DTC Fault Code P2031 (EGT: datchik temperatury vykhlopa 2 — tsep) — DTC Fault Meaning, Limp Mode & ECU Firmware Deactivation (DTC OFF)

Search by diagnostic scanner fault code (e.g., P226D09, P2002F0, P24AEF2, P0401) to see which ECUs and calibration map packs (.KP / .A2L / .OLS) include verified DFC mask offsets for limp-free deactivation.
