GPF / OPF Off

GPF / OPF Off explained — how it works, related DTCs and how Softechpro does it with automatic checksum correction.

What is GPF / OPF Off?

Modern Euro 6d petrol cars (VAG 1.5/2.0 TSI, BMW, Mercedes) use a GPF/OPF. GPF/OPF Off removes its monitoring and regeneration logic from the ECU map. Softechpro applies it directly in the ECU calibration and recalculates the checksum & CVN automatically, so the file is flash-ready. Typical related codes: P2BAD, P244A (petrol), P0420.
