Refuzn-To-Grow-Up Posted February 1, 2016 Report Share Posted February 1, 2016 I have 2008 Volvo D16 with I-Shift. While driving on the highway, I received a CHECK light with "engine fault." I pulled off of the highway to further investigate and I shut off the engine. When started the engine, the CHECK light was gone. The engine performed well, as it usually does. When I got to my destination, one of the forum members helped me out to diagnose this code as a differential pressure fault for the EGR valve. He said that sometimes a sensor line gets plugged with soot and causes the computer to "complain." The fault code was MID128 PID411 FMI7. The CHECK light came on a second time. And, then it "cleared" itself, as I was driving down the road. This may or may not be related, but, a couple of days before the CHECK light came on, the Diesel Particulate Filter went into it "cleaning" mode. I stopped it because I was in stop/go traffic and the smoke is cause for concern (lots of smoke) for people adjacent to me. Upon further research, I discovered that this is a somewhat common problem with the EGR valve and/or the sensor going bad. Has anyone else "experienced" this problem? If so, how did you fix the problem. For those of you who have a D16 engine, could you post a photo of the EGR valve? This will help me locate it on my engine and check out the possible plugged line. I know! I should probably take it to the dealer, but, they have not always done too well at fixing these types of "gremlins," after I give them a pile of $$$.
