Gasoline Particulate Filter (GPF/OPF)
A gasoline particulate filter traps fine soot particles in the exhaust of petrol engines, mainly direct-injection ones.
What is Gasoline Particulate Filter (GPF/OPF)?
It works like a diesel particulate filter but runs hotter, so it regenerates more easily. It is common on European petrol cars since about 2018. A differential pressure sensor monitors it. Unlike diesel filters, GPFs often regenerate passively during normal driving because petrol exhaust is hotter. Ash still builds up slowly over the filter's life.
How it works
Exhaust passes through porous walls that trap particles, which burn off when hot.
Why it matters for your car
Very short trips can still load the filter. Warning lights call for a longer drive or service regeneration.
