ?
May be wrong, im a bit out of touch these days

DPF, is as far as I am aware for Diesel Engines only. Petrol does have a Catalytic converter and Diesel has both.

No Petrol have them too now, have one on my Golf R

Yep, PPF for petrol, DPF for diesel

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:

Diesel Particulate Filter (DPF)

• • 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 to burn off accumulated soot at high temperatures, which can sometimes struggle to occur in certain driving conditions.
    

Gasoline Particulate Filter (GPF)

• • Purpose:
    Catches fine particulate matter (like carbon and ash) from gasoline engines, especially GDI engines, which produce more fine particles than traditional gasoline engines.
    
  • Engine Type:
    Used in gasoline vehicles.
    
  • Construction:
    Has a similar honeycomb structure to a DPF but uses a different material (like ceramic cordierite) with higher porosity and greater resistance to thermal shock to handle gasoline exhaust.
    
  • Regeneration:
    Can regenerate more easily than a DPF, as it naturally occurs when the engine is hot enough and the driver stops accelerating.
    

Key Differences Summarized

• • Vehicle Type: DPF is for diesel, GPF is for gasoline.
    
  • Particles Filtered: DPF filters soot; GPF filters finer, organic particles and ash.
    
  • Material and Design: GPFs use a more porous ceramic material and are engineered for higher thermal resistance compared to DPFs.
    
  • Regulatory Drivers: Both meet emissions standards, but GPFs were specifically introduced to address the increasing fine particulate matter from GDI engines, especially in response to regulations like Euro 6.2.

I suppose what we are trying to establish is has the petrol hybrid got one in whatever form that is, that’s going to bring up said warning light. As you say in your previous post, probably a question for the dealer

Just to confirm the Hybrid Multivan does not have a DPF or a GPF.

Well googled, i think we were trying to help the guy who asked the question, but perhaps being correct is more important for you....

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.

Well full of gas that's for sure aren't you! Keyboard warrior on google....congratulations!!

If you are going to give information that someone might rely on then be accurate. 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.

I was correcting you who said that it didn’t have a particulate filter…. At least he now knows that he has a filter.

Incorrect. The Hybrid Multivan does not have a DPF or GPF 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.

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? 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.

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?

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
