Diesel Particulate Filters (DPFs) first appeared 30 years ago and became compulsory on all new diesel vehicles in 2009 to meet ‘Euro 5’ emissions standards. 80 to 95 per cent of the harmful particles contained in diesel exhaust are captured in a cordierite, silicon carbide or ceramic matrix core. However, many drivers are ignoring the maintenance of their DPFs, costing them much more than necessary in the long run.
Short journeys and stop-start driving are strongly associated with DPF blockage and prevent DPF ‘regeneration’, a process that burns the accumulated soot.
Since February 2014, the MOT test has required a visual inspection to check the DPF is present, however, an undercover BBC report in Staffordshire last year found that five out of ten garages offer to remove or modify the DPF.
Jagdish Parmer, Director at 4.2 Motors, London said: “We get a lot of minicab drivers that have come from different garages that would start changing DPFs and we find that they have not been diagnosed right.”
Importantly, many DPF problems can be averted by using pour-in treatments. This reduces the need for the DPF to be sent away for specialist cleaning, or more often complete DPF replacement, which can cost in excess of £1,000.
AMS offers a range of DPF treatments which save our customers ££££s on specialist cleaning.
