DPF Cleaning in Birmingham

Diesel Particulate Filters trap soot before it reaches the exhaust. They are designed to clear themselves through a process called regeneration, typically triggered by sustained motorway driving. Short journeys, urban driving and faulty sensors all stop that process happening properly, and the filter slowly fills up.

Once the filter is blocked beyond a certain point, the car drops into limp mode, the warning light comes on and standard regeneration cycles will not recover it. That is the point where it needs a proper clean, not another forced regen attempt.

We start with a diagnostic scan and a pressure differential reading to confirm the filter is genuinely blocked rather than the sensor being faulty. Where the filter is salvageable, we run a controlled clean and regeneration cycle and verify the result with a second pressure reading.

If the underlying cause is a sensor, an injector or a faulty EGR feeding excess soot into the system, we tell you. Cleaning the symptom without addressing the cause just buys you a few months.
