Fernando is correct. But I bet you have a check light on because of a trouble code for insufficient EGR. flow. Good guess. Contact me at autoknowhow@gmail.com

I have this CLE on my dashboard. I asked my mechanic to scan the code and it was P0401 EGR. He said it needs cleaning the valve due to accumulated carbon deposit. He erased the light the light for me using his scanner.
