GPF/OPF Off - Petrol Particulate Filter Deactivation
Software deactivation of the petrol particulate filter (GPF/OPF) to end clogging and regeneration issues.
The GPF (Gasoline Particulate Filter) and OPF (Otto Particulate Filter) are the petrol equivalent of the DPF, fitted from Euro 6d onwards to trap soot in a petrol exhaust.
Like the diesel filter they clog over time, which costs power, raises fuel consumption and brings the same kind of regeneration problems. On a petrol car those symptoms can be just as awkward to live with.
GPF/OPF Off deactivates the related ECU functions, including the particulate sensors, the regeneration cycles, the pressure monitoring and the fault codes. Applied together with physical removal of the filter, the engine then runs cleanly at full performance with no warnings.
It is the petrol counterpart to DPF Off and is used for the same reasons. Because it removes an emission-control device, GPF/OPF Off is intended for off-road, motorsport or export use and may not be legal for road use in many countries, so the owner is responsible for checking local regulations.

Frequently Asked Questions
What does GPF/OPF Off do?
It removes the petrol particulate filter logic from the ECU: pressure monitoring, regeneration and the related fault codes and limp mode are disabled so the ECU no longer expects the filter.
Who is GPF/OPF Off for?
Workshops with clogged or damaged filters on Euro 6d petrol cars, and motorsport or export builds where the filter is removed. The filter must be physically removed or gutted as well.
Which file do I need to upload?
A full read of the original ECU file. Cat Off and Lambda Off can be selected in the same upload.
How long does GPF/OPF Off take?
Typically 10-45 minutes when prepared by a tuner.
Is it reversible?
Yes. Flash the original file back when the filter is refitted.
Is GPF/OPF Off legal?
The filter is emission equipment; removal is not permitted on public roads in most countries. The service is for off-road, motorsport and export use at the workshop's responsibility.
