What is a DPF?
A diesel particulate filter (DPF) is designed to remove diesel particulate matter or soot from the exhaust gas on a modern diesel engine. After the accumulation of a minimum level of soot, a regeneration process injects diesel (or another fluid) to increase exhaust temperature high enough to combust the soot, leaving ash. This cycle continues for the filter's life.
What causes DPF issues?
A working DPF only slightly increases back pressure. Issues arise when regeneration cannot occur. Common causes include:
- System Faults. Any engine fault will prevent regeneration because the ECU closely monitors the process.
- Vehicle Driving. Regeneration needs minimum speed, temperature, and drive time. Short trips cause issues; longer commutes help.
- DPF Aging. Filters are service items. Cleaning or forced regeneration on an overdue filter may not help.

We believe diagnostics are key. We use ECU data and talk through your daily driving. During advanced diagnostics we look for:
- Engine DTC's or Fault Codes to pinpoint the issue or guide further diagnostics.
- Engine Electrical Live Data to ensure everything reads correctly for proper DPF function.
- Vehicle Daily Driving to understand if regular journeys allow regeneration.
