Help, glowplugs dead after 4 months!
I replaced all 5 of the glowplugs on my 300D in December and now I have the same no light no start problem. I checked the resistence of each plug (from the 6 slot connector to ground, on the 200 scale) and glowplug 1 and 3 show 1.5-2.4 and 1.3-2.8 . But glowplugs #'s 1,4, and 5 show 0.00 ! They should show either a low number(if good) or infinity (if bad). Glowplugs are really just resisters that produce lots of heat so they should have a high resistence like 1.5 on the 200 scale = 300 ohms. Zero makes no sense at all to me. Is there a short somewhere or inside the glowplugs themselves?

I had three glow plugs go bad after about a year. I tested them from the terminal and then tested them right at the plugs. I got a reading of infinity on 4 and 5 and a reading of something other that 1 on numbe 3. After talking with a trusted MB tech in the area he told me that there was a bad batch of, if I remember correctly, Monark Diesel glow plugs produced last year. This was news to me. Anyway, I bought 5 new Bosch plugs and installed them. No problems after that. I must note too, that I couldn't understand why my car wouldn't start even with the "new" plugs that I installed last year. My tech suggested testing the plugs and thats when I found the bad ones. I've learned now, if there is a no start situation, always check the plugs first. It will save you headachs.

It is possible that the glowplugs were incorrect for your engine and the heat killed them. May even be a power problem, too much power would, in theory, burn 'em up as well. Or could just have been a bad batch of glow plugs. I had dead glow plugs and didn't know it. I didn't ask why they died, I assume they were just old. Starts up beautifully now.

The plugs should have a resistance of .75 - 1.5 Ohms.
