It's been getting a bit chilly here in So Cal lately (50's) and I've noticed that when I go out to start the truck, it lets out a cloud of white smoke and it surges for a few seconds. Seen the heater cycling, but the wait light only comes on when it gets real cold (40's) I've noticed. Anyone have any idears? Once it warms up, all is well, it's just starting up when like sitting overnight. I already had TSB 18-003 whatever that pertains to charging the battery, overhead mpg and whatever it was (I forgot). First diesel, and loving it.
