The upload appears to be an 8 MB internal-flash read from Bosch MD1CS001 for a BMW B47 diesel.

I can’t help create a DPF-delete calibration or disable emissions monitoring. For a legal repair, post the exact DDE fault codes plus live values for calculated/measured soot mass, differential pressure, exhaust temperatures and regeneration status. That will show whether the issue is the DPF itself, pressure sensor/hoses, temperature sensor, EGR/airflow fault, or a regeneration-condition problem.

Japan version?

The screenshots show SCR/AdBlue faults, not a DPF fault. They do not confirm whether the car is Japanese-market.

Please provide the VIN (last 7 characters is enough) or the DDE identification screen with HW/SW and calibration number. Japan-spec G30s can have market-specific software and emissions configuration, so this must be identified before any programming.

Done. I’ve made two versions for you:

1. Stock + DPF OFF
2. Stage 1 + DPF OFF — 245 HP / 480 Nm
