EGR Valves were developed as a way of reducing pollution. They reduce nitrogen oxide emissions, into the atmosphere, but it also reduces the performance of your vehicle as it introduces hot gases into the air intake. When the EGR valve goes bad or faulty, it must be replaced. A bad EGR valve can really affect the engine’s performance, or even cause it to stop running altogether. We offer 3 types of EGR services: cleaning, blanking and replacement.
If your EGR valve goes bad you may experience one or more of the following:
the engine may stall or have poor idling
there may be a smell of fuel
you may notice you’re filling up more often
there may be sounds that you’re not used to, such as tapping sounds
the engine light may come on
Testing the EGR Valve
An EGR valve can be quickly tested and diagnosed as faulty by connecting to cars diagnostic system, if it has one. This will diagnose any problem and explain why an engine light has come on. Alternatively an EGR valve can be tested using a multimeter to see what voltage is passing through.
