Re: WG 2.7crd 2002 gloplug timing,hard start
Don´t know the crd very well, but from my understanding there is only one coolant temp sensor.
Eventhough the temperature indication is ok at operating temperature, you don´t know this for when its cold. The indicator starts with 40 °C when i´m not wrong.
I will see if i can find any resistance values for this sensor, so that you can check that. I doubt if there is any possibility of flashing the ECM with other glow times.
