Hello. As I mentioned at the beginning, I believe it hasn’t been tested and I would like someone to try it out to add it if it works. That said, and also in response to the other thread you mentioned
In gasoline cars, because combustion is much cleaner (they generate 5-10 times fewer particles) and the exhaust temperature is much higher (200-400º for diesel compared to about 500º in gasoline), it’s very, very rare that a regeneration is needed. For it to be necessary, you would have to always make very short trips where it doesn’t heat up properly and accumulates particles for a long time. Since as soon as the car hits the road/highway for a while, it cleans itself.
Now, if you can, feel free to try following the tutorial; the OBD is €7 and it’s always good to have it in case something happens. It’s very possible that some of the mentioned PIDs work and provide details about your GPF (gasoline particulate filter), although I don’t think they are all the same.
