GPF (Gasoline Particulate Filter) Issue

[olliesgrandad]

Well I was happily moving my 2022 eboxer into the car port from the driveway when suddenly an orange symbol appeared on the dashboard marked GPF with the information icon.

I waded through the owners manual and learnt the following. The car is fitted with a GPF and just like a diesel it may require regeneration if the car is driven in urban conditions a lot in low temperatures.

Personally I'd no idea that petrol cars had these or that the last generaton of the XV were fitted with these ,but subsequently learnt this is apparently a mandatory device under EU regulations since 2022.

Now here's the thing. To conduct the regeneration you have to drive the car in manual  gear mode without using cruise control at between 2000 and 2500 revs at a speed above 60kph for about 30 minutes  and periodically take your foot off the accelerator.

I live just off the M5 motorway so drove it on there . After 15 miles and about 20 minutes the warning light went out.

I understand if it won't clear it then becomes a dealer job to force  a regeneration.

I searched Youtube and could find very little information about the GPF.

I did however find a video of a guy with a 2024 Kia who had encountered the same issue. In his case he had to drive 80 kilometres to get his car to complete the regeneration so I feel very relieved mine only took 20 minutes.

Would I have bought my Subaru if I had realised this was going to be an iussue. Well I bought a hybrid to avoid diesels with a DPF and it would have been nice to know  I might have issues in the winter with short journeys.

By the way once the regeneration had finished I noticed that the performance of the car improved dramatically. 

I only use 'branded' petrol and every two or three tankfuls refuel with Shell V power.

Hope this information is of use.

That's interesting.  Another bit of 'corrective' engineering which causes more problems and will probably need further designed 'corrective engineering' to fix the previous corrective device.  Makes me think of the song, t;here was an old woman who swallowed  a fly...'!

Glad you got it sorted anyroad.
