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.
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 there a permanent fix for the EGR valve?
Other than cleaning and replacing the EGR valve system, there are two other more permanent solutions. Cleaning / replacing is a temporary fix to the on-going issues that many motorists are experiencing. So, what are your other two options?
What is an exhaust gas recirculation ( EGR ) valve?
What is an Exhaust Gas Recirculation (EGR) Valve? An Exhaust Gas Recirculation Valve, often referred to as an EGR valve is a mechanical flap designed to recirculate exhaust gasses back into the engine before they exit the exhaust into the atmosphere.
Is there a hole in the intake manifold for EGR?
The phenolic spacer for the stock intake manifold (between lower and upper manifold) has no hole for the EGR gases, so no hot exhaust gas can enter the upper IM, lowering intake temps drastically (the combination of the spacer and removing EGR spacer coolant lines.)
What is the purpose of an EGR valve?
The EGR valve or the Exhaust Gas Recirculation valve can be found in most of the modern fuel-powered vehicles (petrol and diesel), and the purpose of these things is to help reduce engine emissions, by sort of “recirculating” some of the exhaust gas back into the engine.
What’s the point of a EGR block off plate?
Burning cooler produces less NOx, which is something that causes acid rain. In a nutshell, engines that are matched to their current use are the most efficient and produce the least nasty byproducts. Your engine can’t shrink at idle, so they effectively shrink it by filling part of it up with inert gas.
What happens if you have a broken EGR valve?
EGR valves are more commonly found in diesel engines these days and when fully functioning, they reduce emissions greatly. If you have a broken EGR Valve, you will want to make sure it is kept closed and not always open. If the valve is always open, too much gas will go to the engine and this can break many other things.
