I'm working on my tune trying to find the coolant glow plug map. It gets pretty cold here and since I don't have egr it's hard to get heat out of the car. From what I can tell with the heat on max and defrost on, the coolant glow plugs run til about 130-135 deg F. I'd like to extend that. I don't have an exact damos for this car so I'm kinda wading through some similar ones. Any help is appreciated.
BTW its a 2002 VW Jetta TDI ALH
