DPF Failure Causes / Awareness A diesel particulate filter (DPF) is a device designed to remove diesel particulate matter or soot from the exhaust stream. DPFs are only covered for structural failure, a particulate filter returned due to blockage will not be considered as a warranty claim.

ADVICE FOR DIESEL PARTICULATE FILTER CARE • When the EML warning light illuminates you must follow the instructions in the owners handbook immediately. Failure to comply could lead to a blocked DPF. • Active DPFs that use additive (Eloy’s Fluid) to assist in regeneration must never be driven without this fluid, as this could result in a blocked DPF. • When fitting a new DPF or topping up the additive the control unit must be reset to new DPF / refilled additive. • It is not advisable to run a DPF vehicle on bio-diesel.

REGENERATION WILL NOT TAKE PLACE WHEN • The fuel light is on, or there is less than quarter of a tank of fuel • If the engine management light is on • If your foot is resting on the clutch pedal
