The Exhaust Gas Recirculation (EGR) helps a modern diesel engine warm up quicker at lower temperatures and helps the engine run efficiently with lower emissions. In time the EGR may become inefficient and you will be left with two options either EGR removal or replacement, EGR removal being the relatively inexpensive choice.
When the EGR clogs up with carbon it reduces the flow of air through the intake system causing a reduction in power and fuel efficiency making an EGR removal a great money saving exercise. Deposit pieces of carbon may flow back into the intake causing problems within the engine a EGR removal will prevent this.
Just removing the EGR will cause problems like lack of power, poor engine running or ECU fault lights. Performance Blue will remove the EGR and remap your ECU preventing future problems.
Performance Blue provide the EGR removal in Manchester area and is a great way to keep your car running smoothly.
What does Wiki say about EGR removal?
By feeding the lower oxygen exhaust gas into the intake, diesel EGR systems lower combustion temperature, reducing emissions of NOx. This makes combustion less efficient, compromising economy and power. The normally “dry” intake system of a diesel engine is now subject to fouling from soot, unburned fuel and oil in the EGR bleed, which has little effect on airflow. However, when combined with oil vapor from a PCV system, can cause buildup of sticky tar in the intake manifold and valves. It can also cause problems with components such as swirl flaps, where fitted. Diesel EGR also increases soot production, though this was masked in the US by the simultaneous introduction of diesel particulate filters. EGR systems can also add abrasive contaminants and increase engine oil acidity, which in turn can reduce engine longevity.
Though engine manufacturers have refused to release details of the effect of EGR on fuel economy, the EPA regulations of 2002 that led to the introduction of cooled EGR were associated with a 3% drop in engine efficiency, bucking a trend of a .5% a year increase.
