Plus I dont think any modern diesel engine even have glowplugs anymore. They all have an intake grid heater, which works by cranking the motor and drawing hot air into the cylinders, kind of like the way a hair dryer works.
the new 2.0L VW TDI engine still uses them (my '10 Jetta has them) but they're strong, ran for less than two seconds today in -20C weather (no other heating used, car was on the street overnight)
You think, or you know? Cause it makes a difference. :) Btw. what happens, when the "hot" air pumped into the cyliders is pumped out as the starter begins to work? I am sure, that the engine would suck really cold air then. That wouldn't really work.
@kacprokkk7 you would think that it doesnt work very good, but those grid heaters work great. see, it doesnt have to get the air hot, just warm. like...compare a bic lighter flame to a little portable spaceheater. which one would heat more air to about room temp faster? thats the diference between a glowplug and a grid heater. getting the same end result, room temperature air, but one through a lot of warm grid fins, and the other through one chapstick size super hot piece of metal.
Thats a good trick...for a 80's ford truck. But modern coldstart systems do all that automatically. There is no need to turn the system on & off, as the computer will light the glowplugs to a certain temp, then cycles them. Then when they sense the temp drop they will relight. you would think that they fire each time you turn the ignition on, but in reality they only come on when the computer says to. you can verify this by watching your dash lights dim slightly every few seconds as it cycles.
You said that there's no point in turning the ignition on & off. If so - do tell me why my car wouldn't start after turning the glow plugs on once, but did, without any problem, after turning them on three times? What's more what would be the point of the glow plug indicator staying on if the computer "thinks" the engine doesn't need to be heated any more? If the computer judges, taht it is so, the glow plug (and the indicator) will be turned off quicker. That's it, nothing complicated.
Well, First off we gotta understand that auto manufatureers dont always do what is the best for the car, engine, and owner, and jsut does whats best for their budget, and esiest to fix for the dealers. A grid heater is about the size and shape of a MAF sensor on a gas car, and takes only a few min to replace, instead of a couple hours like a set of glow plugs. Thats why I say most moderd diesels have grid heaters. The reason the light stays on for a few seconds is the same as if there were glow
plugs. Simply because the grid is heating up and getting hot enough to heat cold air that all the cyl are sucking in, instead of heating the combustion chamber. See, a glowplugs work is pushed out of the cyl each stroke, and think of a littel 2 inch 1/4 inch rod's eficiancy compared to a tiny littel high amperage DC space heater with a whole grid red hot heating all the air thats being drawn into the motor. A glow plug cant heat the air in the cyl as fast as a grid can.
Id say that if you have to turnon three times to get it hot enough to start, you need to have it serviced. The cold start system in a diesel engine is the most overlooked of all. The parts are a high performance object, and wear rather quickly. But the good thing about a grid heater is its a lot cheaper to service then glow plugs.
But... after doing a little research the TDI Volkswagen's are still equipped with glow plugs, therefore when they are worn out, will require tuning the key 3 times.
I'm with kacprokkk7 on this one, I have an 03 tdi jetta and this last winter when it was -40 for a week if I didn't "cycle" the ignition it wouldn't even think of starting. I know that the times have changed regarding glow plugs and cold starts but this really does work. I have a friend with the same car and he does the same thing
After researching the TDI a little bit, they indeed DO have glowplugs, instead of a grid heater. The nature of a glow plug, leads them to wear out. high heat in a diesel engine's combustion chamber eats them away slowly. After many miles, they are now shorter then they used to be, therefore do not have the same heating capability they once had. They should be super easy to replace. About like spark plugs on a gas car, and I would bet that the 3x thing will cease.
What brand of oil pan heater do you have? Did it actually raise the temperature of the engine? I have a normal block heater which seems to work quite well.
be careful cycling your glow plugs like that much... you need to wait 1-2 seconds before turning your ignition back on or you can damage the glow plug harness... I did. :(
Can I give you an advice...because the last time I tried to explain to someone from USA, he didnt wanted to listen. If you put on the igniton once.... an then you put it again just wait for the glowplug light to go out and wait about 30-40 sec........ because the glowplugs still work. The indicator on the dashoboard shows only the minimum amount of time that you have to keep the ignition on depending on the temperature. !
Great! I live in a place where the temperature goes to about -35 for a couple days a year. I was hoping the Golf TDI I'm buying would be able to start. Do you think you would be able to start that thing around -35 to -40?
I thought glowing that many times would empty your battery so much it wouldn't be enough juice left to crank it. VAGs deliver with very large batteries though. Do you know how many Ah yours is?
@brenTDI204 you know it keep glowing although the light gets off? you dont need to do that power off, on, off, on think, just let it glow a little bit longer
@AboyfromItaly Yes, I live in the northern most part of Alaska and it gets quite cold. Glow plugs are for pussies!

Why didn't you just start it right away when the glowplug light went out? No need to the the same procedure over and over for like 10 times.

I started up my VW TDI in -55c with no glow plugs!
