96 E300D Glowplugs
First problem I had was the check engine and check engine electronics came on but no glowplug light lit when key was turned on found one glowplug reading about 700 ohms replaced all glowplugs with bosch duraterm glowplugs. After replacing all glowplugs checked resistance at the relay and they are reading .6 ohms. Disconnected battery neg. to clear check engine light but it did not clear the display or check engine light. Went to autozone and checked the code and it is glowplug heater circuit. Also checked the voltage at the relay and all terminals were about 12.8 volts. Does anybody have any ideas to what the problem might be..

Did they clear the code? If not, just drive normally for a few days and it will go away.
Note that starting the car before the plugs get up to temperature will also throw a glow plug code. |

I think on this year car you can reset the codes by disconnecting the battery

Do you no if the relay has a built in temp sensor or is it on the engine alot of the wiring isolation is coming off on different connectors on the engine. Do you have a wiring diagram for the glowplug circuit?

PO380 occurs when start is attempted on cold GP's. Most commonly is user error, sometimes the relay. Will go out on its own if doesnt reoccur within 3 cold, hot, back to cold run cycles.
The wiring is part of the overall engine harness unfortunately. Is not sold separately.

I checked the voltage with the glowplug connector off and the relay does not shut off the voltage is on all the time the relay does not time out do you have any ideas

Disconnecting the battery doesn't reset anything on my '96.
