On the glow plug issue - I was coming back from a fairly long (500 mi each way) and after filling up jumped in the CRD and brain faded and started it without waiting for the glow plug light to go out. It flashed the GP light for about 3 seconds and then went out but it tripped the CEL about 10 seconds later and has been on since.

Not starting harder, not running odd in any way. 2007 with 66k miles on it. Having normal maintenance done at dealership tomorrow because we're headed on vacation (driving 1000 each way) next weekend so to prepare I plugged in the OBD reader and had 1 code P0671 - glow plug heater cyl 1. I cleared the code and drove it about 10 miles - no CEL, re-checked and still no codes after restarting a couple more times just in the driveway.

I am thinking the my dumb### move with starting before GP light went out tripped it but I have also seen others with real issue with GP's so I am just going to wait but I am having the dealership actually test them to be sure it's not something that just needs the right condition to trip it (hot/cold) and I just hide the issue. Is it just a simple resistance test (infinite resistance is toast?) across each of the 6 plugs to determine if good? If that is the case then it wouldn't make sense that after I cleared the code it wouldn't come back immediately????? Any thoughts on what I am thinking are appreciated.

I've not seen a post about a do it yourself glow plug test. Hopefully someone else can advise.

Glow plugs can be tested with a volt meter on resistance. A good one will be about zero ohms. A defective one will be very high. Mine was 3 thousand something ohms.

Just finished replacing the plug on cylinder number two. Here are my observations. Some paraphrasing and corrections made to info I gleaned from this post and others.




==(PASS)===FIREWALL===(DRIVER)==

5---------------------------- 6

3---------------------------- 4

1---------------------------- 2

=======GRILL=========

(North American Drivers Position)


Glow plug Replacement procedure:

Remove Engine Shroud
Remove foamy thing on top of cylinder
Remove wire from Glow Plug (pull straight up with either needle nose pliers or a pair of dental picks)
Use either 8mm or 5/16 deep well socket to remove glow plug. Do not exceed 20 Nm or 14.75 ft/lb. or 177 in/lb. of torque.
Put new glow plug in hole, using fingers to tighten (this way you know you are not cross threading). Once it is snug use the socket to tighten. Do not exceed 10 Nm or 7.38 ft/lb. or 88.5 in/lb.
Put wire back on
Replace foamy thing
Replace Engine Shroud
Clear engine code
Start Engine and revel in your success

I was unable to locate the plug anywhere except the dealer. I went to my Jeep dealer but will try a MB dealer next time as I have heard they are cheaper there as you avoid one middle man.

Good luck!
Chad

Chad,
I'm not sure where you got your diagram, but here's the numbering that I've seen for the CRD:

==(PASS)===FIREWALL===(DRIVER)==

3---------------------------- 6

2---------------------------- 5

1---------------------------- 4

=======GRILL=========

(North American Drivers Position)

I successfully replaced a faulty #4 two months ago. Yesterday I replaced #2 and reset the CEL. Came back on today with the same code for a faulty #2. Not sure what's wrong, but I may take it back out and reinstall.

I agree with cougar93k, that diagram is what I understand to be correct.

Diagram makes sense to me too, except I would rather sit in the driver's seat instead of up in front of the grill. Seems dangerous.

Well... I sure can't say that.

My glow plug adventure started off by not being one... I took my truck to the dealer for a simple 60K trans service and had them change the fuel filter while it was there. They then gave me the truck back with the CEL illuminated


I happened to wander outback and chat with the mechanics when I complained about the CEL before I even left the delaership and I found out a couple of things. First, they did not have the fuel filter ground wired hooked up and they also did not think to wait for the glow plug light to go out before cranking the motor.

Turns out my truck lost 2 glow plugs and the glow plug control module. They first tried to tell me it was coincidence but my truck ran fine and did not present any codes or the CEL when I dropped it off for service so they backed off that and repaired it under warranty.

I don't know if their crappy workmanship on the fuel filter ground or the cold start on the glow plugs caused the problem or not but it sure was weird.

One thing I do know is that I am damn well sure to use a different dealer next time I need actual shop service.

hmmm, very interesting. I was also not experiencing any glow plug issues when I dropped my low mileage and babied CRD off for service. Later that day I get a call that the jeep won't start and it needs new glow plugs and module. I suspect they broke it while doing the fuel filter and forgot to hook up the ground. Mine was under warranty, so I only had the inconvenience of being without my vehicle while they waited for parts.

Yes you have the correct glow plug diagram lol. There a few different ones out there. I just had the same problem you are having. At 70,000kms a couple glow plug codes came on. I got quoted $750 to fix 3 and they didnt even know if that would solve the issue. My friends dad works at Lordco so I got staff discount. All 6 glow plugs for $126. 15,000kms later #2 code came up again. Brought it back to the dealer and they said they were certain the glow plug is faulty. I switched #2 with #4 and it still said #2 code. Brought it to a different dealer and after my diagnostic they said it is the glow plug control module. Everything is fine after getting that replaced. Hopefully you still have warranty. I think the module is around $400....

For those of you getting a glow plug code its really easy to change them yourself. Change them as soon as you can after driving the jeep so the engine is warm. Be gentle with them when loosening. I just choked up on the ratchet so I didnt have any extra leverage. They all came out fine. When I put them back in I just snugged them up and then a bit. I tend to over tighten things so choking up on the ratchet made sure i didnt.

No warranty. It expired 6 months ago. Just picked up the control module for $182 (girlfriend's father owns an engine shop and gets dealer discounts). Now, if I could only find where the old one is located...

so the lesson is when a glow plug fails, replace it immediately or risk the consequences of a failed glow plug burning out other ones.
if the same glow plug fails more than once, then its the module that is causing the failure, again replace it ASAP because it will only keep damaging other glow plugs.
