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 the vehicle is relatively new and has low mileage it would be unusual for the EGR Valve to fail so we would check the system for a buildup of soot and if possible clean the intake system.
MFK Auto Care offer an unbeatable solution for your expensive EGR Valve blanking trouble. We can blank your EGR Valve at the manifold and disconnect it so it is no longer required.
Unfortunately on some vehicles, like Toyota or Lexus, we are unable to blank your EGR valve so we can offer you the choice to have an EGR valve replacement service.
Symptoms of a Faulty EGR
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.
