DPF Diagnostics Wales

Find the fault before fitting parts.

We diagnose DPF warning lights, limp mode, failed regenerations, high soot load, differential pressure faults and sensor problems across Wales.

DPF fault finding that makes sense.

DPF problems are rarely solved by guessing. We read the vehicle, check live data and look at the conditions needed for regeneration before recommending cleaning, repair or software work.

  • Differential pressure sensor and hose checks
  • Soot load, ash load and back-pressure readings
  • Exhaust temperature and regen enable conditions
  • EGR, injector, boost, thermostat and glow plug faults
  • Previous software changes and failed file checks

Warning light on

We identify whether the filter is genuinely blocked or whether a sensor, pipe, wiring or engine fault is causing the warning.

Regeneration will not start

Many vehicles block regen when another fault is present. We check the conditions and data before forcing anything.

Limp mode

High exhaust back pressure and sensor faults can both trigger restricted power. The right reading matters.

Repeated DPF faults

If the fault keeps returning after a clean, we look for the root cause and any software issues.
