Check Engine Dash Light - 2008 GC CRD
 
Hi everyone

This is my first post and I haven't had a chance to scan through everything to see if this has already been addressed.

My mechanic put the OBD 2 and the scan came up with a glow plug issue. He recommended replacing ALL 6 glow plugs and the module at a cost of approx. 850 + taxes - nearly 1000 dollars. I have 92000KM on the truck (approx. 57000 miles). It functions perfectly well, no problem starting, fuel mileage actually may be up a little over last year.

Sounds a little absurd to me to me spend 1000 dollars for a faulty glow plug issue. I would get a second opinion from the dealer, but I have a hate on for their $130 'diagnostic' fee (aka known as 5 minutes to throw the computer on) + $120 to change the glow plug. I have no problem for the $120 parts and labour for the plug...

So the question is: Has anyone experienced this problem and how have you handled it?

I will post this in the diesel section also.

Unfortunately I didn't get it. He is usually pretty trustworthy and when he said it was a glow plug indicator I figured it was an easy fix so i didn't ask for it.

try this..........

Retrieving codes (2005-2010 Grand Cherokee):

Insert and turn the ignition key from "Off" to "On" three times, moderately fast and without pausing ("ON" is when the digital odometer displays):
Tip: use the "count to 5" method, where "1" is the first "On":
Off > On > Off > On > Off > On
0 1 2 3 4 5
0 - Insert key (Off)
1 - On
2 - Off
3 - On
4 - Off
5 - On At the third "On" the odometer display will read "DTC REPORT" and list the codes. If no codes are present the message "Done" will appear.

Glow plug problems are common the the 3.0l along with driver failure, sounds like you have a tech covering his butt... the driver circuits are really quite easy to test with a test light and a witech to actuate the glow plugs. Who knows what the codes were, but I will say glow plug function is going to be quite important in canada coming up to winter ;)

Hey thanks guys. Yes very important by January around here. Will try the key sequence for the codes and report.

after it says dtc report it should give you a P XXXX in that box, if there are no codes I beleive it says done... you want the P XXXX

the code should indicate which glow plug has failed (if it was just 1). often you can replace a single glow plug yourself for $50 part in your driveway, however, it is common for a failure of 1 to indicate they are all about to start going.

Unfortunately it goes from that message back to temperature - no P XXXX. Anyone else had this happen?

if it helps P0671 is plug no1, mine has gone, along with speed sensor, rear discs and pads, and now my sat nav is not working, my car is turning out to be piece of crap!
