What causes a clogged EGR valve?
Usually, this is caused by a blockage and buildup of carbons. If the EGR valve is clogged, there is also a good chance the intake manifold is full of carbon as well. Some of the symptoms of a stuck closed EGR valve are pinging noise, tapping noise, and detonation noise, and a check engine light.
What is the purpose of EGR valve?
The function of the EGR valve is to reduce emission gases exhausted from the vehicle. The emission gas is recirculated back to the engine through the intake manifold to be re-burned in the combustion chamber. Normally, when the EGR valve is clogged, rough idle will occur.
