GPF and OPF off explained

What a GPF or OPF does

Direct-injection petrol engines can produce fine soot. A GPF or OPF traps it before it leaves the exhaust.

Like a DPF, the filter loads over time and the ECU runs regeneration cycles to burn the soot off. Short, low-load driving is the most common cause of a loaded filter.

What a GPF or OPF off file changes

A GPF or OPF off file changes how the ECU monitors and regenerates the particulate filter, so the system is not reported as faulty when it is not in use.

It does not remove the filter, clean soot or repair a damaged filter. BRV Tuning supplies the binary only.

Emissions-related files are supplied for off-road, competition, agricultural and export use only, and must not be used on public roads.

Common codes

• P2002Diesel particulate filter efficiency below threshold (Bank 1). The ECU estimates the DPF is not trapping soot as well as expected.
• P2463Diesel particulate filter soot accumulation. The ECU estimates a high soot load in the DPF.

Symptoms people usually report

• Frequent regeneration and warning lamps on petrol cars with short journeys.
• A particulate filter fault after a catalyst or filter change.
• Higher fuel use during regeneration cycles.
