Can a diesel engine have an EGR problem?
EGR valves are fitted to both petrol and diesel engines. The EGR Valve system effects all vehicles and below you can see we have had experience with all types of vehicles suffering from EGR problems. How much are you expected to pay on average for repairs?
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.
What happens if you ignore the EGR warning light?
Ignoring the warning lights and allowing the EGR valve system to continue getting blocked up will eventually lead to a complete failure of the EGR system in which case it would require a replacement unit instead of cleaning. If you pick up on the problem and get it treated right away, then having the EGR removed and cleaned is not so expensive.
Why is the EGR system in my car so hot?
The EGR system recirculates exhaust gases back into the engine in order to decrease cylinder temperatures and NOx emissions. The gas circulated by the EGR system can be considerably hot however, especially in vehicles equipped with diesel engines.
What happens when you have a bad EGR valve?
The engine will have a rough idle when the EGR valve is faulty because it will remain in an open or closed position. This implies that too few or too many exhaust gases are entering the chamber, and this is why the engine is idling.
How does EGR off in tune work on a diesel?
Hot exhaust gasses are diverted into an egr cooler off the exhaust manifolds, then they are cooled by the egr cooler, and the flow of the cooled exhaust gasses into the intake manifold is controlled by the egr valve. Egr off in a tune, turns off the egr valve.
Why does my EGR make a Claggy mess?
Makes an almighty claggy mess that is hard to clean up! The same goes for your motor when the PCV Valve and EGR System get together and decide to have a party like two naughty kids and cause mischief without you knowing. Valve, causes a claggy, sticky, build-up of Carbon that eventually solidifies over time.
Can a bad EGR cooler cause an engine to overheat?
If the EGR cooler has any issues that restrict the flow of exhaust gases through the cooler it can cause the engine to overheat. Over time, carbon can build up on the inside of the EGR cooler and restrict flow through the cooler.
