You will need a deep well 10 mm socket, a 6 inch extention and a rachet. The glow plugs are located beside the 4 injectors. To get to the glow plugs grasp fimly and pop off like a spark plug wire the bustbar connector from the end of the glow plugs. Then with the 10 mm deepwell socket with a 6 inch extention turn to the left to remove the glow plugs.

You'll find the glow plugs where spark plugs would be in a gasoline engine (in the cylinder heads).
The glow plugs will be smaller than spark plugs and, like a light bulb, will burn out and loose electrical continuity. You can check them in place with an ohm meter:
Remove the wire attached to the positive end and mesaure resistance to gound (engine block) through the plug. Unscrew failed glow plugs and install replacements. Carefully clean around the plugs prior to removal (to prevent dirt entering the engine) and apply the correct anti-seize compound to the threads of the new plugs where they screw into the heads. Be sure the wires are well connected without any corrosion or oxidation (no resistance).
Take your time and work carefully so as to avoid breaking or cross threading plugs. Do not wash the engine with water or detergent as the injector pump is delicate.

SOURCE: 1997 Jetta: glow plugs not working. Glow plugs tested good, ne...

Before you invest in a long drawn out Glow Plug replacement etc. A little known issue occurs on the ALH TDI engines. The temperature sensor sending unit. A small blue module that plugs into the coolant hose assembly will cause a P error on the glow plugs that is nothing to do with the glow plugs at all. The part fails and sends a temp error to the engine computer. I tested all the coolant glow plugs, engine glow plugs and glow plug harness and all worked fine. One of the test procedures for the glow plugs is to undo this sensor that will force the glow plugs to come on no matter what temperature. This confirmed my GP system was functional and the sensor was bad. I purchased the part from local VW dealer for $33 US and installed and it is fine. Dependent on your model it can be square or round. The link to this part for your car is http://www.partsgeek.com/catalog/1997/volkswagen/jetta/body_electrical/water_temperature_sender.html

Be sure to have VW Pentosin coolant on hand to refill coolant system as you will lose quite a bit when removing this part. It is located slightly behind the coolant glow plug assembly.. This is the round ones not the ones on the engine block at top.

Be sure that when you replace it you put in a new rubber gasket seal.. its a round rubber seal that should come with your new part. Dont reuse the old one or you will have a leak.

There is a c-clip that holds this in the hole you slide that clip off and wiggle the sensor out. Coolant will run out of the hole, so do this outside. The sensor is easily pulled out. You will need to insert the new part in teh same hole with new rubber gasket and replace c clip. Then plug in wiring harness and you should be good to go.

You're in the TDI (diesel) solutions section so it uses glow plugs.

Glow plugs stay and wont shut off


Your problem sounds like the glow plug relay is faulty. It sees to be stuck in the closed position. It is mounted on the fuse board.
