What is the DPF and is it worth doing a DPF Delete?
Most post-2007 diesel vehicles are fitted with a Diesel Particulate Filter (DPF) For emissions reasons, however there are a few disadvantages to this device; including constant maintenance and repairs.
Because the DPF clogs up, it increases backpressure. Due to this pressure, the fuel flow is hugely disturbed and slowed down. ThereFore, when you remove this filter, the fuel flows much easily and faster, increasing the overall fuel mileage.
