Diesel Particular Filters Explained

A Diesel Particular Filter (DPF) is easily described as a filter within the exhaust of most modern diesel vehicles post 2005. The filters job is to reduce emissions by collecting them in the soot which exits the vehicle via the exhaust. The car is then programmed to perform a 'Re-gen' or 'Regeneration' to clear the filter, preventing it from blocking up with soot. However, there are many reasons as to why vehicles don't do this which is what causes this filter to become blocked. Examples of these are EGR faults, Engine Fault Codes, Short Journeys, Low Fuel and many more.


It is key to understand why the DPF has become blocked before changing, cleaning or deleting it. We carry out extensive diagnostic work to find the route of the issue before proceeding. Whilst you can clean or replace a DPF at a greatly cost, by hollowing out the filter and mapping the software to suit, we provide a solution which is guaranteed to have no returns from the client.

Exhaust Gas Recirculation Valves Explained

EGR Valves or Exhaust Gas Recirculation Valves are fitted to vehicles made after 2000 and are designed to reduce emissions to meet certain manufacturer requirements. They do this by taking gases which are exiting the vehicle via the exhaust, and before they do so, pump them round to the front of the engine, to the air inlet, to be burnt through again. The theory behind this is the gases get burnt twice, and therefore when the final emissions are leaving the exhaust are reduced.

However, in practice EGR Valves are common to failure due to the type of gases and carbon deposits which pass through them. EGR's are commonly blocked with a thick build up of carbon, to the point where the valve doesn't move/operate in the correct way. The consequences of this are; inefficient and rough running of the engine (especially on low revs or start up), DPF issues, Engine Management Lights, Limp Mode and many more.

So now you wondering why blank and delete your EGR? First of all EGR Valves are expensive to replace, parts are costly and hours of labour is needed in the process, and this doesn't guarantee the problem won't return. By blanking and mapping out the EGR, we guarantee a solution to an EGR nightmare.

In addition to this, the fundamental design of an EGR Valve is to put all the soot, carbon, and gases leaving the vehicle back through your engine. This causes harmful build ups on engine components, shortening their lifespan as well as the issues listed above. By blanking the EGR, the gases are prevented from recirculating which makes for a much cleaner, smoother running engine and pro-longs the components.
