How does faulty EGR valve cause turbo failure?
The valve ensures the EGR system is disabled at idle, when it would otherwise lead to erratic idling, and at peak power, when adding exhaust gases would reduce power output. The EGR valve is likely to stick and become coked up on some applications. BTN Turbo warns that this can have a significant effect on turbocharger performance.
What to do when your EGR goes down?
Power goes down and fuel consumption drastically increases. This is because a lot of exhaust get sucked into the intake, diluting the fuel-air mixture. You need to remove the valve, clean the stem, test the vacuum diaphragm with a vacuum pump and go from there. Cleaning the EGR feed pipe will not accomplish anything. 1.
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 are the benefits of bypassing the EGR valve?
The benefits of bypassing an EGR valve are that: More Cold and Clean Air into the engine More Power Less Debris into the engine Better fuel economy Can be done relatively cheap
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?
Why is my EGR valve stuck in the open position?
One of the most common symptoms of a problem with the vehicle’s EGR valve is a rough idle. It is not uncommon for EGR valves to malfunction and become stuck in the open position. This can lead to exhaust gas recirculation, which causes rough idling even when the conditions are not desirable.
What to do if your EGR gets blocked up?
The EGR valve gets blocked up for a number of reasons and when it does, it can effect the performance of the vehicle and become a costly fix. We can completely de-activate the EGR system on most vehicles old & new, our service is a completely bespoke and custom EGR delete service from start to finish.
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.
