Warning light on? DPF light flashing or solid Reduced power / limp mode Poor MPG or failed regen Book diagnostics

Why the filter blocked matters more than the warning light.

Replacing or cleaning the DPF can be wasted money if the underlying fault remains. Low exhaust temperature, split pressure pipes, poor boost control, EGR faults, injector issues, thermostat problems and sensor faults can all bring the same warning back.

We ask for the registration, mileage, dashboard message, fault codes and previous work because that shortens the route to a sensible answer.

Common reasons customers get in touch

If any of these sound familiar, send the vehicle details and what has already been tried.

DPF light or limp mode

High back pressure, blocked regeneration or a sensor fault can put the vehicle into reduced power.

Cleaned but blocked again

If the upstream cause is still present, a clean filter can load up again quickly.

DPF removal or delete enquiry

We can discuss DPF removals, DPF delete software, economy remapping or performance remapping and check whether the vehicle and job are suitable before work is booked.
