Hi Patrick.

I would check that you are getting a live feed to your glow plugs terminals first, on cold starting, with a 12v test light.

Expensive to renew them, and then find it was the fuse or relay !

Best of luck !

SOURCE: glow plug timer fuse on 1984 Ford F 250

not a fuse ! Its a 60 amp circuit breaker under dash . If your glow plug timer is not working it most likely needs replaced ! it is located on top of the engine behind the air intake . if you don't know where it is , ask for the diagram at your auto parts store . they will also give you the exact location of the breaker and print it out for you .

SOURCE: glow plug timer

I think the timer is under the sloinoid wich is under the airfilter. My timer went out so i just ran some wires from the sloinoid to a toggle switch in my truck and just warm em up like that, i just took the timer out of the equation

You have or more burned out glow plugs and likely will need a new glow plug timer control.

Got a Renault kangoo 1.7dci the glow light does not go off although van starts ok and seems to drive fine

Best to have the ECU and IP scanned. IP could have shorted leaving the light on. If a relay is stuck or ECU keeps the glow plugs hot. This will eventually burn out the glow plugs.

Follow the glow plug wires to a common box where all the glow plug wires congregate. This should be the timer.

2002 mercedez-benz sprinter van schematics glo plugs

Hello try to measure the voltage at the glowplug wire with ignition on.

It must be at between 5 and 12 volts.
They need to be changed at 60000 to 80000 km.
Because at this mileage they are normaly burned out.
Each plug can drag 8 to 10 amps, when on.

If no reading volts, the glow plug relay, and maybe the plugs must be renewed.
There should also be a big fuse at the firewall, check that also.
Follow the glow plug wire, where it goes to.
Does the glow plug lamp light up in the dashboard ??
Are the relay clicking ???

Check also for blown fuses, resistors, or broken wires.

If you change the glowplugs, DO NOT overtighten them, not more than 15 NM !!!

Good luck

Glow plug light dose nt cycle like it should.

This is caused by burnt out glow plugs, when the glow plugs fail it changes the resistance so the glow plug controller/timer doesn't cycle properly, it is the same as when a turn signal bulb burns out.

Glow plug burn

It sounds like the timer is not turning off the glow plugs as is should. At least not consistantly. You may want to cycle them several times and verify they do turn off every time.

2001 Jetta Tdi runs rough

Hi Whitneyford
Your priblem sounds more like the glow plug timer relay than the exhaust. White smoke after start up is a sign of diesel entering the exhaust before it has burned completly. This is as a result of the glow plugs switching off too early, which is usually caused by one or more faulty glow plugs or a faulty timer.With engine COLD, IGNITION ON... Check voltage with all 4 plugs connected. You should have a reading of 10--12 volts
If there is no power, check in-line fuse on loom coming to plugs.
If power is present, check for How Long. If only for a few seconds, the problem is with the timer. This unit (the larger of the relays and usually black in colour) is fitted on the fuse board, and there are a few different types. They come in 7 pin..8 pin..and even 9 pin units.
The glow plug light is often NOT accurate (even with a new timer unit fitted) as to the time of heating, and you will almost certainly find that power will flow to the plugs for quiet some time after the light goes out. This is not unusuall with The Jetta Tdi.
Good luck.
I hope this helps you sort out this problem
