Regeneration possible
If the vehicle is safe to regenerate and the underlying cause is resolved, a forced regeneration may be suitable.
DPF diagnostics before expensive parts.
We use fault codes, live data and physical checks to work out why the DPF warning light is on before recommending cleaning, repair, renewal or software work.
What we check
A blocked DPF is often caused by something upstream. The diagnostic work looks at the whole system rather than treating the filter as the only fault.
- Differential pressure readings and pressure pipe condition
- Soot loading, ash loading and regeneration status
- Exhaust gas temperature sensors and plausibility
- EGR, boost, injector, thermostat and air-leak faults
- Previous software files, adaptation values and incomplete repairs
Bring useful details
Registration, mileage, warning message, recent work and any fault codes help us prepare before the vehicle arrives.
Send vehicle detailsTypical diagnostic outcomes
The right next step depends on measured data and the condition of the filter.
Cleaning recommended
Where the filter is blocked but physically sound, off-car cleaning may restore flow.
Repair or renewal needed
Sensor faults, split pipes, cracked filters, melted cores or high ash loading need a different approach.
