Thanks for the correction Travis... clearly my TDI knowledge base is
getting dated. :)

This will have the BEW engine in it so it will likely be the 7 volts and it will burn them up if you put 12 on them. The ALH had the 12 volt and some tuners can make 12 go to the plugs if you want/need to switch from what I have heard.

But the glow plugs are listed in oposite order of the cylinders so #1 cylinder has #4 glow plug. Please correct me if I am wrong but I remember something like that. It is also VERY common to have the harness go bad overtime. Both brother and I needed to replace our harnesses. If the plugs check out then that is your problem as it doesn't take much difference in resistance for the computer to sense something is wrong and through a code up.
