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.
Hi Drudgery1971, my Jeep is doing exactly the same, code P0671, CEL, I deleted the code and it run ok for 3-4 start-ups and the code reappeared; Is it the gp or the module?
Our 2008 WK CRD 3.0 3500K went to the dealer with the check engine light on and a short glow plug light after startup, just as the comments have stated above. When the service writer called with the report that the replacement of two glow plugs # 1 and # 3 as well as the glow plug module was needed and the car would be read, Parts & Labor coming to $ 736.02. a fuel-flush for $ 158.00 and a new fuel filter in stalled for $ 228.41 plus the Electronic Engine Control Diagnosis II All another $ 112.00 coming to a grand total of $ 1211.38 DOLLARS! Now hearing this from the enthusiastic service writer at the crack of dawn, after dropping the vehicle off the afternoon before and having extended GOLD Plus Plus Jeep Chrysler warranty, was a bit of a shock to say the least!
At this point I requested that the truck be pulled out of the service bay and parked for me to retrieve costing us $110.00 for the diagnosis. Next stop was JeepForum.com and this thread to get to the bottom of this. Armed with the information from this thread, I set out to find the parts and tackle the job myself. Checking online I came up with the parts needed and was ready to hit the check-out button, when my better half asked if i would check locally for the parts that were needed were available at a comparable price. Again thanks to posted information I went to the brand new Mercedes-Benz dealer just down the street from our home and placed a order for 6 glow plugs and a module grand total of $ 330.00 the cost of the module being $ 180.00 and $ 150.00 for the six glow plugs witch retailed for $ 32.00 discounting the price $ 7.00 dollars each as to me more competitive with the internet pricing.
Next we receive the email from the dealer asking if we were pleased with the service performed, or should i say my wife received. Having excellent customer service skills she sends a reply to the Service Manager listing our concerns, to her surprise the reply to her message was return quickly. The tone of this email was we want to make this right.
Bottom line is that Northwest Jeep Inc. Portland, Oregon installed all six glow plugs and the module and replaced the broken key with programing for what we had paid for the diagnosis $ 110.00 dollars. The service manger and general manger met my wife and delivered the car personally.

Hey PDX.... nice to hear a dealer story that turned out good. It does happen at times.
Also nice to know there is another CRD person not too far away.... I see so few of them in these parts.
I am a little confused about your mileage.
3500K could be 3,500 Kilometers.... so its brand new.... doesn't sound right.
maybe you meant 350,000 miles (350K) , or 35,000 miles (35K)
maybe you have 3,500,000 miles (3500K) which seems high for an 08.
maybe I just don't get it. I though 1K was 1,000.
