It's a relay, not a sensor. It could also be the harness - although I don't believe a harness problem would cause all four plugs to show bad. Here's everything you ever wanted to know about glow plugs: (with photos). Check out the rest of the site too - these guys def know their TDI"s...

My 2006 vw jetta tdi lost power and died wont restart am told need code to restart but dont have right code


You will have to have the fault codes read by a code reading machine . That will tell you why the engine stopped. I am suggesting that you check to see if the cam shaft is turning when you try to start it as the timing belt may be broken. Repair/replace items listed by the codes -reset the CPU with the code reader

Engine light on code is glow plug 2 & 4 but all 4 glow plug are new any idees of other problem it could be


You can get a wiring diagram free at Autozone.com for most cars. You need to register on the site free and then scroll to the bottom of the Web page.

There may be a reference to how the Glowplugs are wired and it is possible that they are wired as pairs from the Timer box. This would mean that 1/2 the Timer box is shorted out or that a Relay that controls just that pair of glowplugs is a bad Relay. If there are 2 Relays for the Glowplugs, just swap them and see if the problem moves to a new pair of cylinders. This would confirm a bad Relay.

You may also have a bad ground. Look to see the wiring for the ground circuit. This would be a good bet if each pair is separately grounded. You could also have a problem with not replacing all 4 as a set. I do not know what VW recommends for this.

Perhaps you should test the Glowplugs. You test them by fixing a battery jumper clamp to the bottom of the casing of the Glowplug avoiding the threads. Then briefly touch the top of the Glowplug with the power cable of the Plus charge. Be careful not to melt the part.

The Glowplug should glow equally between the set. They should not stay dark. And remember, the Timer only has seconds to work. That is all the time the Glowplugs have to vaporize the fuel.

I am curious to know what you find.

These flashes indicate a system error code and will require further diagnosis from a VW diagnostic machine, probably a glow plug has failed.

You may just have a dirty MAF sensor, spray brake clean through the sensor and clear the code, run it a few days to see if the code comes back.
