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.
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.
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?
Is the EGR valve required for the MOT?
No, the EGR valve system is not a requirement for the MOT. Removing the EGR can in fact improve carbon emissions of the vehicle so it could in actual fact help to improve the vehicles emissions providing the EGR Removal (EGR Delete) session has been carried out professionally.
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.
How does the EGR valve position sensor work?
The position sensor of the valve is linear and provides a signal proportional to its supply voltage (usually 5V). The EGR valve position sensor signal is set to increases in the direction of the opening of the valve. The position sensor is used for three main reasons:
Why does the fuel management light stay on when the EGR is open?
This means the amount of hydrocarbon gases emitted from the tailpipe increases significantly producing a fuel smell. Your engine management light may stay on once your car detects an issue with the EGR valve. This could be caused when the EGR is either constantly closed or open.
How is exhaust gas circulated in an EGR system?
Most EGR systems have a by-pass valve integrated with the EGR cooler. When the engine is cold, the exhaust gas is circulated directly into the engine.
