A few weeks ago my 05 tdi jetta's check engine light came on. I scanned my car and it says glow plug cylinder 1 and 3 circuit/open. It was pretty cold here. Then it warmed up last week and the check engine went out. Last night it was freezing again and it came on again. I'm thinking of changing the glow plugs. My question is does this sound like a glow plug fault or something else.
