What to do if you have a bad EGR valve?
The first thing you do is to locate your EGR valve. You can take a look at the manufacturer’s guide of your vehicle to help you with this. Then put on your vehicle’s engine and rev your engine to about 2000 rpm. Gently create access to your valve and place your hand on it.
When does the engine check light turn on?
The engine check light will illuminate when there is a faulty in the EGR valve. This light will not turn on until your vehicle’s computer picks up a negative signal from your EGR valve or any other engine component. Anytime you see your engine check light on, carry out a thorough examination of your vehicle’s engine as soon as possible.
How does an exhaust gas recirculation ( EGR ) valve work?
The EGR (Exhaust Gas Recirculation) valve helps lower the car’s exhaust emissions (gases from the tailpipe). It recirculates the portion of the gasses coming out of the engine by putting in back into the intake manifold, where the engine can burn it again, thereby reducing the emissions. The EGR
What happens when your engine valve is clogged?
When your vehicle’s engine valve is clogged, making it unable to close or open, this will cause the exhaust gas to flow into the intake manifold of your vehicle before it is needed by the engine. This causes poor acceleration while driving.
Can you run an EGR test on a diesel engine?
Doing an EGR test as you would on a running gasoline engine, where an open EGR valve will have an immediate effect on idle quality, won’t work on a diesel. The TDI really doesn’t care where it gets air; it just needs all that it can get.
Why does my engine stall when the EGR is open?
This is because the temperature is lower so fuel does not burn at the optimal temperature and as a result is less efficient. Stalling when the engine idles like a rough idle is usually caused when the EGR valve is permanently open and is constantly letting exhaust gases into the EGR system.
Why does the EGR valve open on a Trafic Vivaro?
Under certain circumstances it opens up to feed exhaust gases into the air intake of the engine. There are several reasons for this, the first is that it heats the engine up quicker from a cold start, which leads to improved efficiency on short journeys as diesel engines don’t run efficiently when cold.
