EAC Telford Limited - DPF Refurbishing Service

International leaders in diesel particulate filter refurbishment

Legal requirements and the MoT test February 2014
From February 2014, the inspection of the exhaust system carried out during the MoT test will include a check for the presence of a DPF. A missing DPF, where one was fitted when the vehicle was built, will result in an MoT failure.

EAC Telford Introduction

  •  International leaders in diesel particulate filter refurbishing services
  • Cleaned more than 100,000 DPFs in the last 10 years
  • Approved by Manufacturer’s
  • EAC Telford has been supporting DPF service exchange programs for many years
  • Patented cleaning process – very effective for removing both SOOT & ASH in one process

Benefits from using the EAC Telford

  •  Cheaper alternative to purchasing an OEM DPF or even some aftermarket options? Also fills the gaps where only an OEM DPF is available?
  • More effective than any other cleaning method
  • Improved fuel consumption arising from a cleaner filter
  • Chemical free process
  • A filter condition report with every refurbishment showing airflow performance and weight removed
  • A 6 months or 5000 mile no quibble warranty is offered (does not include labour) Chemical cleaners
  • Most if not all chemical cleaners, only remove soot and are designed to induce a regeneration of the DPF to take place at a lower temperature. ASH cannot be burnt off and needs to be physically removed from the DPF.

Vehicle DPF regenerations

  • A DPF vehicle regeneration will only remove soot, ASH has to be physically removed hence the reason for cleaning.
  • In some cases, the DPF light may go out after regeneration but come back on after a few miles, this is most likely because there is a build of ash and the regeneration is only removing the soot.

The DPF Cleaning Process:

Stage 1: In Depth DPF Diagnostics

We carry out an in depth diagnostics, checking that the key components and sensors are functioning correctly before initiating a DPF clean. Where necessary, further investigation is carried to ensure a successful clean. We carry various common DPF sensors, pipe’s etc in stock so that we can quickly have you back on the road in the event that your DPF problem is actually a component failure.

Stage 2: The DPF Cleaning Process

Using our specialist cleaning system, a carbon cleaning solution is injected into the pre DPF pressure line and soak period is now initiated. The engine is then ran at a fast idle allowing the soak fluid to clean the carbon content in the DPF. This is then followed by a further injection of a cleaning flush solution during an engine fast idle cycle and we carry out the flushing process twice.

Stage 3: Live Data and DPF Analysis

Finally, live data is analysed during a road test or DPF regeneration. This is then followed by final parameter checks logging DPF back pressure readings. These readings, before and after, are then reported back to you for your peace of mind. The three stage DPF cleaning process is now complete.

The whole process takes approximately 2 hours to complete.
