"Yes Kennedy, you hit the nail on the head (I figured you would), I was told the glow plugs are sticking on from the factory, melting, and then dropping onto the piston causing major engine damage, I still haven't confirmed it myself, but supposedly there are 3 duramax's with less than 60 miles on them and in need of motors sitting at Southfort chev in Fort Saskatchewan Alberta.

Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using the system below. Not all vehicles within the above breakpoints may be involved.



-- GM dealers should use GMVIS.





For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided through the applicable system listed below. Dealers will not have a report available if they have no involved vehicles currently assigned.



-- US GM - GM DealerWorld Recall Information



-- Canadian GM - GMinfoNet Recall Reports



-- Export dealers - sent directly to dealers



The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall.



Parts Information

Do not attempt to order the calibration number from GMSPO. The calibration numbers are programmed into Control Modules via a Techline Tech 2 scan tool and the Techline Information System (TIS) 2000 terminal with the calibration update. Use data version 3. 5 for 2006 or later, broadcast to dealers, and available on TIS2WEB, March 19, 2006 (US), March 22, 2006 (Canada); and on TIS CD-ROM version 4. 0 / 2006, which will be mailed to dealers by April 18, 2006. To complete this service procedure, the Tech 2® must also be updated to release 26. 002 or greater. If you cannot access the calibration, call the Techline Customer Support Center at 1-800-828-6860 (English) or 1-800-503-3222 (French) and it will be provided.



Service Procedure

Glow Plug Control Module Reprogramming





Notice: Before reprogramming, please check the battery condition to prevent a reprogram error of the Glow Plug Control Module due to battery discharge. If the vehicle battery is not fully charged, ensure that it is fully charged prior to performing the reprogramming procedure.



The ignition switch must be in the proper position. The Tech 2 prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so.



Make certain all tool connections are secure, including the following components and circuits:



• The RS-232 communication cable port



• The connection at the data link connector (DLC)



• The voltage supply circuits



DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur.



DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date. Attempt to reprogram the control module. If the control module cannot be programmed, replace the control module.



Tech 2 Remote Programming

Use the normal "request method" through "Service Programming System" to request information from the vehicle.

At the Techline Terminal enter TIS SPS programming system.

Select Tech 2 from the "Select Diagnostic Tool" window.

Select Reprogram ECU from the "Select Programming Process" window.

Select Vehicle from the "Select ECU Location" window.

Select Next to go to the "Preparing for Communication" instruction Screen.

Select Next to view the "Validate Vehicle ID Number" screen. If the Vehicle ID Number does not appear on the screen, manually insert the VIN into the VIN window of the "Validate Vehicle ID Number" screen.

Select Next to view the "Supported Controllers" screen.

Select Glow Plug Control Module from "Supported Controllers" window.

Select Next to view the "Select Programming Type" window.

Select Normal from the "Select Programming Type" window.

Select Next to view the "Service Programming System Calibration Selection" screen.

Select Next to view "Summary" screen.

Verify that current and selected calibration information is displayed on the "Summary" screen.

Select Next to download the calibration to the Tech 2.

Back at the vehicle enter "Service Programming Systems".

Select "Program ECU" and follow on screen instructions.

Make sure to turn OFF the ignition for 30 seconds after the "Programming is Complete". Clear diagnostic trouble codes (DTCs), if required.

What's a glow plug?

 

[Alan Reagan]

What's a glow plug?

It's one of them things that falls off into the cylinder after it becomes electronically challenged.

 

[DWitcher]

Jump starting with the battery still conected is causing electrical power spikes which causes the glow plug tip burst and fall into the piston.

 

[LOtero]

weve had 4 in need of new motors because of the glow plugs. gm is now starting to push on checking the cylinder and head for damage and replace necessary parts. if piston in only slightly pitted or dented its ok by gm. they really want to see if the compression is good then figure what is causing compression leaks if any.

 

[Signal73]

Whooooeeeeee! Thats going to cost the general some serious $$$$ to fix :--)

 

[rbattelle]

My goodness that's a real mess. I just don't get the glow plug thing. Why not switch to grid heaters like we have? Certainly seems simpler.

[Joe G.]

It's not like grid heaters are new technology. I had a '42 Buda marine diesel that had them. Glow plugs seem like dumb engineering to me.

 

[WDixon27]

yea glow plugs are a pain, moms old turbo diesel volvo would want a new set every couple years, but they didn't destroy the motor they would just die gm must be sorcing some real crap for plugs

 

[Rotty]

it could be these new ceramic glow plugs. ???

They heat up real fast for the impatient croud. They are also real sensitive to shock and vibration. It is a serious problem in TDIs.
