What is EGR valve ?

The EGR valve works by recirculating a measured amount of the exhaust gases back into the engine through the air intake system, reducing the amount of emissions the engine produces.

The problem lies with the exhaust gas that contain carbon deposits, this gas is constantly being recirculated through the engine, which over time will cause a build-up of the carbon deposits in the intake manifold and other parts including the EGR valve. This build up in the valve is often what causes them to fail. 


EGR Valve Fault Symptoms :

  • Loss of power
  • Higher fuel consumption 
  • Reduced throttle response
  • Limp Mode


EGR Removal

Some cars may have a different EGR Valves or ones that are built into the inlet manifold. If this is the case we can still remove the EGR using blanking plates or in some vehicles changing the inlet manifold allowing fitment of our EGR Delete Race Pipe Kits.

Once the valve is either removed or blanked off the vehicles ECU will no longer get a signal from the EGR Valve causing the emissions workshop light to appear on the dash board. We can remove this by reprogramming the EGR software on the ECU.



For cars which still have DPF we wouldn't recomend to remove EGR valve. It could cause problems in future if not removed together. See DPF removal
