There are 2 ways to shutdown the EGR.
1. Disconnect the wire to the EGR
2. Disconnect the MAF
Either one will cause a MIL unless you do the mods listed in earlier posts.
 
I have also found a way to get more power and as good if not better mileage.
 
Take a T and put it in the feed from the vacuum reservoir to the first vacuum control on the turbo. Put another T on the turbo vacuum control line. Tie the 2 T's together.
This ups the boost by an amount you can feel-I have not put a ScanGauge on it to document the difference yet.
I have found that off the line response is much better and the engine has more power.

The glow plugs are not hard to change but it takes a little pick and shovel work to get at them. Error code indicated that it was the front plug that was bad on my CRD but it was actually the rear one. If it is the front plug removing the alternator provide access. If it’s the rear plug removing the fuel filter assembly provides access. If it’s one of the other two plugs then probably removing the CAC house and EGR flow control valve will provide access. Not much unused space under the hood of a CRD.
 
The bad plug was not seized in the head and looked like new. I used a 1/4 inch drive ratchet and had to buy a socket that was designed different than what I had to allow the plug to go into the socket. The plug is small and does not need to be very tight – should be able to sense when it is snug enough unless you know what the torque requirement is and you have a suitable wrench.
 
I wasted some time trying to determine how to release the electrical connector from the end of the glow plug without damage. There is no trick. It just pulls off kind of hard.

mdamick, my 2 hoses was replaced at 68000 miles when the pressure side of turbo
blew out. what I did was kept the old ones and built new ones made of aluminium.
Made the connection hook up with clamps and small sections of hose.
I dont think these will ever blow or wear out again. I used .040 thick material

Did you use a standard pipe bender?
If so, did you have any problem with the 90 bend off the turbo?

I didnt use a bender I started with sheet material and ran it through a roller, turned
it into the right diameter. then you take and wrap say craft paper around the 90
deg. bend, now you have a model so to speak, and then use scissors to cut the
paper 90 model. I cut mine into 3 sections then used the paper sections as flat
pattern lay outs. these patterns are to be duplicated onto flat metal sheet.then by hand, hammer, bend, etc to get the radius. Fit all 3 sections together and weld.
I tell its hard trying to explain in writing, but hopefully you can see how the process
went.

John your problem is the fuel filter element is being clogged. you are getting fuel
but not enough of a flow rate to keep up with the pump to rail system.
I bet your not getting any codes either right? sometimes the code I think was 097
will show which indicates excessive fuel leak.
I use 100 % bio fuel in mine 2005 and had this issue over a year ago. it drove me nutts for a week before i figured it out.
you see the fuel system codes will cover and pick up temperature, and pressures
but nothing will detect the flow rate.
your fix will be to lower the viscosity of your fuel, like gasoline-kerosene-diesel.
if you choose gas keep it around 12 or 13 to 1 ratio as too much gas can cause
damage to motor. safest thing is kerosene diesel or biodiesel.
hope this helps

Fust....... the problem is that if the wiring of the plugs were install wrong then is going to be hard to determine which plug is the one that is bad.
The best thing to do is to check the resistance value first before you pull it out.

If you are still interested to use the SEGR I found the man that sells them. You can get in touch with him at the Jeepforum.com site and his name (blog name) LocoCRD. If you go in go to the second page and his in the middle of the page. PM him and he will tell you what to do. If he does not have any ask him for UFO address, I think that UFO have some already assemble.
