Frequently asked questions

What is an Exhaust Gas Recirculation (EGR) Valve?


An exhaust gas recirculation (EGR) valve reroutes some of the exhaust gases which are emitted by your Mazda's engine into the combustion chambers to reduce the nitrogen oxide emissions in petrol and diesel engines.

What are the common symptoms of an issue with the EGR valve?


An EGR valve can fail by remaining permanently open or permanently closed. If the EGR valve is stuck open, you’ll notice one or more of the following symptoms in your Mazda:

  • The vehicle does not idle smoothly when starting or at low engine speeds
  • The engine stalls when idle
  • There’s an increase in fuel consumption
  • Your Mazda smells of fuel while it’s running
  • Your Mazda fails its emissions test
  • The ‘Check Engine’ light is on
Common symptoms if the valve is stuck open include:
  • A tapping noise coming from the engine at low RPM
  • Loud and potentially harmful ignition detonations
  • Your Mazda fails the emissions test
  • The ‘Check Engine’ light will be on

How to replace the EGR Valve?


If it’s broken, you’ll need to replace your Mazda's EGR valve straightaway to prevent further damage occurring. The process to replace the EGR valve is as follows:

  • Locate the valve
  • Undo the bolts
  • Disconnect the electrical connector
  • Replace the part
The cost of labour when replacing an EGR valve can vary, as locating the valve can take more time on some vehicles than others.

What does it cost to replace the EGR Valve?


EGR valve repair depends on the make and model of car. As a guide, you should expect to pay between £150 and £300.

Average rating for  Mazda EGR Valve  bookings

5.00

EGR stands for exhaust gas recirculation. The EGR valve links the intake manifold and the exhaust manifold. It plays a vital role in helping to reduce the amount of NOx emitted from your Mazda.


Over time, EGR valves can become clogged due to a build-up of soot, and when this happens, an EGR valve clean or replacement is required.


Common symptoms of an EGR fault include rough idling, erratic engine functioning (including stalling), increased fuel consumption and higher emissions.


Many manufacturers recommend using an EGR cleaning service every 50,000 miles; doing so helps prevent performance issues and extends the component's life.


EGR valves typically have a lifespan of around ten years. After this time, it's usually best to book an EGR valve replacement for your Mazda if you experience any of the symptoms listed above. A stuck EGR valve will speed up the process of the diesel particulate filter (DPF) becoming blocked.
