Without an engine model number I am making an educated guess but :
Control valve DZ111135
Relief valve RE516335
Should always replace these as a set, the new control valve is longer and there is a software update that accompanies it, the new part and software are both to help alleviate this valve sticking. You will have to modify the mounting of your primary fuel filter to account for this new control valves length, the filter head as well as the filter bracket can be spaced out and back with washers to make room for the control valve.
That's what I found for the parts and wondered if they had revised the SCV because of that. Would the new valve work without the software update until we had a chance to take it to JD?
Here is the picture of our pressure sensor. I cleaned it with brake cleaner and let it dry before I put it back in the rail. I also pulled out the SCV to see if it had anything on it and it didn't, it was clean. However, the clip for the plug is broken off and it seems like the plug isn't staying on there all the way. I can push it on and it will back out just a little bit. After I put the two back in and re-bled the filters, it started back up and had no codes and ran fine. I took it up a steep hill we have in D4 and it ran with no smoke up it at 2300rpms, then I took it back down and moved some bales for a bit and ran it back up the hill. Hasn't set a code yet.
