What to do if you have an EGR fault?
When presented with an EGR valve fault, At M B Jarvie Ltd we offer our customers the repair option of renewing or removing the EGR valve. Modern EGR valves are often buried in the engine bay and renewal can be very expensive (factoring in both parts and labour).
What happens if the EGR valve is open all the time?
If the EGR valve stays open at all times and the exhaust fumes are being fed to the engine constantly, the engine gets deprived of oxygen. With too much fuel burning and less oxygen, a black smoke gets produced and escapes from the exhaust pipe especially when the car is idle.
Is the EGR valve in the engine bay?
Modern EGR valves are often buried in the engine bay and renewal can be very expensive (factoring in both parts and labour). The EGR valve operates in a harsh environment and it therefore prone to failure. We therefore offer our customers the option of removing the EGR system from the engine management programme.
Can a blanked off EGR improve engine performance?
Of course its not. The EGR pumps warm used air back into the engine instead of cold clean air. If you were to blank of the EGR, it would continuously get cold air thus an improvement in performance. For people looking for the best performance upgrade (such as myself), a remap with a blanked off EGR will provide excellent results.
What is the purpose of the EGR valve?
The purpose of the EGR valve is to reduce the pollutants that are put out from the exhaust of your vehicle in an effort to reduce greenhouse gases and other toxins. In particular, the EGR valve helps reduce something called nitrogen oxides. Your car engine is designed to burn very hot, round to 2,500 degrees Fahrenheit.
How can I tell if my EGR valve is not working?
Poor Emission Test Results: A good sign that your EGR valve is not working properly is if you go in for an emissions test and it shows that you have nitrogen oxides in your exhaust. Not every vehicle is subject to an emissions test, and some states don’t require you to do them at all.
How does the EGR valve affect Wot performance?
It has absolutely 0 effect on WOT performance and I’ll explain why in this article as well as tell you how clever this little valve really is. The EGR valve does not open under heavy load (I am unaware of any exceptions) and therefore, you will not be burning exhaust gasses while at wide open throttle.
Can a new gasket be installed on an EGR valve?
If it’s questionable, install a new one. We recommend installing a new gasket with any repair. Cleaning the EGR valve assembly is a two-step process. It depends on how far you want to go and how much time you have. First, soak the EGR valve in a bowl filled with carb cleaner.
