DPF–FAP OFF Service
DPF OFF (Diesel Particulate Filter Delete) is an advanced ECU remapping solution designed to completely disable the Diesel Particulate Filter (DPF/FAP) system via software.
At AutoExplain, we provide professional DPF OFF ECU remap services for workshops, performance tuners, and diesel vehicle owners who experience persistent DPF issues or require off-road / motorsport configurations.
DPF-FAP OFF Support for Multiple-Brand
DPF–FAP OFF meaning
WHAT IS DPF OFF (DPF DELETE)?
The Diesel Particulate Filter (DPF) is designed to trap soot particles in the exhaust system and periodically burn them through a regeneration process.
Over time, DPF systems commonly cause serious drivability and reliability issues, including:
Repeated or failed regeneration cycles
Persistent DPF fault codes
Limp mode (engine power limitation)
Oil dilution caused by post-injection
High exhaust backpressure
Reduced turbo efficiency
Increased fuel consumption
Engine and turbo stress
DPF OFF via ECU remapping permanently disables all DPF-related strategies, allowing the engine to operate smoothly without regeneration attempts or DPF-related errors.
