What is your question?
I have this light on in my dash, end i do diagnostic test, end the answer was: low flow detected, end 4 probable cause: EGR-passages blocked EGR-pintle stuck closed EGR-volume control valve open or shorted EGR-temperature sensor error. So; my cuestion is, how i know wich is the real cause of my service eng light.
