car is an '05 e320 cdi with 41k miles.
the car is at the shop for 2 days, they don't have the part, or so they say.
I hope it isn't that they don't know how to replace them.

 

hmmm, hope this isn't going ot be problematic for us CDI'rs as the miles get up there. Let us know what happens and good luck.

 

did all of the glow plugs fail? or just one?

OR

did the coil/component that sends power to the glowplugs fail?

more details when you can pls.

BTW... we have a diesel forum now for diesel specific issues, so our Gas powered W211 friends don't have to be bothered with our oilburner specific issues.. You may also find more "knowledgeable" diesel types hanging out there to add to your discussion.

 

I don't know, I'll find out if and when they finally get it working

 

The car should start without glow except on really cold mornings.

Without glow it will start but run really rough until warmup on the cold days.

If its completely no-start then its the relay/etc. But again, it would have to be really cold, like below 35 degrees F.

If it just runs rough until warm, then its 1 or 2 plugs.

BTW they probably don't have the part, Even a fuel filter was an order item at my dealer. Glow plug replacement is not a big deal, unlikely they don't know how to replace the plugs.

 

OK, got the car back today and the plug in cylinder 4 was replaced all seems well again. I just think that it is strange that they wouldn't have this part lying around the shop and had to get it shipped in from who knows where

 

Well this morning my glow plug light stayed on longer than usual (1 minute in 45 degree weather, not too cold) but also had a check engine light come on as well. Kort, did this also happen to you?
When checking the owners manual, it states it could indictae exhaust issue or diesel electronic issues. I guess i'll take it in to my SA and see what he has to say. I'll keep all posted.

 

yes the check engine light came on, on my car it was 1 plug that was replaced

 

Update:
Just spoke w/ my SA. It was a glow plug that went bad. I should get the car back on Monday. Thanks Kort.

What indicator is that? The coil looking light? Sorry I probably never experience this since I live in FL.

 

Ok, here we go again... another glow plug and CEL today. How many are there? Frustrated as I know it's an easy issue to resolve but time is one thing that is very precious for me. Off to see my SA. I'll keep you posted.

There are six

You have a six cylinder engine.

 

They take about 2 seconds to change. If you remove the two engine covers, they can be accessed with a deep 10mm socket. No other disassembly is required, unlike the previous diesels.

 

Plan for replacement somewhere between 70-90K miles. Varies with you driving -- highway miles = longer interval.

 

How much did it cost to get the glow plug replaced?
