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

this is a common problem for these cars glow plugs go bad like spark plugs however the smoke would lead to bad mass airflow meter. it is not telling ecu corrcet miss. disconnect mass airflow meter. when cold see if this makes it start better. it should would means you need new m.a.f. glow plug issue take a test light place clamp on positive of battery then pull off glow plug connectors place tip of test light on glow plug the bad one will have a dull light unlike the good one which will be brighter. will need new plugs and wire harness four **** connectors and wire striper and crimper will fix concern good luck

Depending where you live if the temp. is over 45 degrees F the glow plugs shouldn't be needed for the engine to start. Have you ever had the check engine light come on? Your problem is probably not in the glow plugs.

on some diesel engines the glow plugs will cycle after the engine is started. it does sound like your glow plugs are not all working that would cause the hard start and excessive smoke when it does start.

02 VW engine light that stays on


You probably need to replace the glow plug harness. The contacts in the boots that connect to the glow plugs get corroded and throw off the resistance of the circuit. The controller in the VW measures whether your glow plugs are good or not by testing the resistance in the circuit. Test all the glow plugs like DickyIV1 stated and if they are all good try cleaning out the crud on the contacts in the glow plug harness. You will then either need to clear the error code or wait several trips for it to clear itself. If it never clears itself or if it comes back on after you clear it then the glow plug harness is too much of a mess. This is really common on the TDIs (mine needs to be changed but i have been putting it off and ignoring the mil light). When I first tried cleaning the harness on my car it didn't give me a problem for another year and a half. But I knew I'd eventually be changing it.
The other thing to keep in mind is that you should change out glow plugs as a set. It causes less problems in the long run since if one failed you will probably find other will soon fail and it keeps all the resistance close to the same value.
