WHAT IS AN EGR VALVE?
Exhaust Gas Recirculation (EGR). This device recirculates a proportion of the engine’s exhaust content into the intake air. A valve is usually used to control the flow of gas, and the valve may be closed completely if required.
EGR REMOVAL SERVICE
At AutoSphere we use an advanced method for EGR removal. The valve can become clogged over time, causing the valve to stick open or closed and will cause hesitation in the lower end of the engine revolution range, thereby causing error codes and the vehicle not to run correctly.
EGR REMOVAL BENEFITS?
Modern engines recirculate some of their exhaust gases back into the engine to reducing emissions. This is the is the main function of the EGR system. The downside is that exhaust fumes containing carbon deposits are constantly being recirculated through the engine through time causing a build-up of carbon deposits in the intake manifold etc.
Carbon deposits will contribute to the failure of the EGR valve. Replacement EGR valves are expensive and in the case of high mileage engines the carbon build up can eventually lead to total engine failure.
Removal of the EGR system by blanking off the exhaust input and reprogramming of the engine management ECU results in lower engine temperatures, improved throttle response and economy and also can lengthen engine life by reducing oil contamination and carbon deposits.
IS IT LEGAL?
At present it is not illegal to remove the EGR valve and it doesn’t form part of the MOT test. Whether this might be tightened up in the future, no one knows and our best guess that even if it is, then it will not be applied retrospectively.
Since the EGR system recirculates a portion of exhaust gases, over time the valve can become clogged with carbon deposits that prevent it from operating properly. Clogged EGR valves can sometimes be cleaned, but replacement is often necessary if the valve is faulty.
