The EGR is an exhaust gas recirculator. It is an emissions component that takes unburned gases and reburns them in the engine. The light is reset when you disconnect the battery, but comes back on when the computer cycles to the EGR mode and identifies a problem. Check the EGR valve to see if there is a vacuum leak, or if the valve is sticking open or closed. Eventually, this will cause a driveability issue.
