Seems like I've read somewhere the glow plugs on our Cruzes are supposed to last 100K miles. I'm at 165K and still on the originals. I have noticed the past couple days when remote starting, it sounds a bit different for the first few seconds. I may just be overanalyzing. :)

Either way, Can someone with access to a service manual please post the replacement procedure here?

Not sure the design on the glow plug on the Cruze. Had a 95 Mercedes and broke a plug off in the aluminum head, never got it out, also there was a special tool to ream out the carbon on Mercedes, I know you have a older Mercedes diesel. Just be careful if removing them. Good luck.

I'll get you some info on it. But I'm sure the car would let you know if they were bad or going bad.

After consulting the information on the system, I can conclude that you should not worry about the glow plugs unless you are getting a check engine light, or the wait to start light is behaving abnormally. The glow plugs have their own module, and the system monitors not only voltages, but glow plug temperatures. If something is wrong with the glow plugs, the car will let you know through the wait to start light or the check engine light. As for changing them, you need a special tool, but other than that they come out pretty much like spark plugs, looks very easy on ours.

where did you get your documents? They look professional and I’d like access to a source such as yours. Thanks

Looks like the Factory Service Manual.
