93 300 D 2.5 L

What would cause the glow plug light indicator (on dash) to illuminate well after the engine has started? Thanks and Happy New Year to all!

Typically a problem with the glow plug system, likely a bad glow plug. Test the plugs where the harness connects to the relay box. Good plugs will read about 0.6 ohms.

my 95 e300d did the same thing. Wiring harness was shot. Replacement was expensive, but I paid labor to have it done. I'd do it myself now, and not forget to reconnect the a/c like the high-dollar mechanic did.

I will check both suggestions and as always...thanks very much

I am very appreciative for all the help I get from this forum throughout the year.

I took all the stuff off in order to gain entry to the glowplugs..thanks to the posts of others. I followed all the suggestions and removed the plugs. Took my time, labeled everything, placed all parts in an orderly fashion. All without a hitch.

I must comment on the amount of buildup in the intake manifold or crossover or whatever you folks call it. That stuff was as thick as molasses and was virtually impossible to remove. I cleaned all the parts thoroughly. I am such a novice but I must say that you folks have been exceptional in guiding me through what may seem simple to you but is monumental to me.

Being warned of dropping bolts and looking for them for extended periods of time, I took extra precautions and firmly maintained a death grasp on each of those babies. Knock on Wood! It worked. I feel like Mikey; I cant believe I did it! As an extra bonus, I didnt end up with extra nuts, washers, or bolts--go figure.

Thanks So Much

Mine did the same thing. A new engine wiring harness cured the problem. Castrol super clean removes the manifold goo beautifully.
