Hello, my vehicle is currently at 99k miles and around a week ago I had got the glow light that would come on during starts for about 10 seconds. Currently, when starting the vehicle the glow light remains on for a minute and disappears, however the CEL remains on. I have no issues starting the vehicle. I was able to scan the vehicle and got code P0672 for the 2nd cylinder glow plug. Should I go ahead and replace all? Also could it be an issue with the control module?

There are no "P" codes in any CDI or Blue module.

Oh wow, not sure. This is what I see on my Scan tool.

Had the same issue more than one year ago with one glow plug failing and the light staying on about 10 seconds after cold start. Replaced the only glow plug that was broken and 20'000 km later no issue at all and no other glow plug has failed.

Here are the codes for CDI. You need a scanner instead of a cheap code reader.

Did you DIY for the single glow plug, If so where did you buy it from?

Oh okay, I will try scanning it with a better tool, and let you know
