DPF Cleaning

All post 2009 Diesel vehicles are fitted with a DPF (Diesel Particulate Filter) to comply with Euro 5 regulations.  Your vehicle produces soot when the engine is running and this is trapped in the DPF.  When a vehicle is on a longer run the vehicle will regenerate and burn off the soot to clean it which will result in ash being left in the DPF.  Over a period of time this will fill/clog up the DPF meaning it will need to be cleaned out.

If the DPF is becoming clogged with soot or a fault develops in the system, an orange light will typically appear on the dashboard.

They usually look like this with a piped box that has dots in the middle, although they can slightly vary by manufacturer manufacturer – check your handbook for more information

A 2 stage Cleaning process is used where firstly a chemical is left in the DPF to dissolve the ash/soot before cleaning. The second stage is a treatment that helps to restore the coating on the DPF ceramics ensuring your DPF lasts which is used before installing onto the vehicle.
