DPF
Services
DPF fault diagnosis, forced regeneration, and ECU programming for diesel cars, vans, trucks, and commercial vehicles. Accurate diagnosis before any recommendations.
DPF Faults Explained
The Diesel Particulate Filter captures soot particles produced during combustion. A built-in regeneration process burns off accumulated soot by briefly raising exhaust temperatures. If regeneration cycles repeatedly fail — due to short journeys, sensor faults, or related system issues — the filter becomes overloaded and the DPF warning light illuminates.
Not every DPF warning light means the filter is mechanically blocked or needs replacement. Many faults are caused by failed temperature or pressure sensors, EGR problems preventing regeneration, or fuel system issues. Diagnosis first — before any parts are ordered or replaced.
ECUFLASH carry out DPF diagnostics using manufacturer-specific equipment, giving us access to live DPF soot load, ash load, differential pressure, and temperature data — information not available on generic OBD readers.
