DPF diagnostics, cleaning, repairs and removals.
DPF warning light on? Limp mode? Failed regeneration? We help with blocked DPF faults, pressure sensor issues, soot loading, ash build-up and DPF software work for vehicles across Wales.
DPF Cleaning
Practical cleaning options for blocked filters, repeated regen failures and high back-pressure problems.

We find out why the DPF blocked.
A blocked DPF is often the result of another fault. Short journeys can play a part, but so can failed temperature sensors, pressure sensor faults, split pressure pipes, thermostat problems, boost leaks, EGR issues, injector faults, oil ash and bad software.
We check the vehicle properly and explain the cause, so you can choose the right fix instead of paying for the same warning light twice.

Workshop support
Cleaning, repairs and software work in one place.
Some vehicles need a clean, some need an underlying fault repaired, and some need specialist software work after repeat problems or poor previous files.
Tell us the vehicle, the warning message, the fault codes and what work has already been tried. We will point you towards the most sensible route.

When to get in touch
DPF warning light
Warning lights should be checked before the filter reaches a high soot load or the vehicle blocks regeneration.
Limp mode or low power
High back pressure, sensor faults, turbo control issues and EGR problems can all leave the vehicle down on power.
Regeneration keeps failing
We check temperatures, driving conditions, engine faults and live data to see why the vehicle will not complete a regen.
Filter cleaned but fault returned
If the root cause is still there, the DPF can block again quickly. Proper diagnosis saves repeat bills.
Tell us what the dash says.
Send the registration, the warning message, fault codes if you have them, and whether the vehicle is in limp mode. We will help you decide the next step.
