Hey all. I'm having cold start issues but this is just something I noticed since I'm having the issue. Has anyone noticed that the diesel preheat light is gone after deleting?

I'm currently having bad smoke at cold start up but it still starts. Misses and smokes like a ******* but keeps going and drives perfectly. As soon as it warms up after driving a bit the smoke is gone. I'm pretty sure it's the grid heater because it's not drawing enough juice. But I also noticed I haven't seen that light in a long time.

Anyway thought someone might know if this is something the tuner should have programmed to work.
