Had the glow plug light come on for the first time ever, in 14 years, and whilst driving. Stayed on. Toggling the ignition a few times when parked eventually made it disappear after a fuel stop.
My understanding is that the glow screen runs on a timer influenced by the coolant temp, and it should only be on for about 90 seconds at most. Mine was lit on the dash for about an hour. I didn't notice any performance deterioration with the light on or off so put it down to a false fault indication somewhere, due to a very wet and snowy day and / or whilst EGTs were up around 800C most of the day towing throwing off a sensor. It stayed off. However the next day the engine refused to fire on a healthy starter and hence Fuel cut solenoid - [Leaving Land Cruiser Club] After sitting for an hour it fired up without any drama and has been fine since, so I've not been able to determine the cause of either as the condition has gone. But it is unusual that the first ever glow light indication was so close to the first ever no-start that it may not be a coincidence.
What might cause the light to stay on? I've had a look through the EWD, and RM184E, and RM172E but there's no reference to a glow screen but rather glow plugs, or the conditions for the combination lamp to illuminate.
