Does a diesel have an EGR valve?
EGR stands for Exhaust Gas Recirculation and virtually all modern cars, petrol or diesel, employ this technique to control pollutants in the exhaust via an EGR valve. Some use what’s called ‘internal EGR’, where there is no EGR valve as such.
Where does the EGR valve in an engine come from?
So NOx in the atmosphere is not good. That’s where the EGR valve comes into play. It is designed to reduce the amount of NOx emissions from automobiles. This is accomplished by recirculating a portion of the exhaust. Engines have a small passage between the intake and exhaust manifold. The EGR regulates this passage.
Where is the EGR valve on a Hyundai Santa Fe?
Answer: You will find the EGR valve for the 2011 Hyundai Santa Fe by facing the engine, on the right side of the engine, look towards the back of the engine, very near the firewall.

Question: Where is EGR valve located on a 2003 GMC Envoy XL? Answer: The purpose of the EGR valve is to recirculating engine exhaust gas to the back to the engine cylinders.
How is the EGR valve controlled in a car?
It is a straightforward system which utilises a vacuum to switch the EGR valve from closed to open. The vacuum is often regulated by a computer-controlled solenoid. Most modern cars utilise an electronically controlled EGR which is controlled by the vehicle’s engine control module (ECM).
What are the symptoms of a failing EGR valve?
What are the symptoms of a failing EGR valve? A faulty EGR valve can cause problems with the flow and operation of the EGR system leading to performance issues including a reduction in power, reduced acceleration and decreased fuel efficiency. It can also cause vehicle emissions to increase.
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.
What can I use to clean an EGR valve?
This is a home experiment and an unbiased use of JLM Diesel Air Intake & EGR Cleaner. Similar products are available. This product is designed to dissolve carbon deposits, gum and varnish build up. It should restore air flow to the engine thus improving power and acceleration while reducing exhaust smoke.
