Get a chilton's repair manual for your specific car and it should tell you how to and what else you have to do to get fuel back into everything if you lose it. May I ask why you are needing to change your glow plugs on such a newer vehicle? what's going on?

2000 Jetta TDI: How do I change spark plugs on 2000 VW jetta 2.0...

You're in the TDI (diesel) solutions section so it uses glow plugs.
If it's a petrol engine 2.0L then it would be accessible above and below intake manifold using a swivel spark plug deep socket.

How do I gt to the 3 glow plugs in my cooling/heating unit??? (2001 Jetta TDi)

They are absolutely pulling your leg if they're telling you that you have 7 glow plugs. It sounds like they don't have a clue about TDI's.
Everything you ever wanted or needed to know about TDI's can be found at You should even be able to find a knowledgeable guy in your area that would be willing to take a look at your car. These guys know their stuff. Better than any VW dealer on the planet.
Read this thread - you might be able to figure something out on your own:

Are you having problems with your heating/cooling? OR did you get a check engine light and found out about P0380 when you brought it to the shop?
You more than likely have an issue with your glow plug harness. The connectors on the glow plug harness (where they plug into your glow plugs) prob need to be cleaned. Read this thread too:

Sounds like it is telling you that you need to get a glow plug replaced that is not functioning properly. Have a reputable shop let you know which one it is.

Glow plugs are a lot like spark plugs and change much the same way.There not cheap so just make sure that is your problems as the controller can also fail. especially if the all went down at once.
