Hi i have a VW SHARAN 02, it starts fine, the glow plug light goes out as normal when i turn the key initially, after the light goes out i start the car. but sometimes whilst driving, the glow plug light comes on and the screen displays 'ENGINE WORKSHOP'. but if i keep driving the light goes out automatically. Why does this light come on and what is wrong with the car, can i repair this problem myself, if so, how???

Sounds to me like you have a bare wire shorting out somewhere. Be sure all your wires are fully insulated.

i think glow plug replacement needed. ever used starting fluid in cold to start?try this, next time no start, cycle your key and let the light come on, wait till it goes off, turn key again until light goes off, if you have to do this more than 3 times, and it runs fine, replace the glow plugs only then. thank you for choosing fixya.com!

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

02 VW Jetta TDI with ALH engine glow plug


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.

Glow plug light flashes on97 tdi sharan


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.
