The EGR valve (Exhaust Gas Recirculation) is an emission control device designed to reduce NOx emissions to help towards the ever more stringent Euro Emission Regulations. Celtic Tuning EGR Delete and EGR bypass software is designed to remove the functionality of the EGR valve to ensure it removes the running issues associated with these devices.
As the EGR valve is constantly working with burnt exhaust gases they naturally have high soot content. This soot in the gases causes a build-up of carbon deposits around the valve operation area which in turn causes the valve to have a tendency to stick in various positions. For full engine performance the EGR valve is closed which creates a closed loop environment for the turbo system which allows it to pressurise. A problematic EGR can create an open loop environment for the turbo as it provides a feedback straight to the intake manifold and as a result can cause boost issues along with huge reductions in power and also fuel economy!
