The DPF is simply a filter, there are many reasons it can clog up. The most common myth is that it’s
clogged because of driving only in the city and not on the motorway. Although this can be a cause
there is more often than not an underlying fault that has caused the DPF to clog up. It’s is
therefore imperative that a correct diagnosis is made and any faults are repaired that could
impede the DPF system from working correctly. Assuming all faults are resolved then yes
cleaning the DPF will resolve the DPF.
