EEC & National Autoparts offer advice on changing DPFs

European Exhaust and Catalyst (EEC) in association with National Autoparts took to the road this week to offer mechanics and technicians best practice advice on changing a Diesel Particulate Filter (DPF).

EEC and National Autoparts held a training night at the Castletroy ark Hotel in Limerick on Tuesday Night and gave the assembled audience a run down on best practice advice on changing a Diesel Particulate Filter (DPF).008 Stuart Still of EEC told the assembled audience that a Diesel Particulate Filter (DPF) is a service item and will need to be replaced at the end of its life. This will vary by vehicle manufacturer and the how the vehicle is maintained.

If the DPF needs replacing due to blockage, this would usually be the result of an electrical or mechanical fault upstream, which includes: Turbo wear, engine wear, contaminated air filter, fuel injector & glow plug faults

Blocked DPFs will not be credited under warranty. It is imperative to correct/fix any upstream fault prior to the new DPF being fitted, otherwise it is likely the original fault will reoccur.012 When a replacement DPF is fitted, the ECU must be reset and a forced regeneration cycle carried out. The fuel additive should also be topped up to the recommended level. This must be completed by a competent technician using the correct software/equipment for the vehicle.
