The EGR (Exhaust Gas Recirculation) valve helps lower the car's exhaust emissions (gases from the tailpipe). It recirculates a portion of the gasses coming out of the engine by feeding them back in via the intake manifold, where the engine can burn them again, thereby reducing the emissions.

The result of this is a cooler, more complete burn of the fuel which decreases your car's noxious emissions by stopping the formation of some harmful gases.

How do I know if it is faulty or blocked?
If your EGR valve is faulty or blocked, you can experience some of the following symptoms:
• Engine Lamp (MIL) On in Check Control or “Reduction in Engine Power” displayed
• Lack of power
• Irregular engine idle or hunting
• Increased fuel consumption

You then begin to pollute the atmosphere with exhaust gases that your car is normally not dumping into the air.

What can be Done?
A faulty Exhaust Gas Recirculation valve and EGR Cooler should be cleaned or replaced as soon as possible. Sometimes this blockage can be caused by an unfavourable driving profile and the complete intake system can become blocked by excessive deposits of carbon.

At Turner Automotive we are experts at diagnosing and repairing EGR valves and Coolers. We have seen every type of failure regarding this system and use the latest technology and diagnostic equipment in assisting us with localising the defect in the air mass system to get your car back on the road and running as well as when it left the factory.
