DPF Repairs Wales
Repair the fault that keeps blocking the filter.
DPF repairs for sensors, split pipes, wiring faults, EGR issues, injector problems, thermostat faults and failed regeneration causes.
DPF faults often start elsewhere.
A DPF warning can be the end result of an engine, exhaust or sensor problem. We focus on the cause: the data that stops regeneration, the parts giving false readings, or the engine condition filling the filter too quickly.
- Differential pressure sensors and blocked or split hoses
- Exhaust gas temperature sensors
- EGR and boost control faults
- Injector, glow plug and thermostat faults affecting regen
- Software correction after poor previous work

Sensor repairs
Bad readings from pressure and temperature sensors can make the vehicle think the DPF is blocked or stop regen altogether.
Pipe and wiring faults
Split pressure pipes, blocked tubes and wiring faults can cause repeat warnings even after a clean.
Engine faults
Boost leaks, EGR faults, injector issues and low temperature running can load the DPF quickly.
Failed previous repairs
We can inspect vehicles that have already had a clean, sensor or software file but still have problems.
