Glow Plugs?
So on my new diesel I am sorry to say the dealer never educated me on what exactly glow plugs were. Yesterday I had my remote start installed and I wondered why the delay was so long (5-7 sec). I called the shop and they said it's because they timed the remote start with my glow plugs. Long story short they told me about them and how exactly they work. My question to you is, how long does it take for that glow plug icon to go off on your diesel? Now knowin what I am lookin for I had a cold start this morning and with the key forward and the glow plug icon came on and left within less that 3 sec? Is this short of time normal? If so I want to reduce the time delay on my remote start, thanks.

Glow time is poroportional to how cold the engine is. If you shut a hot engine off and restart it 1 min later, the wait to start light will be just a flash. If it is December in a cold part of the world, you might wait 20 seconds. 3 Seconds sounds about right given the time of the year.

So your 5-7 seconds might not be long enough when the winter cold hits. I would check to see if this is a variable time or a fixed time. If fixed you might have to go out and do it the old fashon way. Go out into the very cold weather and freeze with the rest of us.

The remote start will go all the way up to a 10 sec delay, and I know no matter what time of year it is here in So Cal. the beach will never be colder than 45 where I live, atleast in the last 15 years I have lived here it hasnt.

Starting a diesel which has glow plugs that are not heated is like not having the spark plug wire on the spark plug on a gas engine. It won't start if they are cold.
Yes it will turn over until the battery goes dead.
You can only break a glow plug during removal or if the GP fails to keep together for some reason.

I have a manual pushbutton for my glow plugs. I don't even bother with them if the temperature is above 60 degrees. Below that give it about 5 seconds, then start.
Below 40 a ten count, start and release the button.
Below freezing, a ten count and hold the button for 10 seconds more, or until the smoke thins out, whichever comes first.
No need to let the computer run the glow plugs just to keep the tailpipe from smoking a little.
All the smoke clears up within one city block after driving away.

I'm not trying to highjack the thread, I'm trying to explain about how much time is needed for the remote start. Not much really.
If you live above 5000 feet, you may have to heat the glow plugs longer.

I don't think you are highjacking just adding valuable info. Keep up the good work.
