I live in west coast BC. Normally the temp doesnt drop below 0 degrees Celsius but I have to pull my cod start lever all the way out to get 86 Jetta TD started in the mornings. Is this normal?
Cheers,
Etienne

I pull the cold start out even in summer. If the engine isn't at 190° F, its cold. :wink:

Thanks. Just what I needed to know.

never pulled the lever...

in portugal, where i live and work in the winter temp´s go from -1ºc to 10ºc... warm engine is when it reaches 80º.
cold? well, cold is ambient tºc...

you must be having timming probs or injection bad pressures...

even when the temp here reaches -5ºc I just let the resistance light go off... twice before the startup...

cheers

Why double glow? All you have to do is glow it once and use the cold start knob as it was intended?

The cold start knob doesn't cost any thing, and double glowing for a couple degrees below frezing will shorten your glow plug life.

I usually don't have to double glow unless the temp is below -23° C

And I'll gladly use the cold start knob instead of advancing the beejeepers out of my timimg so its starts good cold, but rattles like a beer can full of pebbles when warmed up. Thanks for the tip :roll:

theres actually a technique where you turn the engine over without glowplugs, for about 1-2 revolutions, then let it glow. this is to superheat the diesel that is touching the glow plugs. the motor should fire right up when following this method. if not, your glowplugs are bad.

I find mine starts up "better" with the lever out.

Are there any disadvantages to driving with the lever out?
Does it increase the amount of diesel or just advance timing.

it advances timing at idle, so no real issue driving with it out

I stumbled across this method. Mine starts up much easier if I hit the starter for a sec them off and back on to let the GP's get hot then fire it up.

Its still pretty cold here in Utah and my car had been sitting for 2 weeks not plugged in, I fired it up yesterday after work just because I needed some diesel in my blood :twisted: , fired right up.

No cold start lever.

I can start mine too without the lever. It just runs a little smoother at cold idle with it out. The bearings in the engine and the turbo will be happier if they are allowed to gently warm up rather than getting a quick goose of the go pedal to get them all firing. And unburned or partially burned fuel out the exhaust port or on the cylinder walls and then into the oil pan is not a good thing in either case.

It make sense to me to have a modified advance for the brief period of engine warm up, rather than run more total advance all the time just to avoid the arduous task of pulling the cold start lever.

according to vw you have to pull the advancing knob only after the engine is cranked. :arrow:

You mean like after its already running? doesn't that defeat the purpose?

Its called a cold "START" lever for a reason lol not a cold run lever. but hey, i guess vw knows best

i find with mine set at 1.00 and with the lever out it starts and idles right after starting ALOT smoother then without using it.

So I tried JT's trick to coat the glow plugs with diesel do
ing a couple of pre-cranks and it was a no go. When I have some time I'm going to remove the bus and check each plug individually. Is there some tips to removing the bus and glowplugs behind the IP,if thats what I have to do. It looks like it could be a frustrating job.

Mine cranks faster with the cold start in. With the knob out the earlier injection makes it harder to crank. I pull it out as soon as it fires up.

i think someone on here not to long ago actually figured out that it advances it by like roughly 27 degrees or something. That is a ton! Why would you want to double glow? why not not save your time and just pull a small lever out ?

I would use mine all the time, it just makes it easier on the engine, and its better for the environment. i think?
