We also have a team of highly trained technicians, making us well-placed to diagnose and treat any EGR valve problems. Make sure to give our team a call on 02 9525 3433.

The EGR is operated by an electric motor controlled by the ECU. The EGR also has a sensor which reports the amount of opening of the valve, back to the
