I have a 1999 NB. Would having cracks or breaks in the glow plug harness cause a CEL with a P0380 code? I got the CEL over a month ago and without a vag-com have tried to diagnosis the problem the best I can. I found cracks and breaks on the glow plug harness where it attaches to the glow plugs in two different spots. One is so bad you can almost see the glow plug through the crack, the other is just a split. Should I dig deeper or just replace? I have found the harness online and most places sell it for $65. Does that sound about right? Also, what is involved in replacing it? Is it a cut and splice deal? Thanks
