Diesel Particulate Filter Solutions - DPF Doctor agents for Norwich
Diesel particulate filters, generally known as DPF, have been fitted to modern diesels since approx 2008 to reduce soot particulates and to predominately meet stricter emission levels. Whilst they do a good job problems can occur causing them to block prematurely. When this happens, you will usually get a warning light on the dash signalling a problem either by a DPF light and/or an engine management warning light.
The DPF doctor network consists of independent DPF specialists that can accurately diagnose your DPF problem and any underlying faults that have caused the problem .We will advise you of the reason for your DPF problem , fix it and then give you some honest advice on how to get the best out of your DPF vehicle . We carry a vast range of diagnostic tools many at dealer level and have completed the DPF Doctor advanced training course .
Stage 1: In Depth DPF Diagnostics
We carry out an in depth diagnostic, checking the key components and sensors are functioning correctly before initiating a DPF clean. Where necessary, further investigation is carried out to ensure a successful clean.
Stage 2: The DPF Cleaning Process
Using our specialist cleaning system, a carbon cleaning solution is injected into the pre DPF pressure line and a 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 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 road tests 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.
