Glow plug diagnositc code/light come on
Hello, this question is for my 92 300D 2.5 turbo with 320,000 miles.

Right now when i go to start the car, the glow plug light does NOT come on. AFTER i just start the car, the light will come on for 1 minute, then go off.

If i remember correctly, isnt there a fault code with this? for example, if the glow plug light "blinks" that means you have a glow plug out but if it doesnt come on its a relay?

BTW, all 5 glowplugs were replaced about 2 years ago. I cant remember when the relay was last replaced.

Thanks in advance...

Yes, you most likely have a bad glow plug. The light comes on after starting when at least one plug is bad.
