Trouble shooting procedure glow plugs '93 VW Golf 1.9 diesel


What you need to do is make sure the key is off, remove glow plugs, hook a set of jumper leads to your battry, put the negative lead around the threaded part of the plug, hold the + jumper lead to the top of the plug where the power rail bolts on. DO NOT TOUCH glow plugs as they will heat up hot & fast. If the light comes on 6 - 8 sec thats how long you need to hold the power on. The tip of the plug should be nice & red hot in this time. Repeat for all plugs & see the diffrence If more than 2 are dead (no red heat) or noticably slower than the others It will be very difficult to start & the plugs should be replaced. AGAIN carefull not to get burned.

How do i replace my VW SHARAN 02 glow plug relay. and what is it. i have been told that the glow plug relay is going. Could you please tell me what a glow plug relay is and what it does??? Also do i need...


the glow plug relay is a little black box normally located in the fues box, the relay regulates power to the glow plugs, if the relay is not functioning correctly the plugs will not heat enough or, you will have to allow a longer time to let them heat up, it acts like a switch as such, when you turn on your ignition it switches over to make a contact inside, which inturn starts the heating prosess of the glow plugs when they are at the correct tempreture or the onbored computer detects they are it then switches back , without it , say just using a fuse instead, your glowplugs will just get hotter and hotter till they melted, and no you dont have to change the glow plugs hope this helps, ime not good at explaining stuff in writing lol

Car wont start diesel engine Could it be the 'glow plug'? what is a glow plug? how can i test?


A glow plug is a small heating element in the cylinder. It heats the diesel so that starting can be made easy. Is your car standing in the open frozen parking If yes, then it would require a lot of battery power to first heat all the cylinders and then turn the engine to start. What we do in such conditions is to light up some fire under the car and heat the fuel system enough for the diesel to warm up a little and thus save the battery for glow plugs. Generally, all vehicles have an indicator light which comes on when the glow plugs are ready for starting. The diesel will ignite on compression, but it has to reach the cylinder and thus has to be flowing. In cold it freezes and hence the need for glow plugs and the heat. If it is parked in heated parking then the need for glow plugs decreases.

2000 peugeot 306 1.9 diesel smokey on startup and misfiring when cold but is ok after heating up no wAater loss any ideas


change the glow plugs i used to have a 306 and a huge cloud of white smoke come out of the exhaust on start up lol, changed the glow plugs and was clear as a whistle, its because the glow plugs dont get as hot as the others and fires up on the hottest cylinders so if you have two glow plugs out the other two are being forced to turn over hope this helps you ;)

Glow plug indicator blinking


Your glow plugs are going bad and need to be replaced. This is a sign to you that they are basically running all the time because they dont know that thye are heated up and the car is running. Common problem with diesels

Sounds like bad advice. If your glow plugs are bad, the last thing you want to do is try to start it. Remember, diesel engines use these glow plugs like coils in a toaster. Since diesel is harder to burn than gasoline, the glow plugs heat up to a combustible temperature, allowing the diesel to ignite and your vehicle to start. I don't know the reprocussions of trying to start it without them working...but it can't be good.
