EGR stands for Exhaust Gas Recirculation. The purpose of it is to regulate the flow of exhaust gases further minimising the amount of Nitrogen Oxide the car produces. The EGR operates by reabsorbing some of the exhaust gas into the engine cylinders. This is done at the same time that oxygen intake is decreased by the intake valve; thus reducing Nitrogen Oxide.
The EGR will naturally have a lot of soot deposits in it as it constantly deals with burnt exhaust gases. As the soot deposits build up, it can have repercussions on your vehicle. There will be a loss of power, slower acceleration and throttle response.
When the exhaust gas recirculation valve gets blocked, it can affect your vehicle. The engine may overheat as the valve is blocked and the engine will need to work harder to make up for that. If not sorted soon, the blocked EGR valve can affect the performance of the car and potentially damage the engine.
When a blockage in the DPF occurs, your vehicles will notify you with an orange light shaped like the DPF on your dashboard. When this light displays, we advise that you seek assistance from a vehicle technician as soon as you can.
Having your exhaust gas recirculation valve removed will offer your car plenty of benefits. You’ll notice an increase in performance along with better miles per gallon and lower engine temperatures.
