DPF Diagnostics and Fault Finding
DPF warning lights are often symptoms, not root causes. We diagnose the system before recommending cleaning, regeneration or ECU work.
What We Check
- Soot load and ash load data where supported
- Differential pressure readings
- Exhaust temperature sensor values
- Failed regeneration history
- Related EGR, boost and fuelling issues
Why Diagnosis Matters
Forced regeneration or cleaning may not last if the vehicle still has a faulty sensor, short-journey driving pattern, thermostat issue or failed regeneration logic.
