Leading provider of reman engines and remanufacturers of all major units, Ivor Searle, has introduced a professional Diesel Particulate Filter (DPF) cleaning service for car and light commercial vehicles.

Utilising state-of-the-art Flash Cleaning technology, the environmentally-friendly process delivers as new levels of cleanliness by removing all soot deposits, including PM10 particles, cerium oxide deposits and oil residues, from the DPF. 
 
Ivor Searle’s fast turnaround professional DPF cleaning service gives independent workshops a competitive advantage by enabling them to offer their customers a low-cost alternative to component replacement. To guarantee peace of mind, all Ivor Searle cleaned DPFs are provided with a detailed inspection report and are covered by a no-quibble, 12-month unlimited mileage warranty.
 
What is a DPF and why do they get blocked?
 
A Diesel Particulate Filter (DPF) is designed to reduce the soot emissions from a vehicle’s exhaust systems by up to 80%.  The introduction of Euro 5 emissions legislation saw DPF technology became mandatory for all diesel vehicle type approvals from September 2011 and new cars from January 2013.  As a result, MOT testing stations have had to check for a DPF in the inspection of the exhaust system as part of the MOT test since February 2014.
 
DPFs work by trapping bits of soot from incomplete combustion in the exhaust system.  The DPF is structured like a series of honeycomb filters that prevent the soot passing all the way through the filter into the atmosphere, thereby reducing emissions.  Unfortunately, DPF blockages have become common in low mileage vehicles used in urban driving cycles.
 
DPFs are designed to effectively self-clean in a process called regeneration where the soot is burnt off the filter at a high temperature, typically when a vehicle is travelling consistently at moderate to high engine speed.  However, if a vehicle is frequently used to travel short distances, the vehicle is unlikely to produce the exhaust temperatures required to enable regeneration to take place, resulting in excessive soot build up and a drastic reduction in vehicle performance.

Analysis by Umicore, one of the world’s foremost automotive DPF and catalyst manufaturers, has confirmed that there are no remarkable differences between a DPF cleaned using the same technology employed by Ivor Searle and installing a brand new unit.
