EGR Off
EGR is a shortcut of Exhaust Gas Recirculation. The system is used in cars equipped with an internal combustion piston engine. It was designed to reduce pollutions in combustions gases. The main reason for putting through this solution was the growing number of toxic pollutants emitted by cars.
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.
What is an EGR Valve?
The problem lies with the exhaust gas that contains 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.
What is an EGR Cooler?
The EGR Cooler is designed to lower the temperature of the exhaust gases before they are recirculated back into the engine. This is done to keep the inlet air temperatures as low as possible. These are known for cracking which normally results in coolant loss. Later model Common Rail Engines have flaps and solenoids on the Coolers, as well as sensors to monitor its operation. When these fail, fault codes and warning lights may also be triggered.
Symptoms and Fault Codes
There are multiple faults codes and symptoms that can point towards a faulty / blocked EGR Valve and Cooler
Valve Fault Symptoms:
- Loss of power
- Lower fuel consumption
- Reduced throttle response
- Limp Mode
- Engine Management Light
- Flashing Glow Plug Light
- Fault Codes
Valve Fault Symptoms:
- Loss of Coolant
- White Smoking
- Poor Running
Warnings:
- Engine Management Light (Later Common Rail Engines)
- Flashing Glow Plug Light (Later Common Rail Engines)
- Fault Codes
EGR Off Files
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 dashboard. We can remove this by reprogramming the EGR software on the ECU.
- Lowered Engine Temps
- Improved Throttle Response
- Improved Economy
- Reduces Oil Contamination
- Reduces Carbon Deposits in the engine
Please Note:
The EGR Valve should NOT be removed on vehicles that still have the DPF Filter in place, doing so may block the DPF as the EGR Valve operation is a prerequisite for DPF Regeneration.
