i'm new here but not to diesels. I bought a 2006crd about 2months ago. I have yet to see the glowplug light come on. although it starts fine. I've pulled the cover and looked for the glow plugs but haven't seen one. where did they mount them?

They are on the driver's side, not really visible from above. You won't see the glow plug light for more than an instant (if that) until the weather gets colder.

.....and even when it's down in the 20s and 30s, the light only stays on for about 3 seconds.

Thanks. I'm in southeast texas and it got down to 65 this morning. It rarely gets down to freezing so they won't get used much. It's nice to know it's working.

the best advice is to read the manual and look at the location of the light while you are turning the engine over and then on. It will only flash for an instant.

I remember driving a diesel van in the Air Force in the 80s that usually took ten or more seconds for the glow plug light to go out no matter the weather.

I'm in South Florida. I almost never see the CRD's glow plug light. After a really cold night here (in the 40s, sometimes the 30s) the glow plug light may be on for all of a whole second.

Ain't technology wonderful?

Here is a CRD glow plug:

Wow, that looks like trouble TDI's have shorter ones and they some time brake off while removing them

I had one replaced a couple of weeks back under warranty, 3 hours labour. Notes on work order indicated that they had to remove the intake manifold so I guess they're not easily accessible.

As others have noted they are on for a very short period. It gets well below freezing here (-25 to -30 degC). Even on the coldest mornings they're only on for a couple of seconds.

A far cry from the Citroen I was driving 15 years ago which took about 10 seconds regardless. Of course, the up side was that they were trivial to replace.

ok just work with me here...

somewhere, it might have been from the dealer.. or someone that workes on the VM said "yes they have glow plugs, however they set off a "grid" thus no waiting for the plugs to heat up."

I even have a sticker that says "warning! ceramic grid may be hot even if motor is off"

am i crazy?? ok wait dont answer that!

or was it a drealer just blowing smoke...

The front glow plug is accessible by releasing the serpentine belt, removing the alternator and some brackets. The rear glow plug (and the EGR valve) are accessible by removing the fuel filter assembly and getting it out of the way. The middle two glow plugs certainly require removing the EGR flow control valve and the adaptor to the manifold and may require removing the manifold itself. The big problem is that the glow plug harness may or may not be installed correctly and the computer might indicate the wrong GP as being bad. A lot of parts might have to be removed before the bad GP is identified.

I read somewhere that a common cause of premature GP failure is hitting the starter to quickly causing the GPs to overheat since they are being heated electrically and by fuel ignition simultaneously. However, the same article said that modern diesels will not activate the starter until the GP’s are off. I don’t know if the CRD has this protection, or not, or if this is even true – just passing it on.

Yeah, this is correct. The starter will not turn until the glow light is out. This is very noticeable in the winter.

There is a yellow warning label on the front of my cam belt cover that reads:

“Caution
Ceramic Glow Plug
Operating Voltage: 7V
Handel With Care!”

The following warning that comes with a new glow plug reads in 5 languages:

“Due to the special properties of the material used, the ceramic glow plugs (Bosch type GSK 3) are easily damaged and require extra care when handling and installing. Transport and store only in original packaging or packed separately in bubble wrap. Do not remove from packaging until immediately prior to installation.

Ceramic glow plugs are sensitive to knocks and bending. For this reason, glow plugs which have been dropped (even from a height of only about 2 cm) must not be installed, even if no damage is apparent (hair-line cracks may not be visible). Always install new glow plugs if you are not sure the old ones are in perfect condition.

If the glow plug is damaged or if the tip is broken, the fragments must be removed from the engine before starting for the first time, otherwise this will cause mechanical damage (piston seizure). Remove the cylinder head if necessary. The glow plugs must not be removed when checking cylinder compression. After removal, the cylinder head must not be put down on the gasket side with the glow plugs still installed, because the glow plugs project beyond the gasket surface.”

Other than some disassembly required, the glow plug job was uneventful. Well, except for the red velvet pillow in my garage on which the glow plug was placed before insertion.

Can anyone explain why the glow plug I removed from the head was not seized after 50k miles and my oil plug seizes between oil changes? No evidence of anything on the threads of the old GP. It was clean and shinny. What gives?

Just to verify this I hit the starter immediately (cold morning) and the starter went immediately before the GP light went out. My glow plug interlock must not be working.
