DPF SOLUTION

DPF or Diesel Particulate Filter, is a filter fitted to diesel vehicles exhaust systems past 2009 under new 'Euro 5' standards that were introduced in an aim to reduce pollution. Unfortunately with vehicles that are not driven on long journeys often, the DPF can cause major issues as they don't have a chance to regenerate and can block up if active regeneration instructed by the ECU doesn't complete fully.

A warning light related to the DPF can be scary, as replacing the DPF can be very costly, and if your driving style doesn't change you are likely to get problems again not to long after. We have alternative solutions which not only will fix the problem for good, but also give your vehicle a new burst of life when topped off with a Crown Performance Re-Map.

DO THEY REQUIRE MAINTENANCE?

A DPF has a design life of around 75,000 miles but this can be subject to large variation depending on vehicle use and engine condition. Every time the ECU forces a regeneration cycle it burns the particulate matter down to a much smaller amount of finer soot, they don’t get completely removed from the filter. Over time, the fine soot content builds up to a point where a regeneration cycle is no longer able to be performed; at this point the filter either needs emptying or replacing.

Removing the DPF is often advised to check the opacity of the exhaust emissions which can give some indication of any potential running issues which can impact on the operation of the DPF. Issues such as leaking injectors and engines burning oil can massively reduce the life of a DPF.

COMMON CAUSES FOR DPF FAILURE

There are a multitude of reasons a DPF can fail, the most common are highlighted below:

  • High mileage and compacted with fine soot
  • Failed sensors preventing DPF regeneration
  • Lack of additive in fuel (where fitted) causing incomplete burn off
  • Engine issues i.e. leaking injector, valve stem oil seals, worn piston rings
  • DPF unable to regenerate due to driving conditions i.e. City centre
  • Poor performance tuning
  • Driving in too low of a gear on a motorway disallowing the regeneration to commence
