Service Overview

Exhaust Gas Recirculation is a system designed primarily to reduce nitrogen oxide emissions from internal combustion engines, but a quality EGR system properly fitted can also increase engine efficiency. EGR is a required feature on most modern internal combustion engines.

EGR works by recirculating a portion of an engine's exhaust stream back into the engine, optimising the incoming flow of oxygen and providing inert gases that absorb some of the heat generated by the combustion process. Because EGR is now a legal requirement, faulty EGR systems will need to be replaced as soon as possible.

Frequently Asked Questions

EGR stands for Exhaust Gas Recirculation and it is a function performed within the combustion engine of a car. The measure recirculates exhaust gases back into the inlet manifold to be used for combustion again. The reason that EGR takes place is to reduce the production of oxides of nitrogen which is harmful to breathe in and is damaging to the environment.
Yes, one of the first symptoms of a problem with the EGR valve is engine performance issues. A clogged or malfunctioning EGR valve can disrupt the vehicle's air-fuel ratio, which can cause engine performance issues such as a reduction in power, acceleration, and even fuel efficiency.
Yes, when the EGR valve is clogged or dirty, as they are prone to, it may not function properly causing the engine idle rough, stall at idle speeds, cause the car to get poor fuel mileage, or emit a strong smell of fuel due to excess hydrocarbons which also results in failing emissions tests.
  • Engine has a rough idle
  • Car has poor performance
  • Increased fuel consumption
  • Car frequently stalls when idling
  • Can smell fuel
  • Engine management light stays on
  • Reduced horsepower
  • Black smoke from exhaust
Yes, the EGR valve is an important component in the exhaust gas recirculation process as it helps to prevent exhaust valves from overheating, which can accelerate their wear and tear. The EGR valve therefore helps maintain the exhaust system at full capacity and increases the longevity of the internal combustion process.
