PPF Filter

[Doug99]

Hi All
I have been avoiding diesel cars as I do not drive a lot of miles which would be problematic for the diesel engine's DPF particle filter which requires regular burning off.
I have now been advised that my new lease petrol vehicle a 2025, 1.5 MHEV 163 Tekna 5dr [7 Seat] Xtronic has a PPF (petrol particle filter) which also requires regular burn off. I only use the car for local school runs so am not a happy bunny.
This the first time I have come across a petrol car with this issue.
Have they been around a while?
Cheers
Doug

I have a PPF (also known as a GPF) on a 2022 car. I think you will struggle to find a reasonably modern car which doesn't have one. They don't suffer as much with clogging problems as the diesel version (DPF) but they can clog with lots of idling and short trips. As you have an MHEV it probably wont idle much, it is likely to shut the engine off when the car isn't moving. Also the deceleration in gear which charges the MHEV battery helps to warm up the PPF and clear the soot. If the PPF light comes on it is a good idea to go on a longer run which includes hard acceleration and deceleration in gear, as soon as practical, to clear it.

Thanks pcaouolte, that sounds very reassuring

For even more reassurance I have just discovered that my wife's 2019 car has a PPF and she mainly uses it for a local run to school twice a day (about 2.5 miles each way). The PPF has caused no trouble as we didn't even realise that it had one.

Yeah, as Pcaouolte says, GPFs (PPFs) have been "a thing" now, for about 5 years. As petrol engines tend to run hotter than diesels and don't produce as much by way of particulates, they rarely give any trouble.
