What problems can a DPF cause?

Because a DPF blockage directly affects your exhaust system and its ability to remove gas from your engine, this then stops your engine from working as powerfully and as efficiently as it could. This in turn makes the diver heavier on the gas, which burns through fuel quicker and contributes to the engine suffocation.

Can you ignore the DPF light and carry on driving? Technically yes, but we would not recommend it. If you ignore the DPF light and continue driving, the build-up of soot will soon reach a point whereby your car has to enter ‘limp-home’ mode in order to prevent any damage to the engine.

Can a blocked DPF damage turbo?

A blocked DPF can force exhaust gas through the smallest of gaps, including the clearances in the bearing housing VNT lever arm and turbine housing waste gate mechanisms. If this occurs, carbon build up in these mechanisms can restrict movement of the levers affecting performance of the turbo.
