DPF in Bishopsworth, Hartcliffe, Hengrove and all Locations in the Bristol Area

If you live in the Bristol area and drive a modern diesel model, it will have a DPF fitted to the exhaust system. The DPF (diesel particulate filter) has been a common feature on mass-produced cars for around two decades and, in compliance with Euro 5 exhaust emission regulations, having one fitted has been mandatory since 2009. The purpose of this legislation was to reduce the CO2 emissions released into the atmosphere to help the environment.

24/7 Auto Repairs can offer DPF cleaning services in the following areas:

Bishopsworth | Hartcliffe | Hengrove | Keynsham | Knowle

We also offer a DPF repair, replacement and regeneration service.

DPF inspections were introduced into MOT testing in 2014, so we have made adaptations to our services to accommodate work on this essential exhaust system component. By evaluating stored fault codes through our diagnosis service, or by troubleshooting in the event of a customer noticing a physical issue, we determine the extent of a problem and recommend a repair.

Cleaning the DPF is usually the most frequent outcome.

What is a DPF (Diesel Particulate Filter)?

The DPF is a component that traps soot to reduce the exhaust’s emissions to stop it from becoming blocked. It captures and holds the soot produced and, during combustion at a high temperature, reduces this soot to ashes as part of a regeneration process. Regeneration is important because the filter only has a limited capacity. Blockages can impact how the DPF performs.

Common indicators of a blocked DPF include:

  • A warning light on your car’s dashboard
  • Sudden drops in engine power
  • A noticeable smell of diesel
  • Sudden increases in the oil level
  • An excess of smoke coming from the exhaust

If any of these issues arise, we recommend that motorists in the Bishopsworth, Hartcliffe, Hengrove, Keynsham and Knowle areas book in for DPF cleaning at 24/7 Auto Repairs at the earliest available opportunity.

What Causes the DPF to Block?

Because the DPF only has a limited storage capacity, good regeneration is a critical process that stops the filter from becoming blocked. Regeneration has two stages, referred to as passive and active regeneration. During passive regeneration, driving at higher speeds over longer distances will increase the running temperature and the heat generated burns off captured soot.

During active regeneration, the engine management system injects an extra amount of fuel into the exhaust system once stored soot levels reach pre-set limits. This raises the running temperature to kickstart regeneration and burns off stored soot. If your diesel model has a blocked DPF, passive and active regeneration won’t be efficient enough to complete the process.

This is the point when booking in for DPF cleaning becomes advisable.
